Project #2

Implements an interactive 3D lamp.

Requirements:

• The title must be of the form "Your Name [Your Passcode]".
• Viewing (See example projection.c)
  • Use perspective projection.
  • When the window is resized, the image should not be distorted.
  • Provides zooming in/out feature by changing the "field of view" parameter changed by '+'/'-'.
• Render a desk and some objects on top.
  • Render a desk (size 8x8) using small quads (about 128x128) to show the spot light effect accurately. (See the example gouraud.c.)
  • Render some objects in the scene as you want. (The demo contains a sphere and a teapot.)
  • Assign various material properties to each object. (See the OpenGL example teapots.c.)
• Render a desk lamp.
  • The lamp is composed of various movable parts.
  • Each part can be selected by pressing keyboard '0'~'5'.
  • When selected, each part should be rendered in solid red (not shaded) with edges in white. (See the example polyoffset.c.)
  • The 'base' of the lamp is selected by pressing '0'. When selected, the base is translated by the arrow keys.
  • The 'base joint' is selected by pressing '1'. When selected, the joint is rotated by pressing left/right arrows.
  • The 'lower joint' is selected by pressing '2'. When selected, the joint is rotated by pressing up/down arrows.
  • The 'middle joint' is selected by pressing '3'. When selected, the joint is rotated by pressing up/down arrows.
  • The 'upper joint' is selected by pressing '4'. When selected, the joint is rotated by pressing up/down arrows.
  • The 'head joint' is selected by pressing '5'. When selected, the joint is rotated by pressing left/right arrows.
• Lighting
  • Set the global ambient light with RGB (0.2, 0.2, 0.2).
  • Set the sun light (directional light) with
    • direction (1,-1,1)
    • ambient (0,0,0,1)
    • diffuse (0.5,0.5,0.5,1)
    • specular (0.2,0.2,0.2,1).
  • Set the lamp light as a spot light with
    • ambient (0,0,0,1)
    • diffuse (1,1,1,1)
    • specular (1,1,1,1).
    The direction and cut-off angle of the lamp can be dynamically set.
    • The direction is set by the transformation of the parts of the lamp.
    • The cut-off angle of the spot light can be changed by Page Up/Down keys.
    • The cut-off angle needs to be indicated by a wireframe cone.
