Two tools to work and experiment with lightcurves (non production).
##Lightcurve Generator The Lightcurve Generator is a web tool which calculates lightcurves of either user defined binaries or .obj files. It's not fully working and not under development anymore.
The screenshot shows the tool in use with a loaded .obj file.
##Lightcurves Blender A small tool which draws a light curve out of an image set which renders an object over a whole rotation (360 deg). It's not required to work in combination with the free open-source software Blender - but it's probably the easiest way to use it. Opposed to the prior tool this one is fully functional.
