cutealien 3c4ac201ce Add options for transparency node sorting algorithm ... Until last summer we sorted by object origin to camera distance Since then we used nearest transformed bbox-extent to camera. I've now added an enum to allow switching those plus 2 new: - none (so sorting based on scenegraph instead) - object center to camera. Which I made the new default as it worked the best in my tests. I already experimented with a few more ones like different sphere sizes (bbox radius, minimal inbound radius, maximal inbound radius) around center or origin to handle objects with different sizes, but that just gave worse results for all my test cases. Likely algorithms we should still try: - Collision point with bounding-box in line between camera and object center (sounds a bit slow, but maybe worth it) - Distance to camera plane (instead of camera position). But needs additional parameter to distance functions first (maybe normalized view vector will do). That should be useful when working with planar objects. git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6572 dfc29bdd-3216-0410-991c-e03cc46cb475		2023-11-22 14:52:19 +00:00
