How to use transparency?
This is a basic question: I just want to enable the transparency of the 3D object with RGBA colors and not texture. I used blending and followed Learning WebGL Lessons 8 http://learningwebgl.com/blog/?p=859
but found that I can't make it work with RGBA color. Some objects that have alpha value as 1 and are in front of others, are still seem as transparent objects.
I think since I disabled depth testing, I need to draw the objects in the order that how they cover the others. But is there anyway I can simply draw them without considering the order and just show the objects with alpha value less than 1 as transparent? Thank you very much!
