Difference about Triangle Mapping And Orient

I want to know what difference about Transform.Affine.Triangle Mapping And Transfom.Euclidean.Orient? It seems they are same. Why Make two components about one same function?

Thank you!

Hi. Jack.

As far as I know ~

Affine transformation can deform original shape and also can scaling original.

Euclidean transformation can't deform original shape but, can transfer original shape topologically.

Triangle mapping allows for both scaling (different size triangles) and shearing (different shape triangles). Orient transform only supports translation and rotation.

Can I say that Triangle Mapping can replace Orient Transform?

Yes, Triangle Mapping can do everything that Orient can do, and more. However you need to make triangles for it to work, so it's often more difficult to use.
