If you only have a single mipmap level and you want nearest filtering then this is a more efficient lookup than a texture () call. No helper thread is needed, no sampler descriptor is needed, and no coordinate calculation is needed, all of which improve energy efficiency.

texelFetch - perform a lookup of a single texel within a texture

Web20 Aug 2024 · The data format returned is determined by the texture format. For example, if the texture resource was defined with the DXGI_FORMAT_A8B8G8R8_UNORM_SRGB format, the sampling operation converts sampled texels from gamma 2.0 to 1.0, filter, and writes the result as a floating-point value in the range [0..1]. Related topics. Texture-Object Web25 Dec 2011 · Now what happens is, that the texelFetch () in step 3 returns bulls**t. But if I reverse the order in step 3 and bind the depth texture to texture unit 0 and the color texture to texture unit 1 while fetching the color from u_Texture1 and the depth value from u_Texture0, then everything is cool. In this case the textelFetch returns correct values.
