# First we setup the output file 
Display "crosstile.tif" "file" "rgb"

# Then set the x & y resolution of the image and the pixel aspect
# ratio (1 = square pixels)
Format 320 240 1

# We now setup the camera (projection type and field of view)
Projection "perspective" "fov" 35

# Move the world 16 units away from the camera and position it
# so the view is to the left of the camera and down from the cameras
# point of view.
