We’re trying out PBRT (Physically Based Rendering) on our cluster for some of the students. Rocks OS doesn’t include it as part of the installation package (it has to be installed from source) and it depends on openexr, a package that was developed at ILM to provide high dynamic-range (HDR) image file format.
Openexr does have a rpm package available, but not in the repository Rocks OS uses. I downloaded it from DAG along with openexr-devel, uses the version which corresponds to CentOS 4 (RedHAT EL 4) since I belive that is the source for the Rocks OS version I am using. The only gotcha during the compile was having to change the include directories for Openexr in pbrt’s Makefile from /usr/local/include to /usr/include and the lib directory to lib64, since we’re running 64 bit.
If pbrt works okay on the test node, I’ll install it on the rest of the cluster.
