The Depth Buffer holds the "depth" of the pixel in the scene. When OpenGL renders your geometry, each fragment (pixel) is compared against the depth buffer's value at that point. If that fragment has a z value lower than the one in the buffer, it becomes the new lowest value, and thus the pixel to be rendered.

Web25 de abr. de 2014 · You know the default output from a depth texture is already: vec4 (r, r, r, 1.0), right? You can just write FragColor = texture (uDepthTex, TexCoord0);. As for the rest of the situation, the GLSL shader's not going to help explain this - the code where you setup your depth buffer, projection matrix, FBO, etc. is actually more relevant. Web2 Answers. You can use Framebuffer Object (fbo) to render the depth values into texture.
