DecomposeRigidBodyOrientation(float4x4)

Physics internally represents all rigid bodies in world space. If a static body is in a hierarchy, its local-to-world matrix must be decomposed when building the physics world. This method returns a world-space orientation that would be decomposed for such a rigid body.

Declaration

Parameters

Type	Name	Description
Unity.Mathematics.float4x4	localToWorld

Returns

Type	Description
Unity.Mathematics.quaternion	A world-space orientation as used by physics.

DecomposeRigidBodyTransform(float4x4)

Physics internally represents all rigid bodies in world space. If a static body is in a hierarchy, its local-to-world matrix must be decomposed when building the physics world. This method returns a world-space RigidTransform that would be decomposed for such a rigid body.
