    Shader depth

    \$\begingroup\$ Don't output depth unless your shader absolutely needs to! Most graphics cards do two depth culling passes, "early-Z" and "late-Z". If your shader doesn't write depth, the GPU can do "early-Z", which means that if the fragment is behind something or won't be shown, it can skip a lot of processing and never even run your shader.

    Shader Depth Output SV_Depth. Fragments usually control their depth from the mesh, based on the interpolated values during rasterisation (between the vertex and fragment shader, turning the geometry into fragments/pixels). However it is also possible for the fragment shader to override the depth values that will be written into the depth buffer.

You don’t update the depth value in the fragment shader; in fact, the fragment shader can be empty, i.e. just. void main () {} So long as the FBO has a valid depth attachment and you haven’t disabled depth writes via glDepthMask, the depth will automatically be written to the depth attachment. The focus of these chapters are on Modern OpenGL. Learning (and using) modern OpenGL requires a strong knowledge of graphics programming and how OpenGL operates under the hood to really get the best of your experience. So we will start by discussing core graphics aspects, how OpenGL actually draws pixels to your screen, and how we can leverage .... Feel free to experiment with these values. Note that we use a depth texture, not a depth renderbuffer, since we’ll need to sample it later. // The framebuffer, which regroups 0, 1, or more textures, and 0 or 1 depth buffer. Implementing a Fast Geometry Shader on the C++ side is similar to shaders in UE4.

    A restriction on the fragment shader for early depth testing is that you shouldn't write to the fragment's depth value.

In particular, using depth texture in an Image Effect often needs special handling on Direct3D + Anti-Aliasing. In some cases, the depth texture might come directly from the native Z buffer. If you see artifacts in your depth texture, make sure that the shaders that use it do not write into the Z buffer (use ZWrite Off). Shader variables.

    The vertex shader is calculating the clip space position (a 4 dimensional version of screen space & depth) of each vertex of the mesh. Sets of three vertices are used by the GPU to calculate the screen area the mesh’s triangles cover. The GPU then runs the fragment shader for the pixels the triangle covers, passing along the interpolated data. Use depth in shaders Parse depth information for the current frame.
