Design Brief for Reflection Visualization

This project designed and written by Becky Bowen, Maphra McCoy and Kathy Wright for the Scientific and Technical Visualization II and III Workshop, June 22-24, 1998.

I. Problem Identification and Definition: Design a visualization which explains the Law of Reflection.

Important questions to answer:

1. Definitions of reflection, incident ray, reflected ray, normal, angle of incidence, angle of reflection, regular reflection, and diffuse reflection.

2. What do illustrations of items look like, such as: reflection, regular reflection and diffuse reflection?

3 . What are examples of reflection?


II. Research and Review of Literature: Reference: Physics: Principles and Problems by Zitzewitz and Neff. P. 347-351.

III. Identification of Appropriate Scientific Visualization Design Criteria: This project lends itself well to a power point presentation to show title and defnitions and as an organizer for 2D and 3D visualizations. In addition, 2D static drawings out of a paint program and 2D and 3D dynamic visuals from True Space will work well as visualizations for this project.

IV. Plan of Work: Draw slides for power point presentation

1. Title slide for reflection.

2. Definitions of law of reflection and law of refraction.

3. 2D static of incidence ray and reflected ray.

4. 2D static of angle of incidence and angle of reflection.

5. 2D dynamic of law of reflection.

6. 3D dynamic of pool table on the law of reflection.

7. 2D static of regular reflection.

8. 3D dynamic of pool balls with smooth surface.

9. Picture of smooth surface.

10. 2D static of diffuse reflection.

11. 3D dynamic of pool balls with rough surface. (if time permits, graph reflected light vs. incidental light)

12. Picture of a rough surface.

13. Put together power point presentation.

V. Expected outcomes: We will develop a power point presentation containing a series of illustrations and animations showing reflection using the action of pool balls to represent light rays. Regular reflection and diffuse reflection will be discussed (time permitting, analyze the brightness of the reflected light on various surfaces will be included.)

VI. Evaluation criteria: Success will be measured by the following criteria:

VII. Student Written Evaluation of the Design and Production Process: When creating drawings in Paint and TrueSpace, all drawings should be drawn to optimize time used. Then drawings should be imported to power point and the presentation should be developed all at the same time for best optimizations of time.
