Axes
vtk-examples/CSharp/GeometricObjects/Axes
Description¶
This example shows how to position an AxesActor in 3D. Notice that position and orientation of the AxesActor is done with a user transform.

// because vtkAxesActor uses an overlayed renderer for the axes label
// in total we have now two renderer
