The initial scene is divided into tiles. Each tile has a randomly generated object.

There are six possible rendering modes for objects: light only, texture only, light + texture, light + bump, light + texture + bump, cubemap.

Objects have three drawing modes: fill (triangle), line, and point.

A point light source follows the camera to the nearest tile and rotate around the center of the tile.

Usage

  • Hierarchy tree:
    • Displayed at the left of the page.
    • Selected primitive have <- on the right.
  • Selected primitive:
    • After creating a new primitive, it becomes the current selected primitive.
    • Use up/down arrow key to go up/down in the hierarchy tree.
    • Use left/right arrow key to move among the siblings.
  • Creating new primitives:
    • Click buttons and enter parameters to create a new cube/cylinder/sphere/model.
    • Newly created primitive will be the child of the selected primitive and placed at (0, 1, 0) position relative to the selected primitive.
  • Deleting the selected primitive:
    • Click Delete button.
    • Use Delete key.
  • Moving:
    • Use the key to control the camera:
      • w: move forward
      • s: move backward
      • a: rotate left
      • d: rotate right
      • q: rotate down
      • e: rotate up
    • Use the key to move root forward/backward/left/right/up/down.
      • W: forward
      • S: backward
      • A: left
      • D: right
      • Q: up
      • E: down
    • Click Translate button, then hold and move mouse left/right to move on the current axis.
  • Rotating:
    • Click Rotate button, then hold and move mouse left/right to rotate about the current axis.
    • For camera only:
      • Use P/p to adjust pitch.
      • Use Y/y to adjust yaw.
      • Use R/r to adjust roll.
  • Scaling:
    • Click Scale button, then hold and move mouse left/right to scale on the current axis.
  • Setting the current axis to translate/rotate/scale:
    • Click X, Y, Z buttons.
  • Setting the selected primitive's color:
    • Pick a color and click Set Color button.
  • Setting the light's color:
    • Pick a color and click Set Light Color button.
  • Setting the drawing mode:
    • Click Fill, Line, Point buttons.
  • Setting the rendering mode:
    • Click Light, Texture, Light+Texture, Light+Bump, Light+Texture+Bump, Cube Mapping buttons.
