Carmack on 3D: May as well be speaking alien

By Kieron Gillen on March 14th, 2008.

So, you're saying graphicsability will be improveitudes

While I understand about one word in forty, I do like hearing Carmack speak about what he’s been up to. His recent interview with PC Perspective is a goldmine of Carmack-thinking. For example, this is what Carmack’s been up to recently…

“It involves ray tracing into a sparse voxel octree which is essentially a geometric evolution of the mega-texture technologies that we’re doing today for uniquely texturing entire worlds. It’s clear that what we want to do in the following generation is have unique geometry down to the equivalent of the texel across everything. There are different approaches that you could wind up and try to get that done that would involve tessellation and different levels of triangle meshes and you can could conceivably make something like that work but rasterization architecture does really start falling apart when your typical triangle size is less than one pixel.”

I empathise. When triangle size gets less than one pixel around here, it’s complete chaos. Jim starts screaming, Walker just flakes out completely and it’s only Alec who keeps his head together, reassuring us that triangle size will be back at more than a pixel shortly. However, I have managed to decode some stuff.
