<div> </div>
<div>I'm new to vtk and have the following problem:</div>
<div>I have an obj file which is captured with a camera system. In the software which deals with this topic, I can select a ROI to do further processing. The ROI is saved in a ROI file. I want to visualize the captured obj file and display the ROI on the captured obj. I'm not sure what is saved in the ROI file but I think it represents the index of the faces in the obj file. Does anyone have an idea on how to acces the faces? I'm using vtk's objReader but I don't see a way to get acces to the faces.</div>
<div> </div>
<div>Thanks in advance.</div>
<div>Best regards,</div>
<div>Daniel</div></div></body></html>
