Function b3CreateTransformedHullShape

) -> b3ShapeId

Create a convex hull shape and attach it to a body. The hull is cloned then transformed with scale applied first. Use this for non-uniform or mirrored scale or a baked local transform. The baked result is shared through the world hull database. The shape definition and geometry are fully cloned. Contacts are not created until the next time step. @return the shape id for accessing the shape
