Yves, I remember the old radiosity that created a bitmap that was decaled on the surfaces. That one did not account for the color of bounced light. That one is gone.
But we still have the new radioisty called "Radiosity"
I think this is what you are calling "The current Global Illumination." I don't remember it ever begin called that previously, however.
By "Global Illumination" I meant the "Global Ambiance" above "radiosity" which does use a map to color the ambient light and is what you are calling " Image Based Lighting"
Fuchur, can you show an example of this...
Not sharp?
