Xfig?  That's a drawing program, sorta like MacDraw.

Maybe you mean Xgraph.  It does an okay job until you start getting
down to very small subareas of the graph and then it sort of loses its
brains, but it is pretty clever and sensible, otherwise.

Xmgr is supposed to be pretty nifty but it requires Motif.  Someone,
I'm sure, will correct me if I'm mistaken, but I believe that there's
also an OpenLook version available (Xvgr???).  I believe it does a
good job with tick marks.

My recollection is that gnuplot is all right, too.

I mean, it's pretty darn easy to write an intelligent tick mark
algorithm -- I've done it a couple of times.

Date: 21 Nov 92 23:31:36 GMT

Last time I checked (probably Alias 3.1, I doubt it has changed since
then), Alias computed stereo views incorrectly, by rotating around the
object instead of keeping the camera axes for the two images parallel,
or by "toeing in" the cameras while moving them horizontally.

You can confirm this observation by increasing the disparity of the
views (increasing the distance or baseline between the cameras) and
looking at the images.  The results in extreme are "undistorted" left
and right side views of the object; the correct image would appear
significantly stretched horizontally.

Correct stereo pair rendering requires some SDL hacking, changing
camera location and the pixel limits of the output views.

The literature contains many ways of generating patchwise surfaces for both 
gridded data and scattered data.  The major trick is to make the slopes of the
patches match, and this is especially difficult if the patches are irregular.

Yes, subset selection is extremely difficult for scattered data.  Using either a
fixed number of data or all the data within a fixed area can lead to excess or
insufficient data for a given patch if data density is uneven or anisotropic.
Second order natural neighbor subsets are the only subsets, that I am aware of,
which will overcome this problem.  However, given such subsets, one cannot use 
any of the usual spline patches because of slope discontinuities at the edges
of the patches; natural neighbor interpolation can be used to generate a surface
with a continuous slope.

I was recently looking at a meshed model of a skull when I realized
that the equation that I've been using for shading (let's say, there is only 
ONE light situated at the eye point pointing away towards the screen)
has trouble when the surface normals of the polygonal patches
do NOT show a great variation. (Since this angle stays relatively
constant throughout the surface, the entire surface looks pretty
much the same color).

What I've been wondering is that has anyone looked at ways of
improving the dynamic range of intensities in an image based on
the range of surface normal variation locally?

Now, I know that as I move my eye close in, this variation becomes
larger and hence the surface detail becomes more apparent, but what
I want is the shading to stay relatively unchanged as the eye moves
around.

industry.  The following positions are currently available at the Research 
Assistant I or II level:

    Scientific Visualization:  Responsibilities include developing new
        scientific visualization methods and paradigms, such as vector field 
        visualization and concurrent visualization of field simulation 
        results.  An MS is required. 

    Computer Graphics:  Responsibilities include development, instruction, 
        support, and maintenance of interactive graphics software for internal 
        and external users.  Knowledge of X/Motif and GL is required.  A BS is 
        require, MS preferred.

    Programmer:  Responsibilities include development, maintenance and support 
        of general software systems.  A strong background in software 
        engineering, complex data-structures, algorithms, and C is preferred.  
        A BS is required.

Demonstrated ability and experience in programming and testing on high-
performance graphics workstations in C and UNIX is required, and a working 
knowledge of FORTRAN is preferred.  Travel may be required in each position.  
Salary is competitive and commensurate with degree and experience.  The Center 
also offers the opportunity for further graduate study  in computational 
engineering, computer engineering, computer science, and various traditional 
engineering studies.

Interested persons should submit a complete resume, including details of 
relevant interests, expertise, and experience, along with names and addresses 
of three references to

    Dr. Joe F. Thompson, Director
    NSF Engineering Research Center for Computational Field Simulation
    P.O. Box 6176
