WebWrite to the output texture; Step 1 is the key here. In the pixel shader version, the source image is sampled multiple times per pixel. In the compute shader version, each source texel is read only once inside a work group. Texture reads usually use a tile-based cache, but this cache is still much slower than shared memory. WebA texture is an OpenGL Object that contains one or more images that all have the same image format. A texture can be used in two ways: it can be the source of a texture access from a Shader, or it can be used as a render target.
