Where can you find source code of heap sort in OpenGL?

Heap sort is not directly related to OpenGL, as it is a sorting algorithm rather than a graphics API. However, you can find implementations of heap sort in various programming languages on platforms like GitHub or in educational resources about algorithms. If you're looking for sorting within an OpenGL context (e.g., sorting vertices or pixels), you may find relevant code snippets or examples in OpenGL tutorials or graphics programming books that implement sorting algorithms.
