START exits the test.
The Control Stick moves the light.
The C Stick rotates the model.
The A Button changes the model.
The B Button toggles the diffusion function (clamped/unclamped).
The X/Y Buttons select an item to be controlled in the following order: Ambient, Light, Material.
The L/R triggers change the brightness value of the selected item. This value is used as the R/G/B value of the selected item.
Looks at a sphere from an angle opposite that of the light with the unclamped diffuse function.
Looks at a torus from an angle perpendicular to that of the light with the unclamped diffuse function.
