Now to get down to creating pictures in a raytracer. You should already have loaded POVRay. Start the program and lets raytrace some images. We will start with some simple images and then modify the scene. You should see an image of a cube, and in the main POVRay window, a textual description of the scene.
Lets modify the scene now.
Render the picture again. You should now be able to see the distortion of the cube due to the perspective projection. Add a new light source. The new object will be added to the .pov file. The default is blue.
