i. Commands • There is usually a direct correlation between the rib commands and the prman_for_python commands • The prman_for_python commands belong to the class prman which we usually assign the prefix pi. and are now functions which may require parameters • In some cases the commands will also require extra parameter lists which are pass using a python dictionary • The following code show some of the commands used to initialise the display and the perspective projection Saturday, 23 October 2010
Set the display options (file,display driver,format) Set image 1 ri.Display("Teapot.exr", "framebuffer", "rgba") 2 3 ri.Format(720,576,1) 4 5 ri.Projection(ri.PERSPECTIVE,{"fov":[35]}) Format (W,H, aspect) Set projection using built in identifier ri.PERSPECTIVE and a dictionary for attributes Saturday, 23 October 2010
