Abstract: In graphics processing data is received representing one or more vertices for a scene in a virtual space. A projection of the vertices onto a screen space of a display device is performed. A density of the vertices is adjusted for selected portions of the screen space, such that a lower density of vertices is present in selected portions of the screen space. Primitive assembly is performed on the vertices to generate a one or more primitives in screen space from the projection of the vertices onto the screen space. A finished frame is then generated by performing pixel processing to assign pixel values to the pixel or pixels that are part of the corresponding primitives. In some implementations, the finished frame can be stored in the memory or displayed on the display device.

Abstract: Systems, methods, and devices are disclosed for rendering computer graphics. In various embodiments, a displacement map is created for a plurality of surfaces and a tessellation process is initiated. It is determined that the tessellation density of a first set of surfaces and a second set of surfaces should be modified based on the displacement map. Based on the displacement map, a tessellation factor scale for each surface of the first set of surfaces is increased and a tessellation factor scale for each surface of the second set of surfaces is decreased, respectively.
