This way OpenGL is still able to do early depth …

WebPerform the draw call (s). If updating and drawing: Bind the VAO, VBO, IBO; Update the buffers (updating vertex atributes is only necessary if the vertex format has changed); Perform the draw call (s). Optionally unbind to avoid accidental modification of the buffers and VAO. That's as simple as that. This order of operations should function ... WebAug 28, 2024 · In OpenGL, to perform a multisample resolve, you use a blit operation from a multisampled framebuffer to a single-sampled one. Note that such a resolve blit operation cannot also rescale the image or change its format.
