Web15 feb. 2008 · Noisy textures like grass and stucco can be used with indirection mapped (which is convenient when texturing terrain.) We pre-warp structured textures by the inverse of the indirection map to maintain their appearance. Our process gives approximately uniform texture resolution on all surfaces. WebAt runtime, when SVT samples a texture, it does the following: It samples an indirection texture, calculates the non-virtual UVs, and samples a cache texture with these UVs. It translates the virtual UVs to a tile ID, and binds an additional render target that …

The Page Indirection texture is a texture with one pixel for each page/tile in the virtual texture, that will map the incoming UVs to the Page Table cache texture that has the actual texel data. This texture can get quite large, so it must use some compact format, like RGBA 8:8:8:8 or RGB 5:6:5.
