本文介绍了一个使用VTK库实现的三维对象渲染示例，包括锥体、立方体、圆柱和平面的创建及渲染，并展示了如何在同一窗口内设置四个不同的视口来展示这些三维对象。

1、使用基本的三维对象，如锥体，立方体，柱体以及平面等

2、在同一窗口中同时显示多个渲染结果（设置视口）

3、添加基本的鼠标交互，使用鼠标可以转动三维对象

程序运行效果如下图：

相关代码如下：

public class ConeTest {
    //加载动态链接库
    static {
        System.loadLibrary("vtkCommonJava");
        System.loadLibrary("vtkFilteringJava");
        System.loadLibrary("vtkIOJava");
        System.loadLibrary("vtkImagingJava");
        System.loadLibrary("vtkGraphicsJava");
        System.loadLibrary("vtkRenderingJava");
    }
    
    public static void main(String[] args) {
        vtkConeSource cone = new vtkConeSource();
        //设置圆锥的高度和半径
        cone.SetHeight(3);
        cone.SetRadius(1);
        //设置分辨率，值越大，越趋近于圆锥体
        cone.SetResolution(10);
        
        vtkCubeSource cube = new vtkCubeSource();
        //设置立方体的长宽高
        cube.SetXLength(1);
        cube.SetYLength(1.5);
        cube.SetZLength(1);
        
        //创建圆柱体
        vtkCylinderSource cylinder = new vtkCylinderSource();
        //创建平面
        vtkPlaneSource plane = new vtkPlaneSource();
        //创建对应的mapper
        vtkPolyDataMapper coneMapper = new vtkPolyDataMapper();
        coneMapper.SetInputConnection(cone.GetOutputPort());
        
        vtkPolyDataMapper cubeMapper = new vtkPolyDataMapper();
        cubeMapper.SetInput(cube.GetOutput());
        
        vtkPolyDataMapper cylinderMapper = new vtkPolyDataMapper();
        cylinderMapper.SetInput(cylinder.GetOutput());
        
        vtkPolyDataMapper planeMapper = new vtkPolyDataMapper();
        planeMapper.SetInput(plane.GetOutput());
        //创建对应的actor，设置mapper
        vtkActor coneActor = new vtkActor();
        coneActor.SetMapper(coneMapper);
        
        vtkActor cubeActor = new vtkActor();
        cubeActor.SetMapper(cubeMapper);
        
        vtkActor cylinderActor = new vtkActor();
        cylinderActor.SetMapper(cylinderMapper);
        
        vtkActor planeActor = new vtkActor();
        planeActor.SetMapper(planeMapper);
        //针对每个actor创建一个vtkRender，添加actor
        vtkRenderer ren1 = new vtkRenderer();
        ren1.AddActor(coneActor);
        //下面的代码就是设置视口的，将屏幕分为4个视口
        //前两个参数是视口左下角点的坐标(xmin,ymin)，后两个参数是右上角的坐标(xmax,ymax)
        ren1.SetViewport(0, 0.5, 0.5, 1);
        ren1.SetBackground(0.1, 0.2, 0.4);
        
        vtkRenderer ren2 = new vtkRenderer();
        ren2.AddActor(cubeActor);
        ren2.SetViewport(0.5, 0.5, 1, 1);
        ren2.SetBackground(0, 1, 0);
        
        vtkRenderer ren3 = new vtkRenderer();
        ren3.AddActor(cylinderActor);
        ren3.SetViewport(0, 0, 0.5, 0.5);
        
        vtkRenderer ren4 = new vtkRenderer();
        ren4.AddActor(planeActor);
        ren4.SetViewport(0.5 , 0, 1, 0.5);
        ren4.SetBackground(0, 0, 1);
        
        vtkRenderWindow renWin = new vtkRenderWindow();
        renWin.AddRenderer(ren1);
        renWin.AddRenderer(ren2);
        renWin.AddRenderer(ren3);
        renWin.AddRenderer(ren4);
        renWin.SetSize(500, 400);
        
        //添加鼠标交互
        vtkRenderWindowInteractor interactor = new vtkRenderWindowInteractor();
        interactor.SetRenderWindow(renWin);
        vtkInteractorStyleTrackballActor style = new vtkInteractorStyleTrackballActor();
        interactor.SetInteractorStyle(style);
        //初始化交互器 并开始执行事件循环
        interactor.Initialize();
        interactor.Start();
    }
}
