### Description

This example applies an object at every point. We use a cube for the demo.

### CMakeLists.txt

    cmake_minimum_required(VERSION 2.8)

    PROJECT(Glyph3D)

    find_package(VTK REQUIRED)
    include(${VTK_USE_FILE})

    add_executable(Glyph3D MACOSX_BUNDLE Glyph3D.cxx )

### Download and Build Glyph3D

Click here to download Glyph3D and its CMakeLists.txt file. Once the tarball Glyph3D.tar has been downloaded and extracted,

    cd Glyph3D/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:

    ./Glyph3D

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.
