摘要
This paper introduces the techniques of direct volume rendering in VTK and discusses ray-casting—the most popular technique of direct volume rendering. The visualizations for medical volumetric data by three functions of ray-casting are offered. Visualization effects prove that VTK is easy to get satisfied results with good quality in short time.
