Hi VTK users,
I am trying to use vtkMultiBlockDataSet + vtkCompositePolyDataMapper to handle lots of dimension/tolerance labels (which has numbers, symbols and frames), but found that vtkFollower did not work correctly – it looks like that the follower treats all the data blocks as one, thus the labels do not move correctly when rotating the scene with mouse. Could anyone please help share some experience or hints on handling this issue? Should I customize a follower or a composite mapper? Or should I update the raw data based on the posture of the camera? How to do that? Please kindly teach me the guidlines. Thanks a lot!
About labeling the geometry parts’ dimension and tolerance, is there any suggestion? Thanks!
By the way, choosing vtkMultiBlockDataSet is aimed to handle thousands of labels with good interaction experience. Have tried using vtkVectorText + vtkPolyData + vtkFollower for each label.
Best regards,
Yongjin
