A Parallel Volume Rendering Algorithm Based on MPI
Shaoqun Zeng · Jisuanji gongcheng · 2005
An algorithm——Master-Slave model for parallel volume rendering based on MPI is presented. According to the features of the ray-casting method, a task division strategy of image space is chosen for speeding up rendering, and a dynamic load balance is obtained via taskpools scheme. The algorithm introduced in this paper has been implemented, and experiment is done on the head and feet dataset of virtual Chinese female No.1 (VCH-F1), results show that this algorithm is provided with good parallel efficiency.
