Visibility-guided rendering to accelerate 3D graphics hardware performance
Dave Kasik · 2007
Visibility-guided Rendering (VGR) is an output-sensitive approach for real-time rendering of very large 3d data sets, using a GPU. The goal of this section is to understand the foundations of VGR and its application to visualization of complex scenes, using hardware-accelerated OpenGL. The key issues covered in this section are hardware-based occlusionculling, memory management and out-of-core visibility determination, the data structures and algorithms as well as low-level operating system issues.
