How get list positions for many bodyIDs ?

[Ronniko]

In simple sample we get position like this:

b3Vec3 position = b3Body_GetPosition(bodyId);

But if world have 5000 boxes, not good do 5000 times b3Body_GetPosition(bodyId);

My question does box3D have function b3Body_GetManyPositions ?
Good for shader(buffer data) drawInstanced thousands objects.

Ideal variant, get pointer to array Box3D positions group bodyes.
Update gpu buffer and drawInstanced.

Use b3World_GetBodyEvents
