Opengl texture gather
WebWhen texturing a mesh, you need a way to tell to OpenGL which part of the image has to be used for each triangle. This is done with UV coordinates. Each vertex can have, on top of its position, a couple of floats, U and V. … 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.

The only problem is: When using Windows 7 there is always OpenGL used (as the newest DirectX version don't work with Win7). When using Windows 10 I can selecht between DirectX and OpenGL.
WebStencil formats can only be used for Textures if OpenGL 4.4 or ARB_texture_stencil8 is available. 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 WebTexture Swizzle.
