need help with mitsubishi p u image printer our group recently bought a mitsubishi p u video printer and i could use some help with it we bought this thing because it has a parallel data input in addition to the usual video signal inputs and claimed to print gray level images however the manual that came with it only describes how to format the parallel data to print and bit pixel images after some initial problems with the parallel interface i now have this thing running from a parallel port of an hewlett packard workstation and i can print and bit pixel images just fine i called the mitsubishi people and asked about the level claim and they said that was only available when used with the video signal inputs this was not mentioned in the sales literature however they did say the p u can do bit pixel level images in parallel mode but they didn t have any information about how to program it to do so and they would call japan etc frankly i find it hard to believe that if this thing can do bit pixel images from the video source it can t store bits pixel in the memory it s not like memory is that expensive any more if anybody has any information on getting bit pixel or even bit pixel images out of this thing i would greatly appreciate your sending it to me thanks allan weber signal image processing institute university of southern california weber sipi usc edu

re sgi sales practices was crimson was kubota announcement my comment regarding dec was to indicate that i might be open to other vendors that supported opengl rather than deal further with sgi opengl is a graphics programming library and as such is a great portable interface for the development of interactive d graphics applications it is not however an indicator of performance as that will vary strongly from machine to machine and vendor to vendor sgi is committed to high performance interactive graphics systems and software tools so opengl means that you can port easily from sgi to other platforms there is no guarantee that your performance would be comparable what i am annoyed about is the fact that we were led to believe that we would be able to upgrade to a multiprocessor version of the crimson without the assistance of a fork lift truck if your sales representative truly mislead you then you should have a valid grievance against us which you should carry up to your local sgi sales management team feel free to contact the local branch manager we understand that repeat sales come from satisfied customers so give it a shot i m also annoyed about being sold several personal irises at a previous site on the understanding that architecture would be around for a while rather than being flushed as one of the previous posts stated the personal iris was introduced in and grew to include the d d d and d as clock rates sped up over time as a rule of thumb sgi platforms live for about years this was true of the motorola based series the pi the professional series the early d s the power series parallel systems individual cpu subsystems running at a particular clock rate usually live for about years new graphics architectures at the high end gt vgx realityengine are released every months to years these are the facts of life if we look at these machines they become almost archaic after four years and we have to come out with a new platform like indigo onyx challenge which has higher bus bandwidths faster cpus faster graphics and i o and larger disk capacities if we don t we become uncompetitive from the user perspective you have to buy a machine that meets your current needs and makes economic sense today you can t wait to buy but if you need a guaranteed upgrade path for the machine ask the sales rep for one in writing if it s feasible they should be able to do that some of our upgrade paths have specific programs associated with them such as the performance protection program for older r based power series multiprocessing systems which allowed purchasers of those systems to obtain a guaranteed upgrade price for moving to the new onyx or challenge r based bit multiprocessor systems now i understand that sgi is responsible to its investors and has to keep showing a positive quarterly bottom line odd that i found myself pressured on at least two occasions to get the business on the books just before the end of the quarter but i m just a little tired of getting boned in the process if that s happening it s becausing of misunderstandings or mis communication not because sgi is directly attempting to annoy our customer base maybe it s because my lab buys sgis in onesies and twosies so we aren t entitled to a peek under the covers as the big kids nasa for instance are this lab and i suspect that a lot of other labs and organizations doesn t have a load of money to spend on computers every year so we can t be out buying new systems on a regular basis most sgi customers are onesy twosey types but regardless we rarely give a great deal of notice when we are about to introduce a new system because again like a previous post stated if we pre announced and the schedule slipped we would mess up our potential customers schedules when they were counting on the availability of the new systems on a particular date and would also look awfully bad to both our investors and the financial analysts who watch us most carefully to see if we are meeting our commitments the boxes that we buy now will have to last us pretty much through the entire grant period of five years and in some case beyond that means that i need to buy the best piece of equipment that i can when i have the money not some product that was built to paraphrase one previous poster s words to fill a niche to compete with some other vendor i m going to be looking at this box for the next five years and every time i look at it i m going to think about sgi and how i could have better spent my money actually your money since we re supported almost entirely by federal tax dollars five years is an awfully long time in computer years new processor technologies are arriving every years making a year old computer at least and probably generations behind the times the competitive nature of the market is demanding that rate of development so if your timing is really years between purchases you have to accept the limited viability of whatever architecture you buy into from any vendor there are some realities about the computer biz that we all have to live with but keeping customers happy is the most important so don t give up we

re virtual reality for x on the cheap hi steve as the author of multiverse i feel i had better respond to your mailnote questioning whether anyone had managed to compile this software the quick answer is yes the long answer is yes but a few have had a few problems with their platforms not all unix s are the same you know as far as many bugs go it would probably be more useful to everyone including you if you were a bit more explicit platforms it has succesfully compiled and run on are rs dec ultrix sun solaris so it is possible the main problem is that i don t have access to other platforms than the rs so if there are portability problems then the only way i hear about them is by people letting me know and giving me a clue as to how to fix it as far as the software not doing anything do you really think i would bother releasing it if that was the case perhaps you didn t read the few docs that are supplied the dogfight world is made up of clients only so if you re in there on your own then you re not going to see anything the dactyl world has quite a lot of scenary so if you don t see anything there then this is definitely a problem one final word if you re not interested don t bother with it if you are interested then please remember that i m not asking for any money so why not try a little patience and constructive criticism maybe that will get results robert robert acsc com

cview answers a very kind soul has mailed me this reply for the bugs in cview since he isn t in the position to post this himself he asked me to post it for him but to leave his name out so here it comes cview has quite a number of bugs the one you mention is perhaps the most annoying but not the most dangerous as far as i can determine it has to do with the temp files that cview creates cview gives the user no control over where it places its temp files it just places them in its current directory the problem you mention occurs as far as i can tell when it runs out of disk space for its temp files it seems as if cview doesn t check properly for this situation as cview decodes a jpeg it seems to write out a temp file with all the pixel data with bit colour information then for bit displays it does the dithering again writing another file with the bit colour information while it is writing this second file it also writes the data to your colour card then when it does the last chunk of bit data it recopies all the data from the bit file to your screen again it does this last recopy operation for its fit to screen feature even when this feature is not enabled the result of this process is the following if it runs out of disk space when writing the first bit file all you ever see is as much data as it has room for and the last bit of data is simply repeated over and over again because cview never realizes the disk has filled up and disk writes reads aren t performed if it has enough room for the bit data but runs out of room for the bit data you see almost all of the picture as it does the dithering and writes to the screen card however then when it finishes the dithering and recopies the data from the bit file to screen for whatever reason it does this one again just gets a repetition of the last chunk of data for which there was room on the disk this is just a guess but probably fairly accurate at least the general idea is on track i think although i have probably made errors in details about file i o etc the way around this is of course to clear up sufficient disk space the temp files for large jpeg s x and bigger can be very large meg meg on some of the largest i have needed in excess of meg free disk space cview has a much more serious bug if you are trying to display a file from a floppy and you change floppies while cview has some temp file open on the floppy then cview in certain circumstances will write the directory and fat table i can t remember for the removed floppy onto the newly inserted floppy thus corruptimg the new floppy in a very serious possibly unrevcoverable way so be careful it is incredibly poor programming for a program to do this on the other hand when choosing files in the open files menu cview insists on doing a few disk reads every time one moves the hi lighter square incredibly annoying when it could do them all at once when it gets the directory info and really how much effort does it take to sort a directory listing with much thanks to the originator of this article rene walter renew stack urc tue nl will i drown in tears of sorrow is there hope for tomorrow will this world ever get better can t we all just live together i don t wanna live in strife i just wanna live my life i deserve to have a future the good girls future

questions about plane eqn method of hidden surface removal what are the main advantages of this method i have seen it described and the algiorithm seems a little bit long i developed my own method which requires that the points be in a counter clockwise order and returns whether you are looking at the back or the front similar to the plane eqn method it uses few calculations however basically it is several comparisons the only disadvantage i see is that it must be done after the transformation from view coordinates to coordinates to display on the screen which means that a little more calculation isneeded beforehand my method basically figures out whether the points that will appear on the screen are clockwise or counterclockwise when looking at the back of something the points occur in an opposite direction from the front so merely by figuring out which way the points go you can tell whether you are looking at the back or front of a d polygon has anyone heard of this method before it is so simple i doubt i am the first to think of it libertarian atheist semi anarchal techno rat i define myself tsa cellar org

re need a good concave convex polygon algorithm in article c juyz aly murdoch acc virginia edu rws v uvacs cs virginia edu richard stoakley writes we need a good concave convex polygon conversion routine i ve tried a couple without much luck please e mail responses and i will post a summary of any replies thank you richard stoakley rws v uvacs cs virginia edu the problem is not precisely defined above but if you need to find the smallest convex polygon that encloses a given polygon then you are seeking the convex hull of your original polygon there are two ways to do this use a somewhat tricky but by now well examined linear time algorithm that exploits the polygon boundary or just feed the vertices of the original polygon to a convex hull routine and accept o n log n both methods are discussed in preparata and shamos for example

re please recommend d graphics library for mac tsa cellar org the silent assassin writes rgc bcstec ca boeing com robert g carpenter writes can you please offer some recommendations it s really not that hard to do there are books out there which explain everything and the basic d functions translation rotation shading and hidden line removal are pretty easy i wrote a program in a few weeks witht he help of a book and would be happy to give you my source i think he wanted to avoid reinventing the wheel i would suggest that you take your code and submit it to comp sys mac binaries to be distributed including to the ftp sites many folks myself included would enjoy the extra code also quickdraw has a lot of d functions built in and think pascal can access them and i would expect that think c could as well if you can find out how to use the quickdraw graphics library it would be an excellent choice since it has a lot of stuff and is built into the mac so should be fast just to clarify the d routines that are mentioned in various places on the mac are in a libray not the rom of the mac a few years ago before i knew anything about implementing graphics i came across a demo of the apple grafsys d library and it actually did a lot however it is quite limited in the sense that it s a low level d library your code still has to plot individual points draw each line etc ad nauseum it has nothing on gl for example where you can handle objects other things to consider when talking about apple s old d grafsys library unsupported never was and no plans exist to do so in the future undocumented unless you call header files documentation if one knows something about graphics you could probably figure it out but i d assume there s better software available that gives better output and is at the same time programmatically nicer i e easier to program just my tax brent

applications robotics medical satellite engineering oil exploration etc it is called hips and deals with sequences of multiband images in the same way it deals with single images it has been growing since we first wrote it both by additions from us as well as a huge user contributed library feature description hips is a set of image processing modules which together provide a powerful suite of tools for those interested in research system development and teaching it handles sequences of images movies in precisely the same manner as single frames programs and subroutines have been developed for simple image transformations filtering convolution fourier and other transform processing edge detection and line drawing manipulation digital image compression and transmission methods noise generation and image statistics computation over such image transformation programs have been developed as a result almost any image processing task can be performed quickly and conveniently additionally hips allows users to easily integrate their own custom routines new users become effective using hips on their first day hips features images that are self documenting each image stored in the system contains a history of the transformations that have been applied to that image hips includes a small set of subroutines which primarily deals with a standardized image sequence header and a large library of image transformation tools in the form of unix filters it comes complete with source code on line manual pages and on line documentation host configuration requirements originally developed at new york university hips now represents one of the most extensive and flexible vision and image processing environments currently available it runs under the unix operating system it is modular and flexible provides automatic documentation of its actions and is almost entirely independent of special equipment hips is now in use on a variety of computers including vax and

general purpose packages i ve heard of besides what terramar has sips was written for aviris imagery i m not sure how general purpose it is you would have to contact goetz or one of his people and ask i have another piece of software pcw that does pc and walsh transformations with pseudocoloring and clustering and limited image modification you can compute an image using selected components i ve used it on megabyte aviris images without problems but for the best speed you need an external dsp card it will work without it but large images take quite a while times as long to process that s a freebie if you want it my favorite is idl interactive data language from research systems inc idl is in my opinion much better and infinitely easier its programming language is very strong and easy very pascal like it handles the number crunching very well also personally i like doing the number crunching with idl on the vax or mathematica igor or even excel on the mac if it s not too hairy then bringing it over to nih image for the imaging part i have yet to encounter any situation which that combination couldn t handle and the speed and ease of use compared to iraf was incredible by the way it s mostly astronomical image processing which i ve been doing this means image enhancement cleaning up bad lines pixels and some other traditional image processing routines then for example taking a

fortran compiler and sun s cgi libraries mindtool is a tool provided for the interactive graphic manipulation of molecules and atoms currently up to atoms may be input available via anonymous ftp at

nfotis gis geographical information systems software grass geographic resource analysis support system of the us army construction engineering research lab cerl it is a popular geographic and remote sensing image processing package many may think of grass as a geographic information system rather than an image processing package although it is reported to have significant image processing capabilities feature descriptions i use grass because it s public domain and can be obtained through the internet for free grass runs in unix and is written in c the source code can be obtained through an anonymous ftp from the office of grass integration you then compile the source code for your machine using scripts provided with grass i would recommend grass for someone who already has a workstation and is on a limited budget grass is not very user friendly compared to macintosh software a first review of overview documentation indicates that it looks useful and has some pixel resampling functions not in other packages plus good general purpose image enhancement routines fft kelly maurice at vexcel corp in boulder co is a primary user of grass this gentleman has used the grass software and developed multi spectral bands volumetric rendering full color on suns and stardents it was a really effective interface vexcel corp currently has a contract to map part of venus and convert the magellan radar data into contour maps you can call them at or email care of greg vexcel com host configuration requirements if you are willing to run a ux you could install grass on a macintosh which has significant image analysis and import capabilities for satellite data grass is public domain and can run on a high end pc under unix it is raster based has some image processing capability and can display vector data but analysis must be done in the raster environment i have used grass v on a sun workstation and found it easy to use it is best of course for data that are well represented in raster grid cell form availability cerl s office of grass integration ogi maintains an ftp server moon cecer army mil mail regarding this site should be addressed to grass ftp admin moon cecer army mil this location will be the new canonical source for grass software as well as bug fixes contributed sources documentation and other files this ftp server also supports dynamic compression and uncompression and tar archiving of files a feature attraction of the server is john parks grass tutorial because the manual is still in beta test stage john requests that people only

of gis software hardware microstation is a base graphics package that imager sits on top of imager is basically an image processing package with a heavy gis remote sensing flavor feature description basic geometry manipulations flip mirror rotate generalized affine rectification affine nd rd th and th order models as well as a projective model warp an image to a vector map or to another image rgb to ihs and ihs to rgb conversion principal component analysis classification k means and isodata fourier xforms forward filtering and reverse filters high pass low pass edge enhancing median generic complex histogram contrast control layer controller manages up to images at a time user can extract single bands from a band image or create color images by combining various individual bands etc the package is designed for a remote sensing application it can handle very large images and there is all kinds of other software available for gis applications host configuration requirements it runs on intergraph workstations a unix machine similar to a sun though there were rumors there are always rumors that the software would be ported to pc and possibly a sun environment pci a company called pci inc out of richmond hill ontario canada makes an array of software utilities for processing manipulation and use of remote sensing data in eight or ten different industry standard formats lgsowg bsq landsat and a couple of others whose titles i forget the software is available in versions for ms dos unix workstations among them hp sun and ibm and vms and quite possibly other platforms by now i use the vms version the pci software consists of several classes groups packages of utilities grouped by function but all operating on a common pci database disk file the tape i o package is a set of utility programs which read from the various remote sensing industry tape formats into or write those formats out from the pci database file this is the only package i use or know much about other packages can display data from the pci database to one or another of several pci supported third party color displays output numeric or bitmap representation of image data to an attached printer e g an epson type dot matrix graphics printer you might be more spe cifically interested in the mathematical operations package histo gram and fourier analysis equalization user specified operations e g multiply channel by add channel and store as channel and god only knows what all else there s a lot i don t have and don t use these so can t say much about them you only buy the packages your particular application interest calls for each utility is controlled by from one to eight parameters read from a common parameter file which must be in vms anyway in your default directory some utilities will share parameters and use the same parameter for a different purpose so it can get a bit confusing setting up a series of operations the standard pci environment contains a scripting language very similar to ibm pc basic but which allows you to automate the process of setting up parameters for a common complicated lengthy or difficult series of utility executions in vms i can also invoke utilities independently from a dcl command procedure there s also an optional programming library which allows you to write compiled language programs which can interface with read from write to the pci data structures database file parameter file the pci software is designed specifically for remote sensing images but requires such a level of operator expertise that once you reach the level where you can handle r s images you can figure out ways to handle a few other things as well for instance the tape i o package offers a utility for reading headerless multi band what adobe photoshop on the macintosh calls raw data from tape in a number of different interleave orders this turns out to be ideal for manipulating the graphic arts industry s ct t format would probably i haven t tried handle targa and so on above all however you have to know what you re doing or you can screw up to the nth degree and have to start over it s worth noting that the pci database file is designed to contain not only raster image data but vectors for overlaying map information entered via digitizing table land use and all manner of other information i observe that a remote sensing image tape often contains all manner of information about the spectral bands latitude longitude time date etc of the original satellite pass all of this can go into the pci database i believe that on workstations the built in display is used on vax systems other than workstations pci supports only a couple of specific third party display systems the name gould deanza seems to come to mind one of my personal workarounds was a display program which would display directly from a pci database file to a peritek vct q q bus bit directcolor display subsystem pci software could be overkill in your case it seems designed for the very high end applications users i e those for whom a mac pc largely doesn t suffice although as you know the gap is getting smaller all the time it s probably no coincidence that pci is located in canada a country which does a lot of its land resource management via remote sensing i believe the canadian government uses pci software for some of its work in these areas spam spectral analysis manager back in jpl developed something called spam spectral analysis manager which got a fair amount of use at the time that was designed for airborne imaging spectrometer imagery byte data pixels across by lines by bands a modified version has since been developed for aviris airborne visual and infrared imaging spectrometer which uses much larger images spam does none of these things rectification classification pc and ihs transformations filtering contrast enhancement overlays actually it does limited filtering and contrast enhancement stretching spam is aimed at spectral identification and clustering the original spam uses x or sunview to display the aviris version may require vicar an executive based on tae and may also require a frame buffer i can refer you to people if you re interested pcw requires x for display map ii among the mac gis systems map ii is distributed by john wiley clrview clrview is a dimensional visualization
