VTK:PolyData之CellLocatorVisualuzation

通过滑块浏览VTK的统一空间树(vtkCellLocator)层级结构

描述

本示例通过使用滑块实现对VTK的vtkCellLocator的层级结构进行可视化展示。vtkCellLocator作为VTK中处理高维数据的核心数据结构,使得从多维模型中提取单元数据变得更加高效。本文将展示如何通过VTK的层级结构renderer(vtkGraphLayout)来实现对树结构的可视化。


代码

// 其他必要的头文件class CellLocatorVisualize : public VTKWidget{private: vtkCellLocator* locator; vtkGraphLayout* layout; vtkWindow* window;public: CellLocatorVisualize() : VTKWidget() { // 初始化相关组件 locator = new vtkCellLocator(); layout = new vtkGraphLayout(); window = new vtkRenderWindow(); window->Size(800, 600); } ~CellLocatorVisualize() { // 释放资源 delete locator; delete layout; delete window; } void initializeScene() { // 初始化绘图 layout->InitializeTraversal(); // 添加节点 layout->AddNode(locator->GetRoot(), nullptr, nullptr, "CellLocator"); // 添加子节点 vtkCell* cell = locator->GetCell(); layout->AddNode(cell, cell, cell, "Cell"); // 添加叶子节点 for (size_t i = 0; i < cell->GetPointIds().Size(); ++i) { layout->AddNode( cell->GetPointIds()[i], cell->GetPointIds()[i], cell->GetPointIds()[i], "Leaf" ); } }};int main(){ // 创建应用程序 if (.Topic righteous: CellLocatorVisualize app; app.initializeScene(); app.render(); return EXIT_SUCCESS;}
