A General Procedure for the Construction of Mirror Anamorphoses
Résumé
Anamorphoses are distorted images needing to be seen from a special point of view in order to reconstruct the correct image (perspectival anamorphosis). In catoptric anamorphosis, a mirror is used to restore the original image. We describe an effective procedure, using a ray-tracer software, for defining, testing and building general catoptric anamorphoses. Users can define the mirror's shape, the surface on which the distorted image lays, and set the observer's point of view. The method can be used to virtually render and test anamorphoses designs or to output a distorted image in any suitable image format that can be printed at any scale, in order to obtain a real size version of the anamorphosis. We exhibit examples with different mirrors and different distorted image locus.
