WebJul 18, 2007 · WPF 3D is not a ray tracer. The two common ways of rendering 3D objects are: Describe objects as polygons (broken into triangles). Do a projection to 2D and use some clever shortcuts to simulate lighting. This is the method used by accelerated graphics APIs, including WPF, Direct3D, OpenGL and their ilk. All real-time games use this method … WebVolume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique.It computes 2D images from 3D volumetric data sets (3D scalar fields).Volume ray casting, which processes volume data, must not be mistaken with ray casting in the sense used in ray tracing, which …

WebRay Tracing. Same idea as ray casting except once you hit a triangle you reflect on it and go into a different direction. The number of reflection you allow is the "depth" of your ray tracing. A depth of 1 is ray casting, a depth of > 6 is usually considered as good approximation of global illumination (which would be infinite depth).
