Final Project Graphics

Stage 1: Work Features Implemented

• MDL function: light
  • Allow for multiple lights
  • Edited vary for moving lights
• New Primitive Shapes:
  • Wedge
  • Square pyramid
  • Cylinder
  • Cone:

Details About Features

• Adding Multiple Light Sources
  • MDL file syntax for light: light name r b g x y z
  • If you define a light with the same name twice, the later light definition will replace the original
  • The first light is always called "firstLight"
• Changing Behavior of Vary
  • Using vary to move lights
  • New function: move_light
    • MDL syntax: move_light [name] x y z [knob]
    • move_light name x y z
      • Moves the specified light x units in the x-axis, y units in the y-axis, and z units in the z-axis
    • move_light x y z
      • Moves all lights x units in the x-axis, y units in the y-axis, and z units in the z-axis
  • New Primitive Shapes
    • Wedge
      • Starting Point: left-bottom-front vertex (x, y, z)
      • add_wedge( polygons, x, y, z, width, height, depth )
    • Square pyramid
      • Starting Point: top vertex (x, y, z)
      • add_pyramid( polygons, x, y, z, width, height, depth )
    • Cylinder
      • Starting Point: center of bottom of cylinder (cx, cy, cz)
      • Generates an upright standing cylinder with center aligning with the y-axis
      • add_cylinder(polygons, cx, cy, cz, radius, height, step)
    • Cone:
      • Starting Point: center of bottom of cone (cx, cy, cz)
      • Generates an upright standing cone with center aligning with the y-axis
      • add_cone(polygons, cx, cy, cz, radius, height, step)

Details on Implementaion in Our Animation

• Multiple lights are moving around
• Wedge used for dino tail
• Square pyramid used for cactus spikes
• Cylinder used for cactus
• Cone used for party hat
• Can better view shapes and moving light in shapesdemo.mdl

Development Log
