Software renderers don?t require 3D acceleration hardware and thus perform all calculations on the CPU. There are two types of software renderers: polygonal and raytracing. Polygonal renderers calculate light in the corner of objects and interpolate it over the object. Raytracing renderers perform physical simulation of light distribution and produce photorealistic images.

Raytracing
Raytracing allows creation of photorealistic images and shadows. Box Shot 3D calculates millions of light rays passing from the light source to the object. The result is a very realistic looking object. Raytracing is usually used for special effects in movies. Box Shot 3D allows you to use this technology for creating box shots!

Realistic Shadows
The use of raytracing leads to ?realistic? shadows. Box Shot 3D calculates the amount of light for every pixel in your image. Box Shot 3D also calculates skylight (or atmospheric light) - light emitted by sky. This makes images look even more realistic.
