In this test we will compare Geo Light sampling technology in 3Delight OSL, Arnold and RenderMan. We will use a test with a geometric area light that is composed of a relatively large number of faces. The test should allow us to find out how the algorithm in general noise level and local adaptivity. We will use 2 different cameras to test these two aspects.
The Scene
The test scene allows for procedural generation of floating area lights using the "Tubes Per Step" PaintEffects attribute.
The scene is designed to procedurally generate a number of area lights floating on top of a "city".
