This week I was experimenting with creating different kinds of glass textures and lighting. Above are various spheres lit in a spotlight. There are four types of glass textures (blinn, phong, phong e, anisotropic).
I used directional lighting for the two above with different views.
Area lighting was used for these last two images. Turning on the caustics, global illumination increased the rendering time but it was interesting to learn what kind of looks you can achieve with the type of lighting you choose.
if you want the shadows to appear in your reflections, turn your ray depth limit up to 2 (each integer is one reflection)
