WebtextureGather allows your shader to read the four samples that would have been used as part of creating a bilinearly filtered texel. Keep in mind tho it is used to access Single channels of textures. Basically it takes advantage of the fact that textures are stored and accessed in such a way that each channels data is stored together.

WebOpenGL provides a number of functions for accessing images through image variables. Image operations have "image coordinates", which serve the purpose of specifying where in an image that an access should take place. Image coordinates are different from texture coordinates in that image coordinates are always signed integers in texel space. golf pants for women on sale

Reading from a stencil-only texture is treated as reading from a one-component unsigned integer texture. So you must use usampler* types when accessing them, just as for accessing the stencil component of depth/stencil textures. Required formats health benefits no alcohol

"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.
