WebIf you really want to, you can write code in your first-pass shader to manually output stuff like depth, to a separate colour texture attachment in your FBO. That would be for use by you in your post-pass shaders. For OpenGL's use in its internal depth-testing, you would additionally need either an RBO or texture set as your FBO's GL_DEPTH ...

Web9 de nov. de 2014 · I’m very new to GLSL coding, so I might be making an elementary mistake here, but I’m using fragment shaders to get a depth map (actually several depth maps, for two-step depth peeling and shadow mapping), but the shadow maps are coming out as either pure max depth, or pure min depth. Here’s where I set up the framebuffers: … 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.
