jMonkeyEngine
Animated models should have proper model bound
Reference on googlecode: https://code.google.com/p/jmonkeyengine/issues/detail?id=343
This issue has been bugging me for some time. Unfortunately, I don't see any way to address it without recalculating the bound on every frame --- a big hit to performance.
It doesn't need to be recalculated every frame as the issue mentions... it just needs to be a max extent for all frames (calculated once). However, it might be reasonable compromise to just recommend that users set their own bounding box that is 'big enough'.
The max extent of all frames is a good solution for keyframe animations using the default animation channel. But that would leave closely-related issues when custom animation channels are used to blend animations together, or when a user transform is applied to a Bone. My usual workaround in these cases is to disable scene-graph culling.
But you might as well just give it a bounding box of 1,000,000x1,000,000 in that case. Surely there is a compromise on your bounding box.
I think if this issue is on the old animation system, it should be closed.
