Fast Precomputed Ambient Occlusion for Proximity Shadows
نویسندگان
چکیده
Ambient occlusion is widely used for improving the realism of real-time lighting simulations. We present a new method for precomputed ambient occlusion, where we store and retrieve unprocessed ambient occlusion values in a 3D grid. Our method is very easy to implement, has a reasonable memory cost, and the rendering time is independent from the complexity of both the occluder and the receiving scene. This makes the algorithm highly suitable for games and other real-time applications.

Real-time ambient occlusion and halos with Summed Area Tables
Volume models often show high depth complexity. This poses difficulties to the observer in judging the spatial relationships accurately. Illustrators usually use certain techniques such as improving the shading through shadows, halos, or edge darkening in order to enhance depth perception of certain structures. Both effects are difficult to generate in real-time for volumetric models. Either th...
متن کاملFast Occlusion Sweeping
While realistic illumination significantly improves the visual quality and perception of rendered images, it is often very expensive to compute. In this paper, we propose a new algorithm for embedding a global ambient occlusion computation within the fast sweeping algorithm while determining isosurfaces. With this method we can approximate ambient occlusion for rendering volumetric data with mi...

Volumetric data sets are often examined by displaying isosurfaces, surfaces where the data or function takes on a given value. We propose a new method for rendering isosurfaces at interactive rates while supporting dynamic ambient occlusion and/or soft shadows and requiring minimal pre-computation time. By approximating the occlusion in a region as the percentage of occluding voxels in that reg...

In this paper, we propose a real-time method for rendering soft shadows and inter-reflections of dynamic objects under complex illumination. In previous methods, many efforts were taken to acquire occlusion and reflection informations for dynamic scene on the fly, and the result image cannot be generated in real time. In our approach, these informations for each object are pre-computed and stor...
