Light Energy Design Influence to Caustic Effect of 3D Transparent Objects

This research makes a software which can produce reflective and transparent object. Reflective object will modeled can reflect another object surrounding it. And transparent object will modeled can produce caustic effect, thats rays which refract in one area. So that area will appear brighter than area surround it. The transparent objects in this research are ball, cube, tube, cube. The result that using software Delphi 7 dan OpenGL is showing up caustic effect of transparent object. Using backward ray tracing and photon mapping, this research will compare the caustic effect of 3D transparent objects according to light energy design.
