Opengl depth texture
WebShadow samplers. If a texture has a depth or depth-stencil image format and has the depth comparison activated, it cannot be used with a normal sampler.Attempting to do so results in undefined behavior. Such textures must be used with a shadow sampler. This type changes the texture lookup functions (see below), adding an additional component … Web19 de fev. de 2012 · This is a depth texture.

I’ve recently started work on a game engine, but I’ve run into a slight hiccup - I cannot get my fragment shader to read a depth texture. Just to be clear, the fragment shader can read from color textures and the depth texture itself is working - I verified that with glReadPixels - but the fragmentShader just won’t read the depth data. …
