CAP4730: Assignment 2

3D Transforms, Lighting, and Shading

---

Assigned: Wednesday, February 6^th, 2008

Due: Friday, February 29^th, 2008

Objective: Create a 3D virtual world that includes a Cyberware face scan of yourself that tells a story that describes you.

Template to load in the face scans. (assignment2jogl.zip , assignment2opengl.zip <- 2/26 version w/ updated obj reader fix)

From TA: Students should be able to load in their face models with color now. All they have to do is change the 'cube.obj' to 'lastname.obj' when loading models in the main program. Also, I set up a light.

Scene requirements (20 points):

• Create a statue or monument of yourself using a Cyberware face scan. (Its pose should say something about you).
• Provide a hierarchical model that will interact with your statue/monument, such as a helicopter flying around taking pictures, etc.
• Its motion can be automatic or user controlled.
• In the rendering window, display ‘frames per second’

Rendering requirements (30 points:

• Place both omni-directional and spotlights in the scene to appropriately light the environment. The lights should be of changeable colors.
• Allow the user to toggle spotlights in the scene. The spotlights focus should be movable.
• Allow the user to toggle shading (FLAT and Gouraud) using the ‘s’ key.

Interaction requirements (15 points):

• Allow the user to manipulate the view using the mouse.

A. The camera’s view should be centered on the statue’s head.

B. If the user holds down the LEFT mouse button and moves the mouse, the camera should move about a sphere centered at a focus point

C. If the user uses the MOUSE WHEEL or RIGHT mouse button, the camera should zoom in and out

Collision Detection (25 points):

• Have some projectile (e.g. paintballs, rain, cream pies) collide with your monument. The minimum is to do axis-aligned bounding boxes (20 out of 25 points). Object-aligned bounding boxes or per-triangle calculation is worth full points.

Create a webpage that shows off your assignment including screenshots (10 points)

A. Explain how to run and control your program (1 paragraph)

B. Any online models you used.

C. Explain the visual effect of the shading, and explain the tradeoffs between the two approaches. – 5 points

D. Screenshots of your statue/monument, and a picture of you side by side and explain your project

E. link to a .zip file of files required to compile and run your project. Also include a precompiled .exe in your .zip file.

F. Email the TA your webpage (this is equivalent to turning in your project)
