To get started:
Bring up a console window (off the Start Menu, under Programs)
Go to the C: disk, and to your file.
Copy C:\BMRT\examples\shadtest.rib to your file (using Windows,
or the console, either one).
In the console window, type:
rendrib shadtest.rib
This should create the file balls.tiff
Look at balls.tif by dragging and dropping it onto the IrfanView
icon.
To make your own files:
Start with the simple file we distribute and add to it.
Edit the .rib file (just the Notepad editor is fine).
Render and view as before. Note that you can save a .gif or .jpg from
IrfanView.
