Web26 de mai. de 2016 · But i need the Depth-Test to be calculated before the fragment shader executes and i dont know how i can specify this in the shader. I dont understand what the Vulkan Documentation means: An explicit control is provided to allow fragment shaders to enable early fragment tests. Web22 de jan. de 2004 · Early depth means that the depth buffer is updated before the “texkill” is executed. This means if the fragment passes the Z test, but fails the “texkill” then the depth buffer will contain the wrong data if early Z is enabled. You must perform “texkill” and alpha test before depth test as shown in the OpenGL pipeline.
