Plane
vtk-examples/Cxx/GeometricObjects/Plane
Description¶
vtkPlaneSource object creates an m x n array of quadrilaterals arranged as a regular tiling in a plane.
The plane is defined by specifying an origin point, and then two other points that, together with the origin, define two axes for the plane. These axes do not have to be orthogonal - so you can create a parallelogram. (The axes must not be parallel.) The resolution of the plane (i.e., number of subdivisions) is controlled by the ivars XResolution and YResolution.
By default, the plane is centered at the origin and perpendicular to the z-axis, with width and height of length 1 and resolutions set to 1.

Download and Build Plane¶
Click here to download Plane and its CMakeLists.txt file. Once the tarball Plane.tar has been downloaded and extracted,
cd Plane/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:
./Plane
WINDOWS USERS
Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
