POV-Ray handles refraction correctly and can simulate distortions such as
glass, diamond, water, plastic, etc.

| (...) This is the difference between a Renderer (like 3DS MAX) and a Raytracer (like POV Ray). POVRay uses real Solid Geometry, where every object is held in memory as a mathematically "pure" object, so a sphere is defined as a true sphere (via the (...) (25 years ago, 28-Feb-99, to lugnet.cad)

| Yes, you have to understand that pov-ray rendered images look so good (and take so much time to be produced) because the physics of light is modeled (hence the reflection refraction and so on and so forth) moreover when you see a textured object (...) (25 years ago, 28-Feb-99, to lugnet.cad)

| I think this depends how POV-Ray handles solid objects. In most 3D rendering programs, what seems to be a solid glass (for instants) is not more than two faces _without_ thickness and nothing between them. If there's nothing between then, then it (...) (25 years ago, 27-Feb-99, to lugnet.cad)
