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(More)
Figure 2. Images rendered with bilinear 4-ray (top) and 6-ray (bottom) cameras. Figure 1. (Left) Approximation of catadioptric system with two partial-sphere mirrors and a perspective camera, creating first (red and green) and second (yellow and blue) order reflected rays. The image is triangulated into simple cameras (ε = 1pix). The right image was(More)
This paper presents sample-based cameras for rendering high quality reflections on convex reflectors at interactive rates. The method supports change of view, moving objects and reflectors, higher order reflections, view-dependent lighting of reflected objects, and reflector surface properties. In order to render reflections with the feed forward graphics(More)
We propose a two phase hybrid reflection rendering method based on approximating the reflected rays with a set of simple cameras modeled as continuous 3-ray cameras. In the first, "backward", phase, the view volume of each simple camera is intersected with a hierarchical subdivision of the scene to find the geometry it encompasses. In the second, "forward",(More)
