Human Forearm Computer Animation Based on Fluid Structure Interaction
We use Fluid-Structure Interaction (FSI) to simulate the movement of a human forearm. When liquid pushes the upper half of the forearm, anchored at the elbow, the entire forearm rotates upward. A real human arm uses a complex muscular process for movement, involving chemical reactions, energy retrieval and expenditure, among other processes. This makes realistic muscular simulation of human arm movement very difficult to achieve, and slow to run, making it unreasonable for animators of movies and video games to use in most situations. In addition, other realistic arm movement methods such as motion capture are often used, but are time consuming and costly. Other less realistic, but faster methods, such as Bezier curves, are commonly used for their speed and cost effectiveness. Bezier curves can be aesthetic when used by talented artists, but can take much time if high precision is needed. Being a simulation based on a natural process, but easier and faster to achieve than muscular interaction, FSI may be a possible in-between for the long and costly motion capture, and the inaccurate and requiring of artistic talent Bezier curve methods. In this project, FSI is explored as a possible method for this in-between, setting the way for more explorations and refinements of the idea in the future.
