2DArray
VTKExamples/Cxx/Utilities/2DArray
Description¶
This example creates a 5x5 2D array and sets the (4,4) (zero based indexing, of course) entry to 5.0. Then it outputs this value to demonstrate accessing.
Code¶
2DArray.cxx
#include <vtkSmartPointer.h> #include <vtkDenseArray.h> int main(int, char *[]) { vtkSmartPointer<vtkDenseArray<double> > array = vtkSmartPointer<vtkDenseArray<double> >::New(); array->Resize(5,5); array->SetValue(4,4, 5.0); std::cout << array->GetValue(4,4) << std::endl; return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(2DArray) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(2DArray MACOSX_BUNDLE 2DArray.cxx) target_link_libraries(2DArray ${VTK_LIBRARIES})
Download and Build 2DArray¶
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 Some tarballs may be missing or out-of-date.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 2DArray and its CMakeLists.txt file. Once the tarball 2DArray.tar has been downloaded and extracted,
cd 2DArray/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:
./2DArray
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.
