Open Source GLSL (OpenGL Shading Language) Simulation Software

gVirtualXRay is a C++ library to simulate X-ray imaging. It is based on the Beer-Lambert law to compute the absorption of light (i.e. photons) by 3D objects (here polygon meshes). It is implemented on the graphics processing unit (GPU) using the OpenGL Shading Language (GLSL). SimpleGVXR is a smaller library build on the top of gVirtualXRay. It provides wrappers to Python, R, Ruby, Tcl, C#, Java, and GNU Octave.

ParticleVis is a visualization tool specialized for loading and exploring particulate simulation data. It contains a set of features that enables powerful and useful visualizations of particle simulations to be quickly generated. Support is provided for visualization of hundreds of thousands of particles on commodity workstations, using OpenGL. Functionality includes data exploration, debugging of simulation output, and generation of presentation-quality imagery. The ability to visualize vector flow information in a variety of forms, such as arrow-lines, inscribed glyphs, and motion blurred particles, is particularly useful in the study of granular flows. User-generated information can be integrated into the visualization using features such as per-particle color maps and surface maps, per-region vector fields, and volumetric data.

The project is built as a game in Unity. It is an SPH simulator. Allows you to play with real-time fluid simulation.
