GM Per-Pixel Bumpmapping

Posted by Adventus on May 3, 2007, 9:48 p.m.

Yea i did it, and pretty fast too…. You can check out the GMC topic (and get the source) here:

L3S_Bumpmapping

It basically works by spliting the Dot3 blendmode into 3 seperate multiplies & add passes, although theres alot more to it than that. And yes this is true perpixel bumpmapping, just the same as you'll see in modern games, i really cant find any flaws in it. Using some wizardry i managed to get it to work without additional surfaces and only 2 additional sprite renders. I should really thank OpticalLiam for getting me interested in GM lighting again.

In other new, my fancies have wandered and i've begun making the shift from GM to C++. To ease the transition i've started using Ogre3d and inspired by Toon-Master i've begun making a GM framework. Im in limbo whether i should finish Tribal before i move on…. what do you guys think?

Cheers,

Y'know, I've had a similar method in place for … a year now… in EotS.

Good job just the same.
