public class test_beamWidthsim2 extends Object

Test browser to set the beamWidth field to a range of values on a set of a simple geometry (sphere) Seven rows of spheres are drawn in the local coordinate system and a single SpotLight is defined at the center. The lights beamWidth is increased as the animation progesses. The animation is started by clicking on the text above the geometry. The cutOffAngle is set to 0.4 for for the light and is never changed. This should cause that only the area bounded by the beamWidth (as its value is increased) be illuminated at full intensity. The area between the cutOffAngle and the beamWidth will receive gradually less amount of light. The area of illumination shall never be higher than the one bounded by the cutOffAngle regardless of the beamWidth value. A browser may choose to ignore the bemWidth field.
