InverseTransformVectors(ReadOnlySpan<Vector3>, Span<Vector3>)

Transforms the vector 
x
, 
y
, 
z
from world space to local space writing the transformed positions to a possibly different location. The opposite of Transform.TransformVector.
public void InverseTransformVectors(ReadOnlySpan<Vector3> vectors, Span<Vector3> transformedVectors)

Parameters

vectors

ReadOnlySpan<Vector3>
The vectors to be transformed, these vectors are not modified by the function unless the 
transformedVectors
span overlaps.

transformedVectors

Span<Vector3>
Receives the transformed vectors, must be the same length as 
vectors
otherwise an exception will be thrown. If this span overlaps 
vectors
other than representing the exact same elements the behaviour is undefined.

Remarks

This operation is not affected by position of the transform but it is affected by scale.The transformed vectors may have different lengths than the originals.

InverseTransformVectors(Span<Vector3>)

Transforms multiple vectors from world space to local space overwriting each original position with the transformed version. The opposite of Transform.TransformVectors.
public void InverseTransformVectors(Span<Vector3> vectors)

Parameters

vectors

Span<Vector3>
The vectors to be transformed, each is replaced by the transformed version.

Remarks

This operation is not affected by position of the transform but it is affected by scale. The transformed vectors may have different lengths than the originals.
