Abstract
When rendering a three-dimensional (3D) image, a render list is generated. The render list is sorted according to proximity to a notional camera, where each element of the render list specifies geometry and texture of a portion of the 3D image, and where at least two elements of the render list correspond to different levels of detail (LODs). The render list is then traversed twice: in the first instance, the render list is traversed to render each element in the render list to a respective texture, which includes applying a depth management technique to account for occlusion; in the second instance, the render list is traversed in a back-to-front order to render each of the textures to a display buffer to generate the 3D image, which includes applying an image space manipulation technique to at least some of the textures.
