Due Date	HW to HAND IN	Comments
11-27-01 T	Matrix Transform Math Web Reading	Go to the "First Steps To Animation" web site by Wolfgang Engel and read the tutorial. Ignore the DirectX programming language (it looks like: ConfirmDevice() OneTimeSceneInit() InitDeviceObjects() ). Focus on finding these answers: 1) Identify these graphics terms: vertex, standard transformations, clipping, vertex blending, morphing, animation, skinning, elevation fog, mesh warping, procedural texture coordinate generation such as reflection maps and lighting. 2) Briefly explain these concepts: modelspace, worldspace 3) What is the function of a transform matrix in manipulating 3-D digital images? Give one example of this concept at work.	10 pts
11-28 W	“DIGITAL HUMANS WAIT IN THE WINGS”	Email your answers to these questions.	10 pts
11-29 H	Tour the Computer Animation Web sites	Email the answers to these questions: 1) What process always occurs in the beginning stages of creating CG movies like Toy Story, Final Fantasy, or the Matrix? 2) How does human motion get "captured" for CG characters? 3) What sort of VAB blocks would you need to accomplish the task in #2 with a CCD camera? Please give a block diagram outline of what such a VAB motion capture worksheet might entail. 4) Identify one unique feature from Final Fantasy's: a) Polygon models b) Lighting models c) Hair models	10 pts
11-30 F	Read "How 3-D graphics Work" Handout and answer questions at right	Email the answers to these questions: 1) Mathematically how is a vertex of a polygon described? 2) Describe in a 4x4 matrix the coordinates of any triangle object with one vertex centered on the origin of the 3-D worldspace. 3) What is clipping? Why is it useful? 4) What is the job of a rendering engine? How does this involve matrix transformations? 5) What is z-buffering? 6) How are texture maps used? Why are MIPs maps useful? 7) Why is alpha channel blending useful?	10 pts
12-3 M [Top]	Chapter 5 Review Questions	1) You want to be able to pick out a specific face in a crowd. Assuming that the face must have a minimum of 500 x 500 pixels across it, and the face’s field of view would be 50 x 50 cm. a) what size CCD would you need (in total pixels) if the image was to be taken from the Goodyear Blimp at a height of 500 meters? b) If this is a 24 bit color image (8 bits or 1 byte per color channel, 3 color channels), what would be the number of bytes of memory for 1 snapshot above? c) If the current state-of-the-art is an 8 Megapixel CCD, and the number of pixels is doubling every 24 months, how long would you have to wait in order to accomplish your desired goal as stated above? 2) Make a 6 x 6 matrix that represents an image of a 2-D black square of 2 pixel x 2 pixels, centered in the matrix. What matrix would you multiply this image matrix by in order to translate this square 1 pixel to the right?	10 pts

12-12 W	none	Test over Ch. 4 , 18, and up to 5.3	100 pts
12-14 F [Top]	Part I: Outline of the basic concepts presented in the Mojoworld Theory handout Part I. Spend 40 minutes please.	Outline in Word the handout on the basic concepts that the Parametric Hyperspace rendering engine of Mojoworld is based upon. Your outline should include: > What is a fractal? What makes it particularly good at creating natural-looking planetscapes in real-time? > Explain the 4 basic components of random fractals > What is an octave in fractals? How does changing the number of octaves change the planetscape? > Domain and range of sinusoid functions in 1, 2, and 3-D worlds > What really is "Parametric Hyperspace"? > Perlin & Voronoi basis functions > What is a convolution? Do you think it might be related to a concantenation matrix? > Distinguish between sine, linear, step, and checkerboard convolves > What is spatial resolution? How does changing this change a planet? > What is spatial frequency? What is the Nyquist Limit? > What is a functional fractal? What is an "alias" effect that can come from rendering these fractal algorithms? > How are fractals randomized? Give two examples of this process.	see below
12-17 M	Part II: Outline the remainder of the Mojoworld Theory handout.	Finish outlining the entire Mojoworld theory chapter. After visting the fBM website from 12-10 HW, then add these items to your outline: > How does a procedural texture differ from a texture map? > Why is fBM considered a monofractal? > Identify 5 uses for fBM in CG > What does turbulence have to do with making sophisticated textural renderings? > What is z-buffering? Hint: see your "How 3-D Graphics Work" handout for help. > How many Pentium II CPU clock cycles are required to render procedural textures for the marble surface, wood surface, and simple grass texture based on one octave of noise? Email the finished outline as an attachment to Mr. Rummel It will count as a lab grade.	40 pts
12-18 T	Ken Perlin's "Noise" lecture slides	Walk through Ken Perlin's lecture slides (MIT) below: http://www.noisemachine.com/talk1/ Be prepared to discuss the major concepts (not the deep math) on Tuesday! Watch for > pseudo-randomness > hypertexture > What drove him to develop these methods?	R
