How should I set the sizing parameters in DirectX to make particles size the same way as other three-dimensional objects (i.e. get bigger closer and smaller farther away)? I know what each of the three sizing parameters (A, B, and C) are supposed to do, but what are reasonable values for them? I have copied the values from several demos, but my particles never seem to size correctly with camera distance. Specifically, the particles become very small when the viewer is close to them, and quickly grow to a maximum size as the viewer moves away from them. I set the sizing parameters to the same values used in the CodeSampler point sprite demo. Any help is greayly apprecitated. [Edited by - janoside on April 20, 2006 4:52:27 PM]
