FrenetSerretFrame

VTKExamples/Cxx/Remote/FrenetSerretFrame


Description

Warning

This example requires the remote module ''SplineDrivenImageSampler.''

Next

  1. reconfigure with cmake.

  2. Then enable the module setting ''Module_SplineDrivenImageSlicer:BOOL=ON'' or ''VTK_MODULE_ENABLE_VTK_SplineDrivenImageSlicer:STRING=WANT''

  3. make

The classes used in this example are described in A Spline-Driven Image Slicer. In the example, the normal vectors are yellow, the tangent vectors are red and the binormal vectors are green.

Question

If you have a simple question about this example contact us at VTKExamplesProject If your question is more complex and may require extended discussion, please use the VTK Discourse Forum

Download and Build FrenetSerretFrame

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

cd FrenetSerretFrame/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:

./FrenetSerretFrame
