Info

Rendering the file • To render the file use the following command line render -t:2 simple.rib • This will render the rib file to the framebuffer (i.e. the screen) • • -t:2 tells renderman to use both cpu's for rendering (if you have more increase the value -t:8 ! • To render to file change the Display line to the following Display "HelloWorld.exr" "file" "rgba" • Which will create a file called HelloWorld.exr • We can then use the sho program to view it (sho HelloWorld.exr) Saturday, 23 October 2010
Python Version • The python script to generate the rib file is a lot larger as we need to do some initial setup for the interface • All rib commands belong to the namespace ri and are prefixed with ri • Apart from that the function names are the same as the raw rib commands • The following file was used to create the HelloWorld rib file Saturday, 23 October 2010
