Package

Supports dynamics

PointLight[col_RGBColor, position_:{0,0,10}, intensity_:100, distance_:0, decay_:2]

represents an artificial point-light source at the given position and parameters.

Graphics3D[{Black,Polygon[ {{-5,5,-1}, {5,5,-1}, {5,-5,-1}, {-5,-5,-1}}], White, Cuboid[{-1,-1,-1}, {1,1,1}], PointLight[Red, {1.5075, 4.1557, 2.6129}, 100], PointLight[Cyan, {-2.4489, -1.9012, 2.8386}, 100]}, "Lighting"->None]
