Tracking 3D objects to pixels value.?
I'm posting this to raise a question, as I am tackle one right now.
My co-worker asked me if I can give them the pixel coordinates of objects appear on screen. I've try to research, but seems it is not easy.
To explain my situation better, lets say I've rendered out a car that move from left to right of the screen. I can easily take out the x, y, z coordination from 3ds max. However what I need is a 2D coordinate of x and y of, say, the pivot of the car that appear. (say it will go from x=0,y=300 to x=1024, y=300) (Not 3d x y z )
Is there any way to export that information frame by frame straight from 3Ds max? Is there any script written? Or is there another way to do it around?
Thank you friends and good luck.
