PySplotch
Rationale
Splotch is a software for visualizing simulation originally written by Klaus Dolag and Martin Reinecke. The original website is https://wwwmpa.mpa-garching.mpg.de/~kdolag/Splotch/.
PySplotch is a trimmed down version, alongside a python binding. I removed the CUDA acceleration and allowed for more generic data exchange between the rendering core and the user. Notably there is now a Python binding and a number of helper object to control the camera, the transition between datasets and the generation of a large number of images for video making.
The source code may be found here: https://bitbucket.org/glavaux/pysplotch/.
