A Cost Metric for Scene-Interior Ray Origins

We then discussed some supply and demand variables. There exist both supplier and buyer power in the defence market. A change in the relative strength between suppliers and buyers

As with other devices, the host uses the information retrieved from the device to find a matching driver for each active interface in the configuration. The device is now ready

The 3 following states, precomputaiion, distribution and RC, handle the voxel part of the image synthesis process, which has to discretize the objects of the scene into

ABSTRACT Multiprocessor systems are well suited to ray tracing, since each ray can be traced independently. However, the large databases required to model

al / A Spatial Representation for Ray-Scene Intersection Test Improvement in Complex Scenes a photon tracing system.. The resulting rays are used

In this context, grid data structures [Gla84] becomes an appealing data structure: although kd-trees outperforms grids with respect traversal time, they are not suitable for dy-

Let T cost (A) denote the computational cost to test if a given ray hits node A, ie: number of instructions needed to test ray hits against A bounding volume.. Using the

We have tested our iterative ray-tracing collision detection algorithm with two different scenes.. The first experimental scene is an avalanche of 512 concave meshes on a planar
