default complexpl
|
Test browser to apply default values of a PointLight node to complex geometry (ElevationGrid, Extrusion, and IndexedFaceSet). The test should generate all three complex geometry with the default color. IndexedLineSet and PointSet are not lit geometry, therefore are not part of this test. |
|
default primitivespl
|
Test browser to apply all the default values of a PointLight node to simple geometry (cone, sphere, cylinder, box). A row containing all four simple geometry is drawn in the local coordinate system and a PointLight node is defined at the beggining of the test. All figures should be illuminated with white light. |

test ambeffect ambientcom
|
This test addresses the effect of the PointLight ambientIntensity on the ambient of a complex object (IndexedFaceSet). Two IndexedFaceSets are drawn in the local coordinate system and a PointLight is defined to shine on them along the -Z axis. The IndexedFaceSet to the left contains an ambientIntensity 0.3 and the one to the right contains an initial ambientIntensity of 1. The ambientIntensity of the light is increased on both geometry as the animation progresses. Since both materials ambientIntensity are constants, at the end of the animation the one to the right will be brigther than the one to the left. This is because at the end of the animation the figure to the right will have maximum ambient (both material and light ambientIntensity will be 1) |

test ambeffect ambientsim
|
This test addresses the effect of the PointLight ambientIntensity on the ambient of a simple object (Sphere). Two spheres are drawn in the local coordinate system and a PointLight is defined to shine on them along the -Z axis. The sphere to the left contains an ambientIntensity 0.3 and the sphere to the right contains an initial ambientIntensity of 1 The ambientIntensity of the light is increased on both spheres as the animation progresses. Since both materials ambientIntensity are constants, at the end of the animation the one to the right will be brigther than the one to the left. This is because at the end of the animation the sphere to the right will have maximum ambient (both material and light ambientIntensity will be 1) |

If the implementation under test does NOT ignore the radius, then the last figure of each set (except the ones along the +X axis) should not be illuminated. (the last two figures along the +X axis should not be illuminated) |
