1. Story
This animation tells a magic story, where a funny man appears. He gets on an airplane and takes off. During the flight, he flies over a mountainous area and drops a ball into a body of water, which causes a wave. Then, he flies near a clock tower and his airplane explodes. However, when we look at the clock tower, the clock disk opens and he appears inside of the clock tower.
2. Technique
a. Physics-based Animation The ball falling and water wave are animated using physical description. Euler integrator is used for the falling ball and Verlet integrator is used for the water wave.
b. Scientific Visualization The mountain and cloud are made by random function and the color of the mountain is mapped according to the height. The river color is mapped according to the magnitude of the gradient and trees are made by cones.
c. Texture Mapping The title flag is made by texture mapping. A two dimensional image is used and changed to simulate the waving flag.
d. Volume Texture Mapping The two tone color of the airplane is made by volume texture mapping.
e. Bump Mapping In order to simulate a real lawn, bump mapping is used. The normals of the lawn is changed a little bit by random function.
f. Image Techniques In the second scene, the first scene image fades out and the second scene image fades in gradually.
g. Fire work In order to simulate the bomb explosion, bomb size and color are changed as time passes.
