Hybrid Scheduling for Parallel Ray Tracing Hybrid Scheduling for Parallel Ray Tracing
Preface Ray tracing is an easy algorithm to explain, but difficult to implement efficiently. And even then performance is a difficult issue, which calls for every sequential and parallel optimisation that one can think of. This report relates a number of design choices which allowed a sequential ray tracer to evolve into a system for parallel ray tracing and is the result of a two-year (TWAIO) ...
متن کاملRay Tracing using 3D Grid Simulations
Bounding Volume Hierarchies (BVHs) and k-d trees have been used to create interactive ray tracing. Ray tracing dynamic scenes using nVidia’s R © OptiX TM has already provided thirty to sixty frames per second or better. In this paper, we implement space partitioning methods, such as grid method and the proximity clouds (PCs), on multiple GPUs. Our motivation is to investigate the use of such me...
متن کاملA Performance Prediction Tool for Parallel Ray Tracing
This paper proposes a general matrix iterative model to represent a range of dynamic load balancing for MIMD parallel ray tracing. Diierent measure parameters are expressed only on theoretical data. A parallel ray tracing application is implemented. Both results obtained from the model and from parallel implementation are used to compare diierent load balancing strategies and validate the model...
متن کاملBtdf Measurements and Ray-tracing Simulations Comparisons for Prismatic Glazing
Evaluation of solar heat gain and daylight distribution through complex window and shading systems requires the determination of the Bi-directional Transmission Distribution Function (BTDF). In this paper, measurements and ray-tracing-based calculations are compared for the specific case of prismatic daylight-redirecting panels. The latter have been chosen as a validation example because they c...
متن کاملHybrid Scheduling for Efficient Ray Tracing of Complex Images
Ray tracing is a powerful technique to generate realistic images of 3D scenes. A drawback is its high demand for processing power. Multiprocessing is one way to meet this demand. However, when the models are very large, special attention must be paid to the way the algorithm is parallelised. Combining demand driven and data parallel techniques provides good opportunities to arrive at an efficie...
