How can i set the color and radius value for every point in vtkMRMLMarkupsFiducialNode, with c++ language. Thanks for your help!
Currently, markups module displays all fiducial points with the same radius and one of 2 colors. If you want to set radius and color for each point then you can use a model node for that. You can generate input for the model node using vtkGlyph3D filter.
