CMSI 371
COMPUTER GRAPHICS
Spring 2008
Assignment 0313
Spring Break is the perfect time for hunkering down and working through an additional level of detail and
planning for your graphics project; this assignment hopes to give it a little structure.
Not for Submission
Read Chapters 10 and 11 in Angel for additional
information, details, and alternatives for 3D
object/scene modeling.
For Submission
Flesh out your graphics project a little bit more by
creating (and submitting) the following documents:
•A use case diagram for your project
•A structural diagram for the data needed by your
project (i.e., its model), including the approach
that you plan to use for the 3D or geometric in-
formation that will be displayed onscreen
•A “user control” diagram that specifies how each
of your project’s use cases will be triggered (e.g.,
keypresses, mouse activities, etc.)
Note how these documents essentially define the
model and controller of your graphics project; most
of the remaining work focuses on the view, which
makes sense since this is, after all, a computer
graphics course.
You may use any tool that you find effective, in-
cluding hand-drawn sketches — just make sure
that your diagrams are clear and readable. Thus,
submission for this assignment is on hardcopy.
If you do produce these diagrams electronically, by
all means commit them to CVS, under /projects/
cmsi371/doc.
For Submission (Extra Credit)
You will receive extra credit if you supplement
your design documents with enough initial code to
constitute a substantial beginning toward the im-
plementation your model and controller.
Your code must show a clear correspondence to
the plans laid out by your documents — this is no
longer a throwaway prototype, but the foundation
for your actual project. Focus on definitions and
implementations of the data structures and event
handlers specified by your use case, structural, and
user control diagrams. View-related code (i.e., the
display() function and all other directly-supporting
code) may wait.
I reserve the right to determine, based on the func-
tionality and degree of difficulty of the committed
code, whether your submission constitutes a “sub-
stantial beginning” (and thus whether you do get
the extra credit).
How to Turn it In
Commit your work to /projects/cmsi371, using
whatever directory structure you feel is needed to
expedite development.
