Diagnosing raytracing

There are a couple of techniques you can use to cut down on your render times when working with a scene that requires ray tracing to create reflective and refractive surfaces. So, I would like to show you how to use some of these techniques. In this scene, I have a glass vase on a table, and I am going to do a quick render here so we can see what it looks like. It takes about nine seconds to render on this machine, and it's a fairly complex surface, and it's somewhat refractive. Basically mental ray is spending a fair amount of time calculating these refractions.

If you go into the Render Settings under the Quality tab, you'll find that down here at the bottom of the Raytracing section, there is an Acceleration option. These options are there to make rendering reflections and refractions a bit more efficient. The default method for calculating ray tracing is the BSP2. BSP stands for the Binary Space Partitioning. Simply put, when you are rendering a scene with ray tracing, men...
