Example1
- CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(TestVTKInstall)
set(VTK_DIR D:/VTK/VTK-8.2.0-build)
find_package(VTK REQUIRED)
message(${VTK_LIBRARIES})
include(${VTK_USE_FILE})
add_executable(${PROJECT_NAME} TestVTKInstall.cpp)
target_link_libraries(${PROJECT_NAME} ${VTK_LIBRARIES})
- TestVTKInstall.cpp
#include "vtkRenderWindow.h"
#include "vtkSmartPointer.h"
int main(){
// 智能指针定义一个窗口
vtkSmartPointer<vtkRenderWindow> renWin = vtkSmartPointer<vtkRenderWindow>::New();
renWin->Render(); // 显示并渲染窗口

//// 方式一 设置property属性
//cylinderActor->GetProperty()->SetColor(1.0, 0.0, 0.0); // 设置property属性
//// 方式二 设置property属性
//vtkSmartPointer<vtkProperty> cylinderProperty = vtkSmartPointer<vtkProperty>::New();
//cylinderProperty->SetColor(1.0, 0.0, 0.0);
//cylinderActor->SetProperty(cylinderProperty);
// 负责管理场景的渲染过程,组成场景中所有对象 包括Prop, Camera, Light等

// 将操作系统与VTK渲染连接到一起

renWin->AddRenderer(renderer);
renWin->SetSize(300, 300); // 窗口大小 像素为单位
// 提供平台独立的响应鼠标 键盘 和 时钟事件的交互机制
vtkSmartPointer<vtkRenderWindowInteractor> iren = vtkSmartPointer<vtkRenderWindowInteractor>::New();
iren->SetRenderWindow(renWin); // 设置渲染窗口
// 交互器样式的一种
