November 2004 - February 2007

.

• The Project Realism Engine (PREngine) was my first game engine

• It was developed while I was at university, as a side project for the first 2 years. In the final year it was used in its first game, called Boy Racer

• Written in C++ and DirectX 9.0c, using Microsoft Visual Studio.NET 2005, and FX composer 1.8 for HLSL shader development

• It went through many revisions and started out as just a learning experience with DirectX, but evolved to contain:

  • A physics engine (using Newton Game Dynamics)
  • Lua scripting support
  • XML parser
  • 3D surround sound
  • Complex scene graph (which arranges scenes by material, instance, or distance from camera, for max rendering speed on DirectX 9 hardware)
  • Resource manager (loads .x meshes, .dds textures, .wav sounds, and .fx HLSL effects)
  • Keyboard, mouse, windows controller, and Xbox 360 controller support
  • User interface (UI) system
  • Video player (using DirectShow)
  • Full HLSL shader support (that automatically scales for a range of graphics cards; from shader model 1.1 to 2.0b)

Effects Demo August 2007

• Displays 3 boxes with the following shaders on:

  • (Left) Texture Mapping
  • (Middle) Bump mapping with specular highlights
  • (Right) Parallax mapping with specular highlights

• All shaders scale from pixel shader version 1 through to 2b (Set shader quality in settings box)

• Shaders written in HLSL, using FX Composer 1.8

Physics Demo July 2007

• Uses Newton Game Dynamics for the Physics

• Uses the PREngine to load and draw the scene

• Shows a sphere being projected into a tower of blocks. The physics simulation can be paused and restarted at any time
