PCL+VS报错：VTK相关报错

PCL1.8.0对应的是VTK7.0。。。VTK主要用于三维显示，所以如果出错，可以都注释掉，不影响其他函数的正常运行。

1、出现vtkRenderingOpenGL_AutoInit_Construct(void)报错：

在使用计算最小包围盒时报错，且无法运行。

（1）具体报错为：

error LNK2019: 无法解析的外部符号"void __cdecl vtkRenderingOpenGL_AutoInit_Construct(void)"(?vtkRenderingOpenGL_AutoInit_Construct@@YAXXZ)，该符号在函数 "public:__cdecl vtkRenderingOpenGL_ModuleInit::vtkRenderingOpenGL_ModuleInit(void)"(??0vtkRenderingOpenGL_ModuleInit@@QEAA@XZ) 中被引用

error LNK2019: 无法解析的外部符号"void __cdecl vtkRenderingOpenGL_AutoInit_Destruct(void)"(?vtkRenderingOpenGL_AutoInit_Destruct@@YAXXZ)，该符号在函数 "public:__cdecl vtkRenderingOpenGL_ModuleInit::~vtkRenderingOpenGL_ModuleInit(void)"(??1vtkRenderingOpenGL_ModuleInit@@QEAA@XZ) 中被引用

（2）原因：自己的VTK中OpenGL是OpenGL2

（3）方法：参考文献：http://tieba.baidu.com/p/4551950404#93116920200l

因此把源程序中的：

#include          

VTK_MODULE_INIT(vtkRenderingOpenGL);

VTK_MODULE_INIT(vtkInteractionStyle);

VTK_MODULE_INIT(vtkRenderingFreeType);

改成：

#include         

//VTK_MODULE_INIT(vtkRenderingOpenGL);  //自己的PCL1.8.0安装后产生的是OpenGL2,所以这一句需要改成OpenGL2.

VTK_MODULE_INIT(vtkRenderingOpenGL2);  //解决方法参考【http://tieba.baidu.com/p/4551950404#93116920200l】

VTK_MODULE_INIT(vtkInteractionStyle); //外部依赖项添加opengl32.lib（我自己的还要添加vfw32.lib你的不知道要不要）

VTK_MODULE_INIT(vtkRenderingFreeType);

然后，在工程属性->链接器->输入->附加依赖项中添加：opengl32.lib和vfw32.lib

 2、出现ERROR: 0:2: '' :  extension 'GL_EXT_gpu_shader4' is notsupported报错（不影响其他计算）

在region growing和最小包围盒时都会报错，可以运行除了显示之外的其他代码。

（1）具体报错：ERROR: In F:\PCLdon\VTK-7.0.0\Rendering\OpenGL2\vtkShaderProgram.cxx,line 370

（2）原因：这是由于VTK只支持英伟达的显卡。

 

（3）方法：参考文献：https://blog.csdn.net/bai_dreamer/article/details/52934470?readlog 

如果出现这种问题，首先确保你有独立显卡（英伟达的）。找开显卡设置面板，将全局设置那一栏下的首先图形处理器设为高性能NVDIA处理器。
