CustomDenseArray
VTKExamples/Cxx/Utilities/CustomDenseArray
Description¶
The only thing you have to do to enable your class to work with vtkDenseArray is add a single line:
Code¶
CustomDenseArray.cxx
#include <vtkSmartPointer.h> #include <vtkDenseArray.h> struct Point { double x,y; operator vtkVariant() const { return vtkVariant(); } }; int main(int, char *[]) { Point point; point.x = 1.0; point.y = 2.0; std::cout << point.x << " " << point.y << std::endl; vtkSmartPointer<vtkDenseArray<Point> > array = vtkSmartPointer<vtkDenseArray<Point> >::New(); array->Resize(5,5); array->SetValue(4,4, point); Point retrievedPoint = array->GetValue(4,4); std::cout << retrievedPoint.x << " " << retrievedPoint.y << std::endl; return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(CustomDenseArray) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(CustomDenseArray MACOSX_BUNDLE CustomDenseArray.cxx) target_link_libraries(CustomDenseArray ${VTK_LIBRARIES})
Download and Build CustomDenseArray¶
Danger
The generation of tar files has not been ported to the new VTKExamples. Some tarballs may be missing or out-of-date.
Click here to download CustomDenseArray and its CMakeLists.txt file. Once the tarball CustomDenseArray.tar has been downloaded and extracted,
cd CustomDenseArray/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:
./CustomDenseArray
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.
