VTKExamples/Cxx/SimpleOperations/ProjectPointPlane
Description
This example projects a point onto a plane. To use this example, you must have the CVSHEAD version of VTK (as of 2/2/2010).
Code
ProjectPointPlane.cxx
#include <vtkSmartPointer.h>
#include <vtkPlane.h>
int main(int, char *[])
{
vtkSmartPointer<vtkPlane> plane =
vtkSmartPointer<vtkPlane>::New();
plane->SetOrigin(0.0, 0.0, 0.0);
plane->SetNormal(0.0, 0.0, 1.0);
double p[3] = {23.1, 54.6, 9.2};
double origin[3] = {0.0, 0.0, 0.0};
double normal[3] = {0.0, 0.0, 1.0};
double projected[3];
plane->ProjectPoint(p, origin, normal, projected);
std::cout << "Projected: " << projected[0] << " "
<< projected[1] << " " << projected[2] << std::endl;
return EXIT_SUCCESS;

Download and Build ProjectPointPlane
Click here to download ProjectPointPlane and its CMakeLists.txt file. Once the tarball ProjectPointPlane.tar has been downloaded and extracted,
cd ProjectPointPlane/build
If VTK is installed:
cmake ..
If VTK is not installed but compiled on your system, you will need to specify the path to your VTK build:
cmake -DVTK_DIR:PATH=/home/me/vtk_build ..
Build the project:
make
and run it:
./ProjectPointPlane
WINDOWS USERS PLEASE NOTE: Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
