VTK Export for SketchUp is a Visualization Toolkit VTK file export plug-in for Google SketchUp®. This plug-in gives SketchUp the ability to export objects from SketchUp to ASCII and Binary VTK files. VTK Export for SketchUp tessellates objects in a SketchUp document into a set of triangular meshes. These meshes are then exported to a VTK file as mesh objects. The VTK file can then be imported into a variety of CAD applications. VTK Export for SketchUp is very easy to use. Once installed, it automatically loads itself into SketchUp and adds a new submenu called "VTK Export for SketchUp" to the SketchUp Plugins menu containing these newly added commands. The 'VTK Export for SketchUp' menu consists of the following commands: Export - Exports a VTK file Help - Displays the VTK Export for SketchUp help file Register - Registers your copy of VTK Export for SketchUp About - Displays the VTK Export for SketchUp About box The VTK File Format The Visualization ToolKit (VTK) is an open source, freely available software system for 3D computer graphics, image processing, and visualization used by thousands of researchers and developers around the world. VTK consists of a C++ class library, and several interpreted interface layers including Tcl/Tk, Java, and Python. The Toolkit stores geometric data in a file format known as VTK. Very few CAD applications have the ability to read and write VTK files.
