# FlyingFrogSkinAndTissueC

VTKEx/Cxx/Visualization/FlyingFrogSkinAndTissueC

### Description

Frog no skin or skeleton.

This example is a modification of ViewFrogSkinAndTissue using vtkFlyingEdges3D for contouring. However there is an option to use vtkMarchingCubes instead.

Info

See Figure 12-9c in Chapter 12 of the VTK Textbook.

### Download and Build FlyingFrogSkinAndTissueC

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

    cd FlyingFrogSkinAndTissueC/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:

    ./FlyingFrogSkinAndTissueC
