Anatomy of a Texture
Summary
An in-depth walk-through of texture memory layouts and platform-specific nuances for 1024x1024 RGBA textures using BC7 as the example. The article covers block compression, texel ordering, mips, and tiles, and explains debugging challenges and practical tricks for diagnosing texture address computations. It also discusses non-contiguous textures, mip tails, and the importance of memory layout for performance and portability across platforms.
