FrenetSerretFrame
VTKExamples/Cxx/Remote/FrenetSerretFrame
Description¶
Warning
This example requires the remote module ''SplineDrivenImageSampler.''
Next
-
reconfigure with cmake.
-
Then enable the module setting ''Module_SplineDrivenImageSlicer:BOOL=ON'' or ''VTK_MODULE_ENABLE_VTK_SplineDrivenImageSlicer:STRING=WANT''
-
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.

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
WINDOWS USERS
Be sure to add the VTK bin directory to your path. This will resolve the VTK dll's at run time.
