Opengl depth texture
WebTextures are typically used for images to decorate 3D models, but in reality they can be used to store many different kinds of data. It's possible to have 1D, 2D and even 3D textures, which can be used to store bulk data on the GPU. An example of another use for textures is storing terrain information. Web1 de jul. de 2024 · Summary In the last tutorial I explained how to do very simple postprocessing effects. One important tool to do more advanced effects is access to the depth buffer. It’s a texture in which the distance of pixels from the camera is saved in. To understand how postprocessing effects with access to the depth buffer work it’s best to …

The reason for sharing the texture is that my question was actually simplified compared to reality: it's actually a depth-stencil buffer, since I need to share the stencil buffer between two framebuffers while the second reads depth values from the first.
