I would like to perform the following task. I have a 3D<br>
model which I render and then I determine a ROI on the rendered image<br>
(could be also specified beforehand). After that I would like to<br>
render only the 3D points that fall in that ROI. Is there any simple<br>
way to do this?<br>
Thanks in advance.<br>
Best regards,<br>
