VTK笔记——如何创建圆柱体
VTK是⼀个强⼤的可视化开发⼯具，它提供了很多程序源对象可供我们使⽤。下⾯我们介绍如何创建圆柱体。
VTK创建圆柱体有两种⽅式：
- ⽅式⼀：使⽤vtkCylinderSource来创建。
vtkSmartPointer<vtkCylinderSource> cylinderSource =
vtkSmartPointer<vtkCylinderSource>::New();
cylinderSource->SetHeight(10.0);
cylinderSource->SetCenter(0.0, 0.0, 0.0);
cylinderSource->SetRadius(2.0);
cylinderSource->SetResolution(50);
- ⽅式⼆：使⽤vtkLineSource和vtkTubeFilter来创建。
vtkSmartPointer<vtkLineSource> lineSource =
vtkSmartPointer<vtkLineSource>::New();
lineSource->SetPoint1(5.0, 0.0, 0.0);
lineSource->SetPoint2(-5.0, 0.0, 0.0);
vtkSmartPointer<vtkTubeFilter> tubeFilter = vtkSmartPointer<vtkTubeFilter>::New();training是什么意思
tubeFilter->SetInputConnection(lineSource->GetOutputPort());
tubeFilter->SetRadius(2.0);
tubeFilter->SetNumberOfSides(50);
tubeFilter->CappingOn();
两种⽅式的区别只在于能否任意设置长轴的⽅向。
后悔的英文⽅式⼀只能创建沿着世界坐标系Y轴⽅向的圆柱体，不能任意设置圆柱体长轴的⽅向。
⽅式⼆可以创建具有⽅向性的圆柱体，通过设置圆柱体长轴的两个端点SetPoint1和SetPoint2。
