第一节：游戏引擎导论

游戏引擎是一个很大的系统

历史

Early Age of Modern Game Engine

• Quake

• Unlike what Doom engine did previous, the Quake engine offered full real-time 3D rendering and had early support for early 3D acceleratiokn through OpenGL

引擎类型

• Engine

• Middlewares

What's Game Engine

• Technology Foundation of Matrix

• Productivity Tools of Creation

• Art of Complexity

• Infinite Details of the World

Complexity of Simulation

• Combat

• Interaction

• Reaction

• Net Sync

• Prediction

• Render

  • Animation

  • Motor

  • Camera

  • Effect

  • Cloth

  • Sound

• Game Engine is Way beyond Rendering

• God with Limited Power in Realtime

Toolchain for Creators

• 庞大的工具体系

• 适配不同专业的人群

Developer Platform

• For Programmer

  • Expandable API interface allow programmers to define various of gameplay without changing the core.

• For Studio

  • Collaborate hundreds of developers with different disciplinary work smoothly together.

  • 为了艺术家，设计师，程序员设计工具

• Update the Engine on the Fly

  • 不断完善

  • 不断升级

  • 需要前向兼容

  • The Creator and Operator of this Ugly Monster.
