superclass for callback/observer methods vtkCommand is an implementation of the observer/command design pattern. In this design pattern, any instance of vtkObject can be "observed" for any events it might invoke. For example, vtkRenderer invokes…

This example uses a vtkBoxWidget2 to manipulate an actor. The widget only contains the interaction logic; the actual box is drawn by the accompanying vtkBoxRepresentation. Contrary to the older vtkBoxWidget, this widget doesn't provide functionality…
1.vtkPlane vtkPlane provides methods for various plane computations. These include projecting points onto a plane, evaluating the plane equation, and returning plane normal. vtkPlane is a concrete implementation of the abstract class vtkImplicitFunct…
1. Level of detail(LoD)多细节层次描述(简称LoD)是实时绘制复杂几何场景的一种有效工具.基于层次结构的动态简化方法能够根据视点的变化,实时连续地转换场景细节模型.在本例中,实现了球体高.低分辨率两个层次的模型渲染. 2. vtkProp 是渲染场景中能够存在的所有对象的抽象超级类(superclass)比如, all actors, volumes and annotations,包括2D和3D.vtkProp的实例可以相应各种render methods(比如,Rend…
