Finding renderman 1 export PYTHONPATH=$PYTHONPATH:$RMANTREE/bin • Renderman ships with a python interface to the renderman library, we need to tell the python shell where to find this interface • The python shell uses an environment variable called PYTHONPATH to search for python libraries, when using python for renderman we must tell python to search in the $RMANTREE/ bin directory for the python library • This can be done by setting the line above for our shell (usually in .profile or .bashrc) Saturday, 23 October 2010
Basic Renderman commands 1 import prman Load the prman library 2 3 ri = prman.Ri() 4 5 6 filename = "TeapotPY.rib" Create an instance of the prman interface and assign it to the variable ri 7 ri.Begin(filename) 8 9 0 1 2 Scene generation code goes here Begin our scene called “TeapotPY.rib” finally finish our scene 3 ri.End() will cause the rib file to be written Saturday, 23 October 2010
