Global Deformation:

Write a program that implements global deformation with at least the following operations: taper, twist, bend. Program should be written in OpenGL and the GUI in fltk.

You have a lot of flexibility in terms of how sophisticated you want your program and/or interface to be. For example, some features to consider are: wireframe, flat, or smooth shading; orthographic or perspective projection; material and lighting effects; different data object(s) to manipulate; individual deformations or cumulative deformations; undo operations; linear or user-specified transformation functions; etc.

Aside from the text, the main source of reference is: Barr, A.H., Global and local deformations of solid primitives SIGGRAPH '84, July 1984, vol.18, (no.3):21-30.

Deliverables:

• Program: include source, executable, and makefile or equivalent. Submit these electronically on teach.ic using:
  submit cmps260-ap.w01 prog1 files-to-submit
• Documentation: user guide (max 5 pages). Include description of features supported, also include some color snapshots from your program. The color printer in 237BE is called color.
• Demo: on 2/15/01, allow about 5-10 minutes per project to show off your program. We have access to SGI's, Suns, and Windows NT box. Give me advance notice so that we can test out your program before the demo.

Relevant Info:

• FLTK

  The fltk package is in the /projects/public/fltk directory on the cse machines. An executable of fluid for windows is available by clicking: fluid.exe . Some sample opengl/fltk programs are available here. Best place to start is with simple .

• DEMO

  An SGI demo of global deformation is available here .
  Disclaimer: some functionality does not seem to be entirely correct.

• DATA

  Bunch of graphics models are available here .
