WebDefault Framebuffer. The Default Framebuffer is the Framebuffer that OpenGL is created with. It is created along with the OpenGL Context. Like Framebuffer Objects, the default framebuffer is a series of images. Unlike FBOs, one of these images usually represents what you actually see on some part of your screen. WebOpenGL Rendering Pipeline. The Depth Test is a per-sample processing operation performed after the Fragment Shader (and sometimes before ). The Fragment 's output depth value may be tested against the depth of the sample being written to. If the test fails, the fragment is discarded. If the test passes, the depth buffer will be updated with the ...
