| Abstract: | This paper presents a more efficient and accurate method for inverse displacement mapping, methods which attempt to render effects offered by displacement mapping, motion parallax, self-occlusion, self-shadowing and silhouette, without actually perturbing the surface geometry. We first propose an extension to cone step mapping. The extension, Anisotropic Cone Mapping (ACM), provides a more efficient and accurate way for calculating intersections. Anisotropic cones are used as the bounding volume for the empty space above texels, allowing faster convergence and rendering speed. Experiments show that ACM has better rendering quality and convergence speed than previous methods. In addition, we propose a hierarchical adaptive preprocessing method that is around 10 times faster than conventional methods, allowing our space leaping approach to be used for rendering dynamic displacement maps. The proposed method is suited for many real-time 3D applications because of their low memory cost and good performance in both rendering quality and speed. |
