3D Virtual Campus

Introduction

• Graphics were my first interest
• This topic was an obvious choice

3
Project Description

• 3D environment using C and OpenGL
• Using arrow keys, user can walk around and view
  the external features of the buildings on
  Westminsters campus

Look-at position
Eye position

Main Goal Expandability

• No realistic chance for complete product
• Want others to be able to
• Add new buildings (campus center)
• Simply add/modify properties
• Add functionality

5
Scene Description Language (SDL)

• Separates building data from code
• Simpler to understand

• Problems
• No standard
• Errors abound
• Unnecessary info

• Were some nice things (transformation matrices)
• In retrospect, better to create own rather than
  modify existing SDL

6
Useful features

• Perspective view
• Plane class (for use in drawing grass)
• Shading/Color
• Overhead View

7
Three Main Features

• Motion
• Building Class
• Preventing view from going into buildings

8
Motion

• Forward/Backward
• Left/Right Turns
• Left/Right Strafe
• Math involved
• Standard methods
• Trig and unit vectors

Building Class

• Started with cube
• Added way to display roof
• Fenestration
• How to display it
• How to represent it
