Each object has its own unique position.  The grid is calculated to get the
x,y.  I tell the display how long each row is and it plots each object on
rows and columns.  It is actually plotting in circles as it moves down a
group of rows at a time.  Color is determined by what the objects are doing.
I will look at OpenGL.

 

Thanks,

 

Ron

It's difficult to understand your needs.  Is your data laid out in a grid?
Can you have multiple objects with the same positions?

 

Depending on what you're trying to do, it might make sense to render them
using OpenGL.

Hello all,

 

I need to build something that shows the interaction of about 100,000
objects.  The objects need to display by position and color.  I have x,y
positions and colors programmed.  What is the best way to display these
items? 

 

I saw some of the simulation programs, and that looks like that may be what
I need.  If you have some tips for hooking the simulations up to my objects
please let me know.

 

I tried just turning on and off single pixels but the result was too small.
I could do some math and turn on more then one pixel to make the display
larger but I thought I'd ask if anyone had some ideas for a better way to do
this.

 

Thanks,
