c++ vtk创建100*100棋盘格

使用VTK库可以很方便地创建3D图形，以下是创建100*100棋盘格的示例代码：

#include <vtkSmartPointer.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkProperty.h>
#include <vtkPoints.h>
#include <vtkCellArray.h>
#include <vtkPolyData.h>

int main()
{
    // 创建点坐标
    vtkSmartPointer<vtkPoints> points = vtkSmartPointer<vtkPoints>::New();
    for (int i = 0; i < 100; i++)
    {
        for (int j = 0; j < 100; j++)
        {
            points->InsertNextPoint(i, j, 0);
        }
    }

    // 创建单元格
    vtkSmartPointer<vtkCellArray> cells = vtkSmartPointer<vtkCellArray>::New();
    for (int i = 0; i < 99; i++)
    {
        for (int j = 0; j < 99; j++)
        {
            vtkIdType pts[4] = {i * 100 + j, (i + 1) * 100 + j, (i + 1) * 100 + j + 1, i * 100 + j + 1};
            cells->InsertNextCell(4, pts);
        }
    }

    // 创建多边形数据
    vtkSmartPointer<vtkPolyData> polyData = vtkSmartPointer<vtkPolyData>::New();
    polyData->SetPoints(points);
    polyData->SetPolys(cells);

    // 创建映射器和演员
    vtkSmartPointer<vtkPolyDataMapper> mapper = vtkSmartPointer<vtkPolyDataMapper>::New();
    mapper->SetInputData(polyData);

    vtkSmartPointer<vtkActor> actor = vtkSmartPointer<vtkActor>::New();
    actor->SetMapper(mapper);
    actor->GetProperty()->SetColor(0.8, 0.8, 0.8);

    // 渲染器和窗口
    vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
    renderer->AddActor(actor);

    vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
    renderWindow->AddRenderer(renderer);

    // 窗口交互器
    vtkSmartPointer<vtkRenderWindowInteractor> interactor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
    interactor->SetRenderWindow(renderWindow);

    // 渲染并开始交互
    renderWindow->Render();
    interactor->Start();

    return 0;
}

这段代码会创建一个100*100的棋盘格，并在窗口中显示。你可以根据自己的需求修改代码，并添加适当的交互功能。
