3D Homography transform

1 June 2012

A 2D homography is the well known ‘perspective transformation’, File::DXF contains a tool for performing a plane-preserving, collinear homography on 3D objects. This is distinct from the ‘taper’ tools you find in 3D modellers such as Blender.

The dxfhomography transformation is 100% reversable, passing the transformed object through the dxfhomography tool results in the original object.

This is experimental, somebody ought to add the same functionality to Blender.

Update (September 2026), there is now a Blender extension that implements this transform called Homography Cage
