Resumo:
The main motivation for this work is to verify the feasibility of using relief texture mapping in high-demand real-time applications, such as computer games. This dissertation presents an extension to relief texture mapping that supports the representation of effects that depend of viewpoint and illumination direction, which could not be represented with previous techniques. Moreover, it proposes a way to parallelize relief texture mapping between CPU and GPU, using Hyper-Threading technology. In this new approach, each element that belongs to a relief texture is augmented to include three scalar values representing the normal vector of the reproduced surface. So, the illumination can be calculated per pixel. In the proposed approach, the parallelization of the relief texture mapping represents an acceleration of up to 37% when compared to conventional techniques.
