FrenetSerretFrame
VTKExamples/Cxx/Remote/FrenetSerretFrame
Description
This example requires the remote module ''SplineDrivenImageSampler.'' Check to see if the file ''SplineDrivenImageSlicer.remote.cmake'' exists in VTK/Remote. If it does not, copy this file to ''VTK/Remote/SplineDrivenImageSlicer.remote.cmake''.
Next
-
reconfigure with cmake.
-
Then enable the module setting ''Module_SplineDrivenImageSlicer:BOOL=ON''
-
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.
