Hi, thanks Andy, for the information about python and povray. Pvpython and pvbatch sound good. Maybe the matlab interface also provides what I need. Indeed, I need to automate the process to read in text files with coordinates and set then objects at these coordinates. I am now half-way through parsing the text file and setting the objects in C++ and I don't want to change again to a different language. Could somebody provide an example of how to write a povray file with the current camera view in C++? thanks, Benjamin.
