Subject: [Algorithms] Making an object transparent in openGL
I would like to make a 3d rendered object transparent acording to a global factor. Imagine a cube. It is completely black while rendering. Now I set my material/shader (call it as you whish) to a transparency factor of 0.5 anf then the cube "bends" with the background image. What openGL calls do I have to do to make this happen? In a software renderer this sounds pretty simple, but I dunno how to accomplish this prob in openGL...
Thanx... maybe is a very simple question...
