Morphable guidelines are a 3D structure that helps users achieve better face warping on 2D portrait images. Faces can be di cult to warp accurately because the rotation of the head a↵ects the shape of the facial features. I bypass the problem by utilizing the popular Loomis 'ball and plane' head drawing guideline as a proxy structure. The resulting 'morphable guidelines' consist of a simple 3D head model that can be reshaped by the user and aligned to their input image. The vertices of the model go on to act as deformation points for a 2D image deformation algorithm. Thus, the user can seamlessly transform the face proportions in the 2D image by transforming the proportions of the morphable guidelines. This system can be used for both retouching and caricature warping purposes, as it is well-suited for both subtle and extreme modifications. This system is advantageous over previous work in face warping because our morphable guidelines can be used on a wide range of head orientations and do not require the generation of a full 3D model.

We introduce artist Lucy Pullen's Double Meandering Algorithm, first in its original form as a pen-and-paper drawing algorithm and then as a procedurally generated animation. We utilize a chain of cubic Bézier curves to represent the characteristic spiraling line, assigning each control point according to a pseudo-randomized algorithm. The resulting curves are then animated segment by segment, reflecting the artist's process of creating the pen-and-paper drawing. By digitizing the Double Meandering Line drawing, we can also reveal the process of creation through animation, granting us the ability to exhibit a fundamental part of the drawing that is lost in the traditional pen-and-paper presentation.
