Visualization of Astronomical Data Cubes

This is a fun side project with Star Formation Group of Physics Dept., CUHK.
Having tons of Astronomical Data Cubes (either from observation or computer simulation), researchers are interested in finding out secrets in the cube to inspire or to verify their theories. I stayed almost a week in CUHK and quickly developed a visualization tool to meet their needs. I am quite good at 3D rendering (and C++), so my first attempt was to make a ray-marching rendering technique to visualize these cubes. Each cube is so hug (4+ GBs), it's impossible to animate in real-time, so the only chance is to load cube by cube according to their timestamp, given a flying path for the virtual camera (or view point) and output rendered images frame by frame. then, stack all frames we have a movies. Here, it shows the animation of gas density data.
There is also VR mode for single cube visualization in Vive Pro VR system, makes the researcher feel the cube (from any view angles) like they never did before. It's awesome.
