Each shadow-casting light ray needs to test intersection with the objects in only one of the leaf nodes of the quadtree. This helps speed up the ray-tracing process. In general, increasing the maximum quadtree depth can speed up ray-tracing at a cost of memory. The maximum size of a quadtree is the square of two to the power of the maximum quadtree depth. At a depth of 7, the largest quadtree has 128 x 128 leaf nodes; at a depth of 10, the largest quadtree has a size of 1028 x 1028 leaf nodes, and so on. (On the other hand, because each successive node contains fewer objects, the size of a node's record decreases the deeper it is in the tree.) NOTE An omni light can generate up to ten quadtrees, so omni lights that cast ray-traced shadows use more memory at render time than spotlights do. Queue Monitor The Queue Monitor is a standalone network-administration tool that provides a user interface to monitor and control network rendering. The Queue Monitor can connect to any computer to which you have network access with the appropriate security permissions, and a Network Manager running on it. You can install the Queue Monitor separately. It will function correctly on any Intel-based computer running Windows NT with appropriate TCP/IP networking services, including over the Internet. In other words, you can monitor and control network rendering services from any computer connected to the Internet, in addition to using the Internet as a wide-area backbone for a network rendering farm. Radiosity A technique to calculate indirect light to illuminate a scene. Radiosity calculates the interreflections of diffuse light among all the surfaces in your scene. The result is the radiosity solution on page 8101. See Modeling Global Illumination with Radiosity on page 6168. Radiosity Solution The calculation of the radiosity on page 8101 effect in a scene. You compute the radiosity solution as a separate step from rendering. Once the solution is Glossary | 8101
