Topics for the Week of Sept 27, 2010
CS 445: Computer Graphics

• Reading: You should be reading relevant chapters in the text book. See readings on schedule but also poke around the book. Matrix transformations can be found in Chapter 4 (for the moment, start at 4.7) and Appendix C.

• Labs:

  • Complete Lab 2: Introduction to OpenGL/JOGL, part 1
  • Begin of Lab 2: Introduction to OpenGL/JOGL, part 2

• Continue discussion of the Pipeline:

  • Geometry Pipeline
  • Hardware View (This picture was created by Mike Bailey, OSU)
  • View Frustum

• More mathematics

  • Matrix representation of transformations: translation, scale, rotation, shear, reflection, projection
  • composition
  • Rotation/scale around a point other than the origin
  • Determinants, inverses
  • Homogeneous coordinates

• Practice problems

• OpenGL

  Matrices in OpenGL
  • Modelview Matrix
  • Projection Matrix
  • Setting matrices: gluLookAt, gluPerspective, glMatrixMode, glLoadIdentity, glPushMatrix, glPopMatrix
  • Other OpenGL functions:
    • storing/specifying geometry: immediate mode (deprecated), display lists(deprecated), vertex lists, vertex buffers.
    • Wave program, Algebraic surfaces

• Summary of OpenGL functions for setting up Transformations

  Modeling transformation modelview matrix	glTranslate, glRotate, glScale
  Viewing transformation modelview matrix	gluLookAt
  Projection transformation projection matrix	glFrustum, gluPerspective, glOrtho, gluOrtho2
  Viewport transformation	glViewport
