WebThe Default Framebuffer may have a depth buffer, and user-defined framebuffers can attach depth formatted images (either depth/stencil or depth-only) to the GL_DEPTH_ATTACHMENT attachment point. If the current framebuffer has no depth buffer, then the depth test behaves as if it is always disabled. Fragment depth value WebEnabling depth buffering. In order to use depth buffering, the following must occur:. The current framebuffer, whether an FBO or the default framebuffer, must have a depth buffer. Depth testing must be enabled. This is done by calling glEnable (GL_DEPTH_TEST). By default, depth testing is disabled when you create the GL context. dyson charging cable model 17530-02
