We are planning to buy a remote, 6D tracking device in our lab in the
near future. We have narrowed the field down to two:

	1. Polhemus Fastrak system, and
	2. Ascension "Floock of Birds" system

Does anyone on the net have experience with either/both of these
systems and if so what is your opinions on them? How do they compare, etc?

Any feedback from experienced users will be appreciated.

Thank you.

Hello, everybody,

This is first time I come to this news group. I am currently
looking for math library which can perform most common math
operations such matrix inversion, etc..  The library is
going to be used on PCs and with Turbo C programs. To
accompany the C program and to present the results, I also
looking for library which can plot the output data. Again,
the plot library will be on PCs and with Turbo C compiler.

Your suggestions as for the names of the packages and the

I am forwarding the query of my friend who has no facility to post it.
----------------------------------------------------------------------
Hello,
I am looking for a kind of an algorithm/implementation(preferably in C)
for projections of surfaces. My problem is specific. What I will have is
a 2-d parameters plane(horizontal) and a surface passing through points
on a (vertical) axis,Z.  Thus I will be dealing with the R^3 space. Is
there any implementation to get the projection of such a surface on the
parameters plane when viewed along the Z-axis?
one can expect the surface to have multiple extremal points which should
be projected as a single point.
Any help would be greatly appreciated.
Please mail your response to me at anoop@cc.iitb.ernet.in

Your method's normally the most efficient overall, too (though you could do
extra things like putting the polygon in a bounding box and using the box for
tests, if the polygon was sufficiently complicated).

You don't need to rotate:  just throw away one of the coordinates of the
triplet (this is equivalent to casting the polygon onto one of the XY, YZ, or
XZ planes.  The best coordinate to throw out is the one with the maximum
absolute value for the normal components of the plane.  For example, if the
plane's normal was (-1,-5,2), throw away the Y component (i.e. use the XZ
plane for casting).  This ensures that you don't cast the polygon onto a plane
perpendicular to its normal, which turns the polygon into a no-area beastie.

Subject: Question about Graphics cards and GUI OS's...
Date: 10 Sep 92 22:17:35 GMT

Many graphics cards offer different amount of colors at different resolutions.
Say   640*480*16.7mil
      1024*758*256
      800*600*65K

Now if I was using a GUI operating system like OS/2, and set the system to one
resolution, say the highest one of 1024*758*256. Now if I want to see graphics
with 16.7mil colors, do I have to reconfig the system for the proper
resolution & reboot, or will the system open a 640*480*16.7mil window???

It seems rather silly to have to reconfig and reboot in order to see more
colors.

This may be simpler than you realise, I had almost forgotten this.
I think for any polygon, or even polyhedron in 3D, all you have to
do is average all the points to get the centroid.

So in the case of a triangle, it would be : A + B + C
                                           -----------
                                                3
or more efficiently (A + B + C) *  1/3.
Store 1/3 as a constant, ie 0.333333333, then the operation is just
a multiply.
Pseudocoded it would be something like this :

Somewhere in beginning of program or constant declaration ...
oneThird = 0.3333333333

Later ...
cx = (x1 + x2 + x3) * oneThird
cy = (y1 + y2 + y3) * oneThird

Storing 1/3 as a constant could be a time saver because it is used
twice. That makes the algorithm 6 additions and 2 multiplies.
Shortening the constant to 0.33 or 0.3 may even speed up the
multiplies depending on your accuracy needs, I'm not sure.

Has anyone else found anything better ?

Hope this helps,

Hi!

Does anyone know of a good algorithm for drawing 3D bitmap polygons?
If you've seen 'Operation Wolf 3D', you know exactly what I'm talking
about! In case you haven't, I'll try to describe it;

You are walking through corridors and rooms, and all the walls are
consisting of bitmap pictures, ie Hitler portraits and brick walls.

It's all in real time, and the animation is lightning fast. The
resolution of the bitmaps isn't that great, but definitly good enough
if you can do it at that speed. There are far too many pictures, for
them to have been predefined in memory at all different angles and distances.

Any ideas, anyone?

I'm attempting to move some data from .DXF files (autocad on the PC) to 
SIP under UNIX - does anybody know where I can find a program that would
let me do that?
