What it takes to make a game?

Asset pipeline and game engine

Cooperation

  • Each aspects supports

the other ones in one way or the other

  • Tasks are divided up

so that their execution can be parallelized

  • Maximize output

  • Getting more similar and similar as time

goes on

○ Asset pipelines are getting closer (physical shading for example) ○ Game development still has extra steps and considerations.

  • Both for good and bad...

Visual development processes in games and movies

Environment

  • Design

○ Story/Idea ○ Sketch ○ White/grey box ○ Gameplay scripting ○ Maintaining working state as art comes in ○ Fix bugs

  • Art

○ Story/Idea ○ Gather reference ○ Concept art creation ○ Basic shape modeling ○ Final art creation

■ Model (high and) low poly ■ (Bake) ■ Unwrap ■ Texture and shade

○ Import assets ○ Add lighting, effects, ambient sounds etc... ○ Maintain working state as gameplay evolves ○ Fix bugs

Characters

Character development cycle example from Team Fortress 2: 1. Character silhouette 2. Interior shapes 3. Model sheet 4. 3D Model 5. Character Skin 6. Final Character in game

  • Very time

consuming

  • Hand animation

versus motion capture

  • Canned versus

procedural

Animation

Vertical slice

  • Small polished section
  • f game
  • All aspects polished
  • Helps to find problems

earlier

  • A chance for all

departments to work together

  • Bechmark for the rest of

the game

  • Potential time sync

Game engines

  • Game engine is a set of software

responsible for the game mechanics

  • Runtime vs Tools

Layers

slide-19
SLIDE 19

Hardware

  • Desktop

○ A lot of configurations to handle

  • Mobile / embedded

○ Still growing market

  • Dedicated

○ Military simulators

  • Name some differences!
slide-20
SLIDE 20

Examples

  • Input

○ touchscreen vs mouse vs gamepad vs keyboard

  • Screen resolution

○ mobile devices vs desktop ■ 640x960 vs 4096x2160

  • Memory
slide-21
SLIDE 21

Driver management

  • Driver - Low level software component
  • Driver operates as a delegate between

upper layers and hardware

slide-22
SLIDE 22

Operating system

  • Win / OSX / Linux
  • Embedded

○ Weird ones… In the bus ○ Mobile ■ Android ■ iOS ■ Windows Phone ■ BB, Tizen?

slide-23
SLIDE 23

Engine core

  • Support for components

○ Scripting ○ Graphics component ○ Input / Output component

  • Initialize behaviour between components
slide-24
SLIDE 24

Resource manager

  • Getting data to the game

○ Asset manager ■ Loading data from HDD, Discs ○ Streaming system ■ Open world

  • Open World vs Indoor
