We introduce a novel and efficient method for rendering large models composed of individually-oriented voxels. The core of this method is a new algorithm for computing the intersection point and normal of a 3D ray with an arbitrarily-oriented 3D box, …
Discrete voxel representations are generating growing interest in a wide range of applications in computational sciences and particularly in computer graphics. In this chapter, we first describe an efficient OpenGL implementation of a simple surface …
Indirect illumination is an important element for realistic image synthesis, but its computation is expensive and highly dependent on the complexity of the scene and of the BRDF of the involved surfaces. While off-line computation and pre-baking can …
