“…By traversing the macrocell hierarchy, we need not consider much of the data that is contained within the shared memory space. For non-volumetric data, we use efficient bounding volume hierarchy and hierarchical grid-based data structures [15,16] for a similar purpose.…”

“…Whitted and Rubin [7] introduced the hierarchical representation for threedimensional objects which have improved both time and space efficiency. These representations typically consist of the trees whose branches represent bounding volumes and whose terminal nodes represent primitive object elements.…”

'Mich a el A. Driscoll l.Cn Ray tracing is a very popular rendering algorithm in the field of computer graphics because it can generate highly-realistic images from three-dimensional models.Unfortunately, the computational cost is very expensive. To speed up the rendering process we present both static and dynamic scheduling (balancing) strategies for a multiprocessor system. Hence, the load balancing among the processors is the most important problem in parallel processing. The implementation of the algorithm is based on a modified octree structure.

“…Surface information is usually encoded in the object structure, that may include textures or complex shading model parameters. One important aspect of geometrical representation is the storage of bounding volume information, and an optional hierarchical ''level of detail''structure (for example that in (Rubin and Whitted 1980)). Finally,the geometry of the scene can be enhanced by structuring information such as relative visibility or object proximity relationships, that are crucial, especially in light transfer calculations.…”

The structure of the sampling and reconstruction process, as well as that of the scene and its data representation, can be utilised to effect significant benefits in global illumination algorithms. As an introduction, previous methods that have utilised this structure are reviewed and some possible improvements are suggested. An ew framework is then introduced that utilises the concept of an oracle as an abstraction to provide information about the complex computational processes of global illumination. This framework is based on the recognition of the relevant aspects of scene structure, the description of the problems to be solved in terms of oracles, the use of structure to create approximations to the oracles, and finally techniques to monitor the cost, error and quality of the approximations. Each aspect of the framework is discussed in detail, presenting certain oracles that are useful for global illumination algorithms. Two examples of its application are presented. The first example is a simple local illumination problem, that allows us to consider several aspects of the oracle methodology. The second example uses the framework to enhance the progressive refinement radiosity based solution to global illumination. Both examples illustrate the benefits of the proposed framework. Finally,some suggestions are made for future research directions.
