چکیده

ParaView is a popular open-source general-purpose scientific visualization application. One of the many visualization tools available within ParaView is the volume rendering of unstructured meshes. Volume rendering is a technique that renders a mesh as a translucent solid, thereby allowing the user to see every point in three-dimensional space simultaneously. Because volume rendering is computationally intensive, ParaView now employs a unique parallel rendering algorithm to speed the processes. The parallel rendering algorithm is very flexible. It works equally well for both volumes and surfaces, and can properly render the intersection of a volume and opaque polygonal surfaces. The parallel rendering algorithm can also render images for tiled displays. In this paper, we explore the implementation of parallel unstructured volume rendering in ParaView.

Implementation of Cell-Projection Parallel Volume Rendering with Dynamic Load Balancing

A parallel volume rendering system for unstructured grid volume data is proposed in this paper. By implementing the mechanism for dynamic load balancing into the system, the authors solve the issue of load imbalance due to the view dependency and run-time features of early ray termination. An experimental implementation of the system achieved a 4.32-times performance

Cell-projection Parallel Volume Rendering with Early Ray Termination

A cell-projection parallel volume rendering system for unstructured grid volume data is proposed in this paper. For this system, the modified early ray termination scheme is proposed to prune the cell-projection of invisible cell. In order to alleviate load imbalance due to view-dependency in scan-conversion and the dynamic behavior of early-ray termination, the authors also implement dynamic l...

Adaptive decomposition and remapping algorithms for object-space-parallel direct volume rendering of unstructured grids

Object space (OS) parallelization of an efficient direct volume rendering algorithm for unstructured grids on distributed-memory architectures is investigated. The adaptive OS decomposition problem is modeled as a graph partitioning (GP) problem using an efficient and highly accurate estimation scheme for view-dependent node and edge weighting. In the proposed model, minimizing the cutsize corr...
