In this short Appendix to "Tutorial: Rendering Caustics in Brazil r/s" I will make a simple demonstration of how caustics are generated by different basic geometries. I hope that some of you will find it useful and also it will save you some time on your own projects. Scene settings are the same as in my caustics tutorial with the teapot. I also attempted to use different sizes and positions for the objects to show variations.
