Opengl depth mask
Web31 de out. de 2009 · I have the depth from my regular buffer shown quite well and a bit lower the depth map only buffer which shows nothing (white). I do draw the scene 2 times a frame (second time with no shader. Give the fact that the vert shader usually does nothing it should work the same). To set my buffer I used this: Webmask Bitwise OR of masks that indicate the buffers to be cleared. The three masks are GL_COLOR_BUFFER_BIT, GL_DEPTH_BUFFER_BIT, and GL_STENCIL_BUFFER_BIT. Description glClear sets the bitplane area of the window to values previously selected by glClearColor, glClearDepth, and glClearStencil.
