Efficent method for movement?
Dec 28th, 2009, 11:23am  
In my program, I'm trying to get many points to corkscrew (or randomly progress) around a line from one end of the line to the other. (something like http://xconst.freeshell.org/applets/ribonkit/)  Not an extremely difficult task I guess... but I want to have several hundred thousand points and tens of thousands of lines.  So I have to do it extremely efficiently.  The lines are easy enough... they're static.  I load them into a VBO and call that in the draw.

Is there any way to tell the video card, move these 100,000 points from A to B (in a fluid manner), without having to calculate the new position and send it all to the video card again on each draw

I've never done it, and I don't know if you can do it from Java, but this can probably be achieved with a vertex shader.
