Traditionally in computer graphics complex 3D scenes are represented as a collection of more primitive geometric surfaces. The geometric representation is then rendered into a 2D raster image suitable for display devices.Image based rendering is an interesting addition to a geometry based rendering. Performance is constrained only by display resolution, and not by scene geometry complexity or shader complexity. When used together with a geometry based renderer, an image based renderer can extrapolate additional frames into an animation sequence based on geometrically rendered frames.Existing research into image based rendering methods is investigated in context of interactive computer graphics. Also an image based renderer is implemented to run on a modern GPU shader architecture. Finally, it’s used in a first person shooter game experiment to measure task performance when using frame rate upconversion.Image based rendering is found to be promising for frame rate upconversion as well as for latency compensation. An implementation of an image based renderer is found feasible on modern GPUs. The experiment results show considerable improvement in test subject hit rates when using frame rate upconversion with latency compensation.
