Methods

Name	Description
Back(in float4x4)	Computes the "back" direction in a transformation matrix's reference frame.
ComputeWorldTransformMatrix(in Entity, out float4x4, ref ComponentLookup<LocalTransform>, ref ComponentLookup<Parent>, ref ComponentLookup<PostTransformMatrix>)	Synchronously compute a local-to-world transformation matrix for an entity, using the current values of LocalTransform and PostTransformMatrix for the target entity and its hierarchy ancestors.
Down(in float4x4)	Computes the "down" direction in a transformation matrix's reference frame.
Forward(in float4x4)	Computes the "forward" direction in a transformation matrix's reference frame.
InverseTransformDirection(in float4x4, in float3)	Transforms a 3D direction by the inverse of a 4x4 transformation matrix.
InverseTransformPoint(in float4x4, in float3)	Transforms a 3D point by the inverse of a 4x4 transformation matrix.
InverseTransformRotation(in float4x4, in quaternion)	Transforms a 3D rotation by the inverse of a 4x4 transformation matrix.
Left(in float4x4)	Computes the "left" direction in a transformation matrix's reference frame.
LookAtRotation(in float3, float3, float3)	Computes a rotation so that "forward" points to the target.
Right(in float4x4)	Computes the "right" direction in a transformation matrix's reference frame.
Rotation(in float4x4)	Extracts the rotation from a transformation matrix
Scale(in float4x4)	Extracts the scale from a transformation matrix
TransformDirection(in float4x4, in float3)	Transforms a 3D direction by a 4x4 transformation matrix.
TransformPoint(in float4x4, in float3)	Transforms a 3D point by a 4x4 transformation matrix.
TransformRotation(in float4x4, in quaternion)	Transforms a 3D rotation by a 4x4 transformation matrix.
Translation(in float4x4)	Extracts the translation from a transformation matrix
Up(in float4x4)	Computes the "up" direction in a transformation matrix's reference frame.
