Taking 5 to 10 sceonds to show 3D objects

[peter]

when showing 3D objects for first time it takes 5~10 seconds to render. the log shows:

...

is it possible to do those before we call renderer?

thanks!

Yes, you can use compileAllObjects() in World. However, that still won't affect the upload of the compiled data to the gpu.
If your object needs 5-10 secs. to compile, I suggest to check if it really has to be that large. Sounds a bit much for a mobile app at first glance...

I try to move those thing into background, so I can have something to show while 3D renderer is preparing VBO's. does it possible to do those in an Async class instead of in main thread?

[EgonOlsen]

Yes, the compile call can be done in any thread.
