function<br></font><br>
Hi! All<br><br>I can find all intersected surface sets with "MBOrientedBoxTreeTool::ray_intersect_sets" function and large tolerance, but it takes too long time.<br>So, I made "MBOrientedBoxTreeTool::ray_intersect_all_sets" function to find intersected boxes at first and find all surface sets and triangles intersected with small tolerance like "MBOrientedBoxTreeTool::ray_intersect_triangles" function which is much faster.<br><br>To minimize possible errors with other codes, I made it as a new function not modyfing existing "MBOrientedBoxTreeTool::ray_intersect_sets" function.<br><br>Is it ok to all for me to commit it?<br>Thanks.<br><br>Hong-Jun<br></div></div>
