. Started a volumetric effect to test transmittance maps & composition with transparent FXs
. First attempt at transmittance DCT encoding (not working) (debugging now)
. DCT Test App is working
. Attempting to use that in shader...
. Finished displaying the volume
. Transmittance map is not working
 => I'm thinking about encoding ZMin/Max for the transmittance interval because I believe it's necessary: you can't simply walk into Mordor...
 => No, you can't simply walk into the volume at any position and start encoding anywhere: you must encode all the way or nothing. Except the shadow volume starts pretty much anywhere and we'd lack precision if we kept the shadow integral constant.
 => So finally, I'll store 6 DCT coefficients and 2 Z values for in & out
. Finally working great !
 => Still get some artifacts here and there when the volume slice is thin
. Now delving into long awaited optimization!!!!
