Description

See Parametric Equations for Surfaces by Andrew Maclean for an excellent description of these beautiful parametric surfaces.

You can edit the following code by selecting any one of the functions and the corresponding object will be displayed.

ParametricObjects.cxx

#include <vtkPolyDataMapper.h>
#include <vtkActor.h>

#include <vtkRenderWindowInteractor.h>
#include <vtkParametricFunctionSource.h>

Download and Build ParametricObjects

Click here to download ParametricObjects. and its CMakeLists.txt file.

Once the tarball ParametricObjects.tar has been downloaded and extracted,

cd ParametricObjects/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:

./ParametricObjects

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.
