This article introduces an optimization approach for modeling and rendering impossible figures. Our solution is inspired by how modeling artists construct physical 3D models to produce a valid 2D view of an impossible figure. Given a set of 3D locally possible parts of the figure, our algorithm automatically optimizes a view-dependent 3D model, subject to the necessary 3D constraints for rendering the impossible figure at the desired novel viewpoint. A linear and constrained least-squares solution to the optimization problem is derived, thereby allowing an efficient computation and rendering new views of impossible figures at interactive rates. Once the optimized model is available, a variety of compelling rendering effects can be applied to the impossible figure.

Flocking simulates the motion of a flock, which is well known as artificial life algorithms. By using the flocking, we can express the motion of the group such as fishes, birds, or crowded animals in computer graphics. In order to render flocking more realistically, we have devised a method that adds some dynamic conditions into flocking computation. The additional external force and the moving coordinated cameras within the three dimensional space can help us to apply the flocking algorithm into 3DCG system more extendedly and easily. In this paper we provide our algorithm and approaches.
