texture-compression-bc-sliced-3d

The base BC feature allows compressed 2D textures and arrays. This additional feature allows BC formats on textures created with dimension: "3d", so a volume can remain compressed in GPU memory while being sampled with three-dimensional coordinates.

Volume visualization, voxel assets, and precomputed lighting volumes can use this to reduce texture storage and sampling bandwidth. Compression still uses two-dimensional BC blocks within each depth slice; it does not introduce a block format spanning multiple slices. Assets and uploads must follow the chosen format’s block layout and copy-alignment rules.

Check the sliced-3D token before requesting it at device creation. It depends on texture-compression-bc; the current specification enables dependencies implicitly, and explicitly requesting both supported features also makes the requirement clear. Without sliced-3D support, use an uncompressed 3D texture or a 2D texture array with shader code that handles interpolation between slices.
