RandomSequence
VTKExamples/Cxx/SimpleOperations/RandomSequence
Description¶
This is the "new" (December, 2009) VTK way to produce random numbers. It is actually a random sequence generator.
Code¶
RandomSequence.cxx
#include <vtkMinimalStandardRandomSequence.h> #include <vtkSmartPointer.h> int main(int, char *[]) { //Create a random sequence generator. vtkSmartPointer<vtkMinimalStandardRandomSequence> sequence = vtkSmartPointer<vtkMinimalStandardRandomSequence>::New(); // initialize the sequence sequence->SetSeed(1); //Get 3 random numbers. double x = sequence->GetValue(); sequence->Next(); double y = sequence->GetValue(); sequence->Next(); double z = sequence->GetValue(); // You can also use seq->GetRangeValue(-1.0,1.0); //to set a range on the random values. //Output the resulting random numbersl std::cout << "x: " << x << " y: " << y << " z: " << z << std::endl; return EXIT_SUCCESS; }
CMakeLists.txt¶
cmake_minimum_required(VERSION 2.8) PROJECT(RandomSequence) find_package(VTK REQUIRED) include(${VTK_USE_FILE}) add_executable(RandomSequence MACOSX_BUNDLE RandomSequence.cxx) target_link_libraries(RandomSequence ${VTK_LIBRARIES})
Download and Build RandomSequence¶
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 Some tarballs may be missing or out-of-date.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 RandomSequence and its CMakeLists.txt file. Once the tarball RandomSequence.tar has been downloaded and extracted,
cd RandomSequence/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:
./RandomSequence
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.
