Hello everyone here~
I am working with CGFX Shader. In my project, I used 3D points dataset. I’ve implemented CGGX Shader on 3d points to have the Point Size Attenuation effect. In my CGFX shader I found: ‘PointDistanceAttenuation = float3(1.0, 0, 0);’ in ‘Renderstates of Vertex Pipeline’
I’ve tried with PointDistanceAttenuation = float3(0,1.0,0) to have a linear point size attenuation, but it doesn’t work, all the points look like in a same size.
Actually, the 3D points which are far away should look smaller than those closer to the viewer.
–How to active PointDistanceAttenuation property in CGFX shader?
–or before activation of PointDistanceAttenuation I have to enable other states?
–PointDistanceAttnuation is used to set PointSize? or Point lighting?
Thx in advance~
