I was casually browsing the web today when I stumbled upon an animation blogger demonstrating how to make a transition animation where a pentagram is transformed into a character, which I found quite interesting.
The author first conceived a transformed form in the shape of a pentagram, then fused the girl’s image into the pentagram and drew the girl’s dynamics against the shape of the pentagram.
The movement is made to fit the shape of the pentagram as closely as possible. Keep contrasting the transformations.
The droplets of water waving in the girl’s hand grow larger and the girl’s form eventually liquefies into water.
The transition is perfect, with only eleven frames to achieve in a very smooth way. Well worth studying.
