Well.  Consider that a 486 motherboard (assuming that you upgrade from a 
lower technology) would only cost a user $1K or lower for a 66Mhz Local 
Bus with a 24bit video card.  How much would it cost to upgrade a Mac?

Actually, it's more like $25-30K for a real healthy SGI, but at least you

Subject: HELP:  Hexagon tiling problem
Organization: University of Illinois at Chicago
Date: Tue, 15 Dec 1992 00:30:38 GMT

	I don't think the answer to this is in the FAQ, and I browsed
Graphic Gems III (I can't find the lab's copy of I and II) but I doubt the
answer is there, either.

	Given a plane tiled with hexagons and a point (x,y) on the plane,
how do I find the point corresponding to the center of the hexagon that the
given point lies in.

	Although my use for this function is a little more esoteric, it could
be used to do a "hexagonal pixellation," which would be funky looking.
	I've tried solving this problem a few different ways.  The most do-able
is to fmod() the whole space into a rectangle two units high and three wide,
and then to partition x into four regions:  the first region corresponds to
a whole hex, the third goes either up or down, and for the second and fourth
you check if the point lies above, below, or between the two angled segments.
This seems somewhat inelegant, however, and I suspect there's a more direct
way to do it.
	Since I know the slopes of the lines connecting the centers, I tried
using y=mx+b, solving for b, then rounding b off to the nearest unit, for 
both angles (sqrt(3) and -sqrt(3)), and then finding the intersection. 
However, I ended up with rhombuses.
	Suggestions?  Is this in one of the Gems? Help!

If I were to buy 3D Studio 2.0, what kind of output options do I get?
Does it only render to files (TGA, etc) and FLI's (or FLC's) ?

Do you have to create the FLIs after creating the individual bitmaps, or
does the system do that for you?

Oh. On a similar topic. I saw someone before ask for the FLC (not FLI)
format, and people responded telling where to get the FLI format. My
question is: is the FLC (NOT FLI) format available, and where can I get it?
Is there a public domain FLC player available?

Inquiring minds want to know.

Its possible that your machine is paging because 
the arena has become fragmented.  For example, a lattice
might be allocated on several pages (a uniform lattice consists of 7 chunks
of memory, 8 for perimeter and curvilinear).  

If your loop controller doesn't wait for a completion signal from
Render, then you could be filling memory with slices that are waiting
to be processed, and that could also cause paging.  You should loop a
'done' signal upstream to your controller.  Because of a bug,
this only works if you use a widget parameter.

As for the order of execution:  there is a problem with the firing
algorithm that you may be seeing if you are buffering a lot of data.
If the flow of data splits into two streams, then is joined into two 
ports of single module, and one stream is much faster than the other,
the data streams will get out of sync.  If you use upstream control to
regulate the flow, then this won't be as much of a problem.

No, no, no.  Allocate a lattice using cxLat*New(), put it on the
output port with cxOutputDataSet(), and then you can forget about it.
The system will take care of manipulating the reference count to
reclaim the memory when downstream modules are done with it.  If you
wish to have data persist, increment its reference count with
cxDataRefInc().  When you are done, decrement the count with
cxDataRefDec().  You should never, ever use cxDataFree, as it may free
something that another module is using.  See the Module Writer's Guide, 
Appendix B.3 for more information.

Have you made sure to hit carriage return when you typed in the
increment values? I noticed that you can type values explicitly into
the sliders, but they don't fire the module until you hit a carriage
return, so the previous value is still used by the module.

OK, I've minimized my module sizes, and thought I'd post a summary for
other module builders (sorry if y'all went through this before I was
an Explorer user...)

First, I did like Robert Skinner said, and set the CXBUILDSHARED 
environment variable. That knocked my modules from at least 2 MBytes
to about 600 kBytes.

Then I stripped the modules, (from my colleague Ram Rajagopolan) and that 
gets 'em down to the 160 kbyte area, which I'm satisfied with.

Thanks Ram and Robert.

Explorer \is/ written to have things come up right, but we put
a lot of geometry and font information in a subdirectory of the
/usr/lib/X11/app-defaults file, based on screen size.  If you
don't follow the default SGI login procedure, you must type

	setenv XUSERFILESEARCHPATH `appdefpath`

This is described in the release notes, section 2.3.1.  If you don't
have this defined correctly, you get gray windows that you must position
manually, and the font is too big.  If it is correct, the windows have
blue-green backgrounds and reasonably fonts, and pop up in predetermined
places.

We do have other brands of machines, with AVS and many other tools which I

Subject: Render grows indefinitely
Organization: Exxon Research & Engineering Co.
Date: Mon, 14 Dec 1992 21:24:33 GMT

After running out of memory a few times, I watched the process sizes
with the "top" command to see which modules in my map were taking up
more memory.

Each time I looped through my map, Render got a little bigger. My map
repeatedly sends geometry to the Render module via the same output-input
wire. Render is smart enough to delete the old geometry from the screen,
but not apparently from memory. Gradually it just keeps growing until
I'm paging so hard I can't even CNTRL-C out of the program, and usually
end up at the Reset button.

This looks like a job for an SGI person with access to the Render source.
Are you there? Can we fix this? 

I hope either 1) I can get this fixed without having to wait for 2.0, or
              2) It's fixed in 2.0 and 2.0 is in the mail right now.

Any suggestions? Any way I can work around it? Thanks

If it returns a NULL, then no data has been received (and there is no 
type).  I'll make sure that cxParamStrGet is fixed, but if there's no 
data, it will probably return a NULL.

I have noticed other memory leak behavior in some modules.  This
is a problem SGI will hopefully track down (using CASEVision ??)

I've been in on this newsgroup for two weeks now, have a ton of
questions, and want to know what the heck is going on...

Where's the FAQ posting ?

 ... or where's the FAQ ftp site
directory etc.


Inquiring minds want to know.
