Abstract: A method of efficiently creating an animation image data file is provided. Components of a device are modeled using a 3-D CAD system and filed. After file format conversion, the file is imported to application software for animation. The components are then assembled, a camera angle is selected, and the transparency of the components is specified. A video file is created and included in an HTML file which is a completed animation data file. A clear perspective of the device comprising complicated components can be obtained because some components created with 3-D CAD system are rendered transparent using the application software for animation.
