구문

type TextureElem = 'f32' | 'u32' | 'i32';

설명

All three are core in both targets.

An integer texture is unfilterable: interpolating integer texels is undefined, and WGSL rejects textureSample on a texture_2d<u32>. GLSL would accept texture(usampler2D, …) with nearest filtering, but a construct that compiles on WebGL2 and cannot be expressed on WebGPU is what authoring once for both targets is meant to rule out. Read an integer texture with textureLoad, textureDimensions and textureNumLayers; textureSample and textureSampleLevel on an integer key are tsc errors.
