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. WebRenderbuffer objects were introduced to OpenGL after textures as a possible type of framebuffer attachment, Just like a texture image, a renderbuffer object is an actual buffer e.g. an array of bytes, ...

Web10 de nov. de 2024 · The effective internal format specified for the texture arrays is a sized internal depth or depth and stencil format (see table 8.11), and the value of TEXTURE_COMPARE_MODE is NONE. My understanding of that is that in OpenGL ES 3.2 depth textures are not filterable. Maybe I'm not finding it but I don't see any … 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 ...
