What The Unity?

‣ Games

Mainly 3D (with acceleration),but 2D as well

‣ Apps

Augmented Reality appsMedical appsArchitectural visualizations

Platforms

‣ Desktop

Windows, OS X

‣ Game consoles

Playstation, Nintendo Wii, Xbox

‣ Mobile devices

iOS, Android, Union

‣ Web

What Unity Does?

Workflow

‣ Project structure

‣ Drag & Drop

Visual programming

‣ Browsers

Textures, objects, sounds, scripts, animation clips etc...

‣ Snapping

Importing 3D Assets

‣ Import without a 3rd party app

FBX, OBJ, 3DS, Collada DAE

‣ When a native app is needed

Maya, Blender, Modo, Cinema 4D,3D Studio Max, Cheetah 3D

Automatic FileChange Detection

‣ 3D objects including textures,bones, animations and UV

Watches for file changesand automatically updates assets

Texture Import

‣ Formats

JPEG, PNG, GIF, BMP, TGA, IFF, PICT... and PSD

‣ Video & video textures

Camera textureOgg TheoraMOV, AVI, ASF, MPG, MPEG, MP4VIDEO transcoded

‣ Automatic generation

Mip-Map, Height Map to Normal Map,Bitmap to Bump MapPVRTC

Audio Import

‣ Live preview

‣ 2D & 3D audio

Sound sources & listeners

One sound listener attached to scene cameraMultiple sound sources

Environment settings

Room settingsDoppler effect

Filters – DSP effects

High-pass / low-pass, distortion, chorus / echo / reverb

Audio Formats

‣ Music

MP3 & Ogg Vorbis (depending on platform)

‣ Sounds

AIFF, WAV

‣ Trackers

FMOD libraryMOD, IT, S3M, XM

‣ Streaming

Ogg Theora & Ogg Vorbis streaming from network

Font Import

‣ TrueType

‣ 3rd party scripts

‣ Font sheets

Editors

‣ MonoDevelop

‣ Microsoft Visual Studio

‣ TextMate

‣ any other editor

MonoDevelop (OS X / Windows)

Microsoft Visual C# (Windows)

TextMate (OS X)

Unitron (OS X)

Components & OOP

‣ Languages

C#

JavaScript

Boo

‣ Scripts as components

‣ Prefabs

‣ Rich API

JavaScript

C#

Boo

Visual Scripting

Useful for designers and not so nerdy programmers

Kismet / uScript

Play / Pause

‣ Debugging & Profiling

Instant launch, recompilation in background

‣ No need to recompile

Changes visible immediately

‣ Debugging and Profiling

UnityMonoDevelopXcode

Unity Remote

‣ Realtime preview

‣ Mobile device features transferred to Unity

MultitouchAccelerometer / gyroscope

‣ Lower FPS and visual quality

Asset Server

‣ Team cooperation, shared assets

‣ Versioning

‣ Needs a free server,but a separate client license

Linux, Windows, OS X

‣ Can be installed locally

Asset server

Conflict diffing in FileMerge

Surface Shaders

‣ A lot of Shaders both built-inand on Asset Server

‣ Do your own shaders

‣ Mobile shaders

Fullscreen Postprocessing Filters

‣ Most interesting filters

Bloom + Lens Flare, DOF, Sun Shafts, Color Correction, Glow, SSAO, Motion Blur, Noise, Twirl, Vortex

‣ Hardware consumption

‣ Not supported on mobile devices

Physics

‣ NVIDIA PhysX

GPU hardware accelerated

‣ Rigidbodies

Physical materials

Triggers

‣ Colliders & collisions

Box, Mesh, Sphere, RayCasting, Wheel colliders...

Physics

‣ Joints

‣ Softbodies

‣ Cloth simulation

Animation‣ Animation editor

‣ Animation clips

‣ Bones, IK

‣ Animation & Pose blending

Animation

‣ Biped editor

‣ Mixamo

Respect the Platform

‣ Optimization

Mobile hardwareFill rateRAMDrawcalls

‣ Batching

Dynamic batchingStatic batching

‣ Game budget

Lightmapping — Beast (before)

Lightmapping — Beast (after)

Batching & Caching

‣ Occlusion Culling & Penumbra

‣ Light-mapping / Beast

‣ Terrains

Now on mobile devices

Tree Creator
