Sounds like you need the Doom or Duke Nukem engine.

Seriously: google on VRML for a possible approach, but 40,000 points???On 6/9/05, Brian Weeden <[EMAIL PROTECTED]

Mathematica has an API.

There are also a bunch of 3d plotters on www.codeproject.com like:  (just 
did a search for "3d plot")

I have need of a plotting function/program/library for some code I am
writing for a master's paper.  Essentially, I am writing a C program
that will output an object's position in an x,y,z coordinate system.
I need to show that visually somehow.  I was originally using just x,y
coords and dumping the data file into Excel.  However, Excel has a
limit on the number of points it can plot (like 40,000 or something)
and I will be generating more.

Having it display the object's position in the 3 axes in real time as
the program is running and calculating the points would be great.
Displaying all the points at the end to show how the objects moved
over the time period is a must.

My programming skills are fairly limited (took 1 class in C 10 years

Well I'm doing orbit predictions.  Normally that involves differential
equations which I am solving numerically - calculate all the change in
acceleration/velocity/position for a point, move a timestep, repeat. 
With the simulation running into years of time with a timestep in
minutes, that can get quite large.

Kewl !   

The first time I wrote that program was in FORTRAN in 1972.

I think I even wrote it in COBOL once.  (don't ask)

Always made me shrarpen up my trig!

That's alright I'm no good at spelling "sharpen" either but I
still remember a²+
b² =
c². ;-)
