toTransform Method

Populate a Transform from the instance, even if the transformations aren't equivalent.

• A Transform cannot encode perspective, but this method returns one even if it isn't equivalent to the instance.
• Compare to the asTransform property, which returns undefined when there is perspective.

toTransform(result?: Transform): { isValid: boolean, transform: Transform }

@returns derived Transform and a flag indicating its validity:

• transform is filled with the top three rows of the instance's entries scaled by the reciprocal of nonzero weight; if weight is zero, transform is set to the identity.
• isValid is true if and only if the last row of the instance is essentially [000w] for nonzero w = weight.

@see asTransform

Returns - { isValid: boolean, transform: Transform }

derived Transform and a flag indicating its validity:

• transform is filled with the top three rows of the instance's entries scaled by the reciprocal of nonzero weight; if weight is zero, transform is set to the identity.
• isValid is true if and only if the last row of the instance is essentially [000w] for nonzero w = weight.
