CS 445: Computer Graphics

• Lab 2: Introduction to OpenGL/JOGL (3 weeks)
  • Tues: continue to work on Lab 1, part 3.
  • Thurs: look at student work for part 3. Begin Lab 2, part 1.
  • Look at lab examples for OpenGL code structure: methods main, init, , reshape.
• Ray Tracing - what we didn't cover: transforming shapes, efficient implementations (e.g bounding boxes etc), photon mapping, etc
• Useful Links
  • www.opengl.org
  • JOGL
  • Netbeans plugin for JOGL
  • Nate Robbins OpenGL tutorials. Note, these are also on enfuzion in our class folder.
  • Reference pages for 2.1
• Look at ShaderSupport Code - what can your graphics card do?
• Pipeline:
  • Geometry Pipeline
  • Hardware View
• OpenGl Primatives
• Projections and Viewing
  • Types
  • Look at Nate Robbins projection.exe (gluPerspective, gluLookAt)
  • OpenGL Projection Transformations: glFrustum(), gluPerspective(), glOrtho(), gluOrtho2()
• Summary of OpenGL functions for setting up Transformations
