This paper focuses on methods of rendering shadows cast by point light sources. The goal is to summarize advantages and
disadvantages of methods based on shadow mapping. We compare the traditional approach that exploits cube maps with the
Dual-Paraboloid mapping. All of the methods are implemented on the latest hardware and they exploit capabilities of current
GPUs. We also implemented optimization techniques which decrease the computational time. We examine the time the methods
spent in particular rendering passes and we evaluate their overall performance. Finally, we conclude the comparison with some
recommendations for typical applications in which the methods of interest can be exploited. We also suggest some direction of
future investigation. |
