So.... I have a short movie (.mov file) that i am breaking up into a pixel grid. Each pixel is drawn as a rectangle, with each rectangle having a z location (and size) based on it's colors brightness level.
Everything was working fine in 2.05b... each new frame would draw on top of the the previous frame. So all the z locations, of each rectangle, were relative to only the current frame being drawn, above the previous frames. This is how I want it.
Now however, in 2.06b, the z-locations are relative to every rectangle on screen, regardless of whether they are in the current or previous frames. So a rectangle being drawn in the current frame with a z location of 100, would be drawn underneath a rectangle in a previous frame with a z location greater than 100. This is not what I want.
I do not want to clear the background at the end of each draw cycle, because of the demands of what i'm trying to accomplish.
Any idea on how to work through this?
