We can get Euler angles about rotation from vtkTransform::GetOrientation.The three float numbers can be regarded as a representation of vector(1, 1, 1). But you can ignore its length to calculate the orientation expression in the target coordinate system.The following image shows Read more…
The interface vtkTransform::GetOrientation returns Euler angles to describes the orientation of a rigid body.The order of rotation axes in this process is Z, X, Y, but the solving sequence in the interface code is reversed.The implementation details about the interface are here. (from VTK8.2.0) Read more…
