Unity PhysicsCore2D API — Math Utilities
This skill is the auto-generated API surface for the listed types. It pre-dates Claude's training data on Unity 6000.5, so it should be treated as the source of truth for member names, signatures, and documentation strings.

PhysicsMath
A set of mathematical operations that are useful for physics. These operations do not form a fully comprehensive mathematics library, they simply provide operations that are usually required when interacting with physics.
Calculate a given a 2D angular velocity and a time to integrate over using the selected transform plane. If is used, will be used instead which may not provide the correct results.

Transform a 3D position and rotation to a 2D . Scale is not part of a therefore it is ignored. If is used, will be used instead which may not provide the correct results.
Transform a 3D position into a 2D position using the selected transform plane. This can also be used for a 3D scale vector as it undergoes the same transformation.

Transform a 2D position into a 3D position using the selected transform plane. If is used, will be used instead which may not provide the correct results.
Transform a 2D angle into a 3D rotation using the selected transform plane (Fast). The transformation is fast because the rotation is simplified by the fact that only a single axis of rotation is handled. All other axis rotations are reset to zero. If is used, will be used instead which may not provide the correct results.
Transform a 2D angle into a 3D rotation using the selected transform plane (Slow). The transformation is slower because the rotation is more complex due to the fact that changing a single axis of rotation requires it to not affect any other axis rotations. If is used, will be used instead which may not provide the correct results.
Params:
angle — The 2D angle to transform in radians.
reference — The 3D rotation used as a reference.
transformPlane — The transform plane to use.
