• Lab 1 report

Lab 2

Complete the XNA 3D Tutorial. This tutorial is in the form of a video that walks you through the creation of a 3D game.

Assignment 2

Create a new 3D model of a ship in Blender or other 3D modeling software and add this into the game as another enemy ship. Note: the ship can be something trival, such as a box. However, the ship should be textured with a UV map.

Modify the missiles in the 3D game so they home in on enemy targets. Tune the homing algorithm and other aspects of the game to make the game play more enjoyable.

Demonstrate your solution to an instructor in a lab session. (Due end of week 3)

Classroom Discussion

• 3D models
• Model space, world space, view space, screen space
• Homogeneous coordinates
• Column vectors (OpenGL) versus row vectors (XNA)
• Linear transformations: scaling, rotation, translation
• Euler ("oiler") angles
• Buffered input mode versus immediate mode input
