Weight: 15 %.
Collaboration: None. If you discuss this assignment with others you should submit their names along with the assignment material.
Instructions: Submit your assignment at SEASNET. Make sure you use the following file names: cie.cpp, cie.dsp for question 1 and scene.cpp, scene.dsp for question 2. If you program on unix submit ONE Makefile for both.
Submit a printed version too.
Start working on it early. You will not have time to do it at the last minute.
1. Colour [6 marks] Write a program that displays the CIE chromaticity diagram, as an image made up of pixels. The diagram should show the following:
a. [3 marks] The triangular gamut of colours that can be displayed by a monitor whose RGB phosphors have the following chromaticities:
|
Phosphor |
x |
y |
|
R |
0.628 |
0.330 |
|
G |
0.258 |
0.590 |
|
B |
0.1507 |
0.060 |
Colors outside this gamut should appear black.
b. [3 marks] The curve of pure spectral colors, with a white pixel at each 5-nm wavelength increment.
Use the template code found at www.cs.ucla.edu/~pfal/courses/cs174/2002s/coursework/
2. Animation [20 marks] Write a program that shows an animated scene. Your scene should include a combination of hierarchical objects that move around. Required elements:
a. [4 marks] At least one two-level hierarchical object (e.g. human arm).
b. [4 marks] At least one polygonal object modeled vertex by vertex (i.e. you provide the vertices, and normals directly).
c. [4 marks] At least one procedural texture.
d. [4 marks] 360 degrees camera fly around.
e. [4 marks] Creativity. (Story, colors etc).
Use the template code found at www.cs.ucla.edu/~pfal/courses/cs174/2002s/coursework/
3. Clipping [5 marks]
a. [3 marks] Use the Sutherland-Hodgman algorithm to clip this polygon on this rectangular window:
