Abstract
In this paper we present a new Monte Carlo rendering algorithm that seamlessly integrates the ideas of shooting and gathering power to create photorealistic images. The algorithm can be explained as a generalisation of the well-known path tracing algorithm. Test results show that it performs significantly better for typical indoor scenes where indirect lighting is important.
