Rendering a scene includes setup of the camera and invoking the final renderer.
Step 1: Switch the type of the view window to
"Perspective" using the shortcut
The view changes as displayed in figure 16:
We start a first test rendering now.
Step 2: Start the BMRT-OpenGL previewer (rgl) using
<Ctrl-r>. The result should look like
(If Ayam now complains about rgl not being found, BMRT is not set
up correctly. Please read and execute the BMRT installation instructions
again, then return here.)
As you can see, the sphere is a bit too small and not centered.
We will fix this now.
You can get rid of the preview window using the
Step 3: Select the sphere in the main window.
Step 4: Go back to the view and press
This shortcuts changes the parameters of a view so that it displays
the center of the selected objects and adapts the zoom factor
of the view so that the selected objects are well sized.
Step 5: Start the BMRT-raytracer (rendrib) using the
<Ctrl-R> (note the capital r; you have to press
Control, Shift, and r simultaneously!).
You have to wait a bit until the renderer finishes the image
as displayed in figure 18:
Your homework for today:
Make the lighting in this image more interesting with a spotlight. Here is what to do (the tutorial should have teached you how to execute the following tasks):
"Side", then move the light using an interactive modeling action so that it lights the sphere (the arrow of the light source should point directly onto the sphere when you are finished). If you do not move the light, it will probably be located inside the box and not be able light anything!
