I am not sure if there is a word for what I am trying to do. What I am trying to do is to map a texture on a rectangular plane (which works). But I want to be the texture and the plane to be partly transparent to form randomly formed objects.
I think that I could use the alpha value to do this.
But how do I generate and store the alpha values for existing textures. Are there any simple examples for this? Or is there perhaps a better way to do this?
Thank you for all replies,
