glDepthFuncGLLEQUAL
glDepthFuncGLLEQUAL is a constant used in OpenGL to specify the depth comparison function. When setting the depth function using glDepthFunc, GL_LEQUAL indicates that a fragment should be written to the depth buffer if its depth value is less than or equal to the current depth value in the buffer. This is a common setting for depth testing, allowing objects to be rendered correctly in front of or at the same depth as objects already drawn.
The depth buffer, also known as the Z-buffer, stores depth information for each pixel. When rendering a
In practice, using GL_LEQUAL is crucial for achieving correct occlusion in 3D scenes. If a scene contains
