[osg-users] How to speed up rendering in this case.

[Jinh Tang]

Hi All,
    suppose 
1,   I have 1000  meshes, and each mesh has 12000 points to draw. (to create 1000 geometry and add them to node in main GUI thread?)

2,   also have another work thread, it will modify above 1000 meshes at any time.  (will setDataVariance to Dynamic and modify geometry in this thread work?)

3,   3rd thread, will add new or delete some old geometry at any time...


I tried 
1, set DataVariance to Dynamic, doesn't work. crash happen.
2, in thread 2 & 3, only create vertices&colors&normals, and use them in thread 1, doesn't work, crash happen.

I am stuck on this problem for 2 weeks.....



... 

Thank you!

Cheers,
Jinh
