“…The CAVE5D [18] work is a CAVE implementation of the Vis5d [19] visualization system, while the CAVE6D [27] is a tool for collaboratively visualizing environmental data. The 3DIVE [4] system combines the concepts of region-based manipulation and data filtering in an immersive environment very useful for medical data. The VR2 [15] system integrates volume rendering with virtual reality using a fast and flexible Java volume visualization toolkit, called RTVR [31].…”

The study of the fluid flow process through porous media can bring valuable contributions in areas like oil exploration and environmental research. In this work, we propose an interactive tool, named VRFluid, that allows visual interpretation of the three-dimensional data generated by the simulation of the fluid flow the porous media. VRFluid comprises a virtual reality engine that provides stereo visualization of the three-dimensional data, and a simulation engine based on a dynamic percolation method to model the fluid flow. VRFluid is composed of two independent main threads, the percolation simulator and the rendering server, that can operate in parallel as a pipeline. We tested our tool on a region of a mature field database, supervised by geophysicists, and obtained images of the interior of the percolation data, providing important results for the interpretation and cluster formation process.

“…A hierarchical approach is used to be able to detect collisions faster, discarding regions of objects that are not colliding. Boyles and Fang (2003) proposed a technique centered on volume rendering using 3D textures (Wilson, Van Gelder, & Wilhelms, 1994), where a proxy mesh is used to display the volume. This method is novel because it does not follow the classic collision detection scheme based on hierarchical bounding volumes, and explodes the frame buffer of the GPU.…”

Collision detection has been studied for scenes containing only polygonal objects (surfaces) or only volumes. With the evolution of the graphics hardware, surfaces and volumes can be rendered together, demanding new challenges for the area of collision detection. In this order of ideas, the authors propose the first approach for volume-surface collision detection, with GPU support. A mapping from surface space to texture space is established, such as each mesh fragment has a 3D texture coordinate. The volume-surface collision is tested in the fragment shader, verifying if a surface fragment is texturized with an opaque voxel. OpenGL® occlusion query extension is used to count the number of mesh fragments colliding with the volume. Since one surface can be texturized with multiple volume textures, the authors' approach is naturally extended to discard collision between one surface and several volumes in a single pass, with a minimum impact in the rendering time. The authors' tests reveal that collision between thousands of volume-mesh pairs can be evaluated in one second, showing that our solution is ideal for real-time applications.
