GalaxExplorer is a real-time 3D visualization tool aimed originally at visualizing spectroscopic redshift galaxy catalog. It is more a hobby project than an attempt to do a full featured visualization tool (like Paraview).
- handle large number of particles (tested up to ~64 millions particles on a 4 GB memory laptop);
- support for a number of point representation (points, spheres, tree hierarchical, textured), surface representation, and unstructured mesh representation with triangles (using Delaunay tesselation);
- lagrangian transport of surfaces, with the surface representation mode.
- multiple skyboxes for orientation dependent background;
- real transparency through front peeling algorithm and GLSL shaders;
- support for tracing the trajectory of particles (currently require a large memory to load all particles and all timesteps, but online loading is planned);
- automatic movie capturing;
- remotely controllable through a D-Bus interface (a Python binding is included in the source package, data can be directly uploaded from python);
- snapshoting of the current state and reloading.
- QT4 toolkit
- HealPix, for skybox support
- OpenGL ≥ v2.1, some functionalities may require a higher version.
It is still in heavy development. If you are interested in testing it please contact me at lavaux_at_illinois_edu.
