Web10 de out. de 2008 · That would wind up with a depth of 0.48, which isn’t the depth of anything you rendered into that pixel. If you were to render something on your post-blit depth buffer with depth 0.49, it would overwrite the color, which makes no sense in terms of what you originally rendered. Web1. Depth buffer values are clamped to that range because usually they are using fixed-point representation, so if clipping is disabled (by glEnable (GL_DEPTH_CLAMP)) then they can't hold anything beyond that range. However, there isn't really a good reason for this clamping when floating point depth buffers are used. Web15 de jul. de 2015 · OpenGL by default assumes a [-1, 1] post-projection depth range.
