How I can to split 3d vtk data to 2d series?

Thank you so much! The guy extracting mesh files will reply this Friday.

I have another question. Look at Figure 1. Dicom images have an obvious rotation around the LR axis. I guess the Dicom image system is not LPS. Am I right? This dicom’s patient orientation is [-0.71, 0.71,0,0,0,-1]. That might be the reason why the ground truth (yellow part in Figure 1) is not aligned?

I rotate the mesh around the LR axis in Slicer; the rotated mesh model can be aligned with dicom images in Slicer, as shown in Figure 2.

Figure 1:
