# TessellatedBoxSource

VTKExamples/Cxx/GeometricObjects/TessellatedBoxSource

### Description

Generates a box(cube) using vtkTessellatedBoxSource with 6 sides. The faces of the box can be subdivided into multiple triangles or quads.

### Download and Build TessellatedBoxSource

Click here to download TessellatedBoxSource and its CMakeLists.txt file. Once the tarball TessellatedBoxSource.tar has been downloaded and extracted,

    cd TessellatedBoxSource/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:

    ./TessellatedBoxSource
