CPSC 324, Spring 2001                         Information For Second Test
-------------------------------------------------------------------------

The second test for this course will be given on Thursday, April 26.
Since the previous test, the main topics that we have covered have been
hierarchical graphics, lighting and materials, and textures.
Here is a list of some of the terms and ideas that you should be familiar
with for this test:

  hierarchical graphics models
  scene graph
  traversal of a scene graph
  use of glPushMatrix and glPopMatrix to implement hierarchical models
  vectors
  normal vector
  unit normal
  homogeneous coordinates
  matrices
  transformation matrices
  lighting
  specular reflection
  diffuse reflection
  relation of normal vector to reflection
  ambient lighting
  lights and materials in OpenGL
  glEnable(GL_LIGHTING)
  glEnable(GL_LIGHT0), ...
  glEnable(GL_NORMALIZE)
  glMaterialfv(<sides>,<property>,<value>)
  glLightfv(<lightnum>,<property>,<value>)
  glPushAttrib(GL_LIGHTING_BIT) and glPopAttrib()
  emissive, diffuse, and specular colors
  position of a light (in homogeneous coordinates)
  directional lights (suns) and positional lights (lamps)
  display lists
  glGenLists(<number-of-lists>)
  glNewList(<listnum>,GL_COMPILE_AND_EXECUTE)
  glEndList()
  glCallList(<listnum>)
  textures
  2D image textures
  texture coordinates for 3D objects
  (s,t) coordinates on a 2D texture
  procedural textures
  3D textures
  bump maps
  texture modes: how can textures be applied to an object?
  indexed face set representation of polygonal meshes

  general ideas encountered in blender:
     bezier curves
     keyframe animation
     modeling with extrusion and lathing
     the "alpha" color value and transparency
     keyframe animation and IPO curves
     path animation
     "tracking" animation
     particle systems
     spotlights
     environment maps
  (you will not be asked questions about blender's interface)
