What transformation type best models character morphing?

Character morphing involves altering a character's shape and size, which can include distortion or more complex changes beyond simple movement or rotation. The best model for this process is a dilation or a complex combination of transformations because it allows for variations in size and shape while maintaining proportionality in the transformation.

Dilation specifically can change the size of a character while keeping the overall relational structure intact, which is essential in morphing. Additionally, using a combination of transformations—such as rotations, translations, and reflections—enables a more nuanced and intricate shape change typical in character morphing. This complexity captures the fluid nature of morphing that cannot be achieved through rigid transformations alone, which preserve the size and shape throughout the movement.

Transformations like translations and scaling can contribute to the morphing process, but they may not adequately cover all aspects of physical changes required in morphing. Therefore, the option that encompasses both dilation and the potential for combining various transformations aligns most closely with the essence of character morphing.
