INSTRUCTOR: Prof. Drew Browning; Director, Design Visualization Lab
EMAIL: drew@uic.edu; PHONE: 996-9463; OFFICE HOURS: Tues/Thurs 11-1 Rm 3386 AA

GRADUATE TEACHING ASSISTANT:  Terry Jun; EMAIL: tjun2@uic.edu

COURSE GOAL : To gain a working knowledge of the fundamentals of 3D computer graphics, from surface modeling to rendering, and to integrate these skills into the design process.

MATERIALS NEEDED : One zip disk. Although you will be working from your own directory on the DVL LAN (Local Area Network), it is your responsibility to save your work to removable media after each work session. FILES MAY BE DELETED BY STAFF AS NECESSARY FOR MAINTENANCE REASONS!

TEXT : No text will be assigned for this class. You will be expected to take notes in lectures, read the course notes linked from this page and use the on-line documentation within MicroStation. There are many good books on MicroStation at major book stores. Check out the MicroStation web site for current books:
http://www.bentley.com/academic/bookstore/index.htm

GRADE: Your grade is based on attendance, participation in class critiques and the following assignments:

1. COORDINATE MODEL (5%)
2. RADIUSED BOX (15%)
3. 1. WIRE FRAME RADIUSED BOX (5%)
   2. SURFACED RADIUSED BOX (5%)
   3. RENDERED RADIUSED BOX (5%)
4. SIMPLE HANDHELD PRODUCT (20%)
5. FREE FORM THUMBNAIL SKETCHES (10%)
6. FINAL DESIGN (50%)

Assignments are presented in class on due date. Late assignments will be lowered by one letter grade for each class meeting they are late. All assignments are to be saved to floppy disk and turned in at final critique. Examples of assignments can be found on the DVL web site at: http://bucky.aa.uic.edu/DVL. Videotapes and articles on computer graphics and CAD/CAM presented through out the semester. If you have a documented disability and wish to discuss academic accommodation please talk to me during my office hours.

Syllabus

Week 1:, Week 2:, Week 3:, Week 4:, Week 5:, Week 6:, Week 7:, Week 8:, Week 9:, Week 10:, Week 11:, Week 12:, Week 13:, Week 14:, Week 15:, Week 16:

Week 1:

• A. Introduction to the class. history of CAD; introduction to pc systems;
• B. Intro to cad and ustation interface.

Week 2:

• A. Review essential operating system procedures. Working in 3D computer space, preparing to model, basic 2D ustation commands.
  IN CLASS EXERCISE: BUILD SIMPLE WIREFRAME BOX AND STORE TO DISK..
  Important note: Always work from the computer's hard disk, NOT YOUR ZIP OR FLOPPY DISK! A typical work session will involve:

1. 1. copying your current project from zip or floppy disk to your directory (if you also work on the project elsewhere).
   2. continuing working on project.
   3. copying the new or modified project files back to your zip or floppy disk (rename with current date appended).
   4. making a backup copy to a separate disk

• B. Basic 2D primitives and tools continued.

Week 3:

• A. Coordinate systems: model, screen, local; element placement, view control.
  GIVE : ASSIGNMENT 1: COORDINATE MODEL. Build X,Y,Z coordinate model (wireframe) and label positive end of each axis (due 4a).
• B. Command syntax for ustation; help; element transformation and modification.
  GIVE : ASSIGNMENT 2: RADIUSED BOX. Asymmetrical box with radiused edges and corners and through hole. Example at DVL web site. Wireframe (Due 5a); Surface model (Due 5b); Rendered image (Due 6b)

Week 4:

• A. COORDINATE MODEL DUE
  Organizing and separating elements by style, color, level and groups. Intro to surface modeling: ruled surface, surface of projection and surface of revolution
• B. Intro to rendering.
  GIVE ASSIGNMENT 3: HANDHELD PRODUCT. Model simple handheld product. wireframe, surfaced, rendered. (Due 10b). Examples at DVL web site. Bring several products to class for discussion. (due 7b)

Week 5:

• A. WIREFRAME RADIUSED BOX ASSIGNMENT DUE
  Detailed ustation commands
• B. SURFACED BOX DUE.

Week 6:

• A. Changing elements levels. Separating Surfaces to Other Levels: PROCEDURE
  Better rendering, saving a bitmapped file. Rendering the Radiused Box: PROCEDURE
• B. RENDERED BOX DUE.

Week 7:

• A. Detailed surfacing options: building the radiused box efficiently. copy, mirror, chain, surf of rev, surf by edges.
• B. BRING SIMPLE HANDHELD PRODUCTS TO CLASS FOR REVIEW

Week 8:

• A. 3D primitives: slab, cylinder, cone, etc.
• B. IN CLASS EXERCISE: BUILD TEA POT WITH SPOUT. Bezier curves, tubular surfaces, skin surfaces.

Week 9:

• A. IN CLASS EXERCISE: BUILD RADIUSED BOX WITH ADVANCED TOOLS. Surface of projection, fillet surface. Beware of surface normals, tolerance and radius size vs. surface size.
• B. IN CLASS EXERCISE: BUILD CAR SEAT WITH COMPLEX CURVED SURFACES. Use surface by section or network.

Week 10:

• A. Detailed organizing data: level names and groups, saved views, chains and graphic groups. Using Saved Views: PROCEDURE
  GIVE ASSIGNMENT 4: THUMBNAIL SKETCHES.. Create a matrix of 8 freeform thumbnail sketches. (due 11b). Examples at DVL web site. The second set will be based on feedback from critique of first. (due 12b)
