Silhouette Maps for Improved Texture Magnification

 Slide 2 of 61 [index] [first] [prev] [next]  

We start our journey through time back in 1992, with the advent of Wolfenstein3D by id. This was one of the first 3D games to feature textured surfaces.

Here we have an actual screenshot from the game, taken as our character approaches a textured wall. We can see the rendering engine is doing simple point sampling into the texture array. During this talk, we will call this the "nearest-neighbor" sampling approach. This is fast, but results in the pixelated appearance shown here.
