Abstract: 3D culling techniques are well established to improve rendering performance, but cannot be applied to 2D games in which the scene is composed of partially transparent textures in a known layer arrangement. Commonly, 2D rendering is achieved in a simple back-to-front blending scheme. This paper discusses options to realize 2D occlusion culling techniques using standard OpenGL functionalities, and introduces a novel 2D culling technique based on min-max mipmaps. We evaluate the performance of the different techniques for different scenarios.
