After clipping and division by w, depth coordinates range from -1 to 1, corresponding to the near and far clipping planes. glDepthRange specifies a linear … WebThe transform from NDC space to window space uses the current glDepthRange setting. That may be [0, 1], and that's what it is by default. But there's no rule that it must be. It can be anything you want, so long as both values are between 0 and 1. You can even reverse the near and far, using a range of [1, 0]. Share Improve this answer Follow mayor of ritzville wa https://cciwest.net
