You must be in the project directory (that is, one directory above the SDL file) when using the stand-alone renderers.
renderer sdl/filename
raytracer sdl/filename
powercaster sdl/filename
To powertrace the scene, type:
powertracer sdl/filename
There are several options that you can use with the stand-alone renderers (see Use a command line rendering program).
The renderer displays information on the elapsed time for each frame and for the total render.
