What The Unity?‣ Games Mainly 3D (with acceleration), but 2D as well‣ Apps Augmented Reality apps Medical apps Architectural 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 File Change Detection‣ 3D objects including textures, bones, animations and UV Watches for ﬁle changes and automatically updates assets

Texture Import‣ Formats JPEG, PNG, GIF, BMP, TGA, IFF, PICT... and PSD‣ Video & video textures Camera texture Ogg Theora MOV, AVI, ASF, MPG, MPEG, MP4VIDEO transcoded‣ Automatic generation Mip-Map, Height Map to Normal Map, Bitmap to Bump Map PVRTC

Audio Import‣ Live preview‣ 2D & 3D audio Sound sources & listeners One sound listener attached to scene camera Multiple sound sources Environment settings Room settings Doppler 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 library MOD, 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 JavaScript‣ Languages C# C# JavaScript Boo‣ Scripts as components Boo‣ Prefabs‣ Rich API

Visual ScriptingUseful 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 Unity MonoDevelop Xcode

Unity Remote‣ Realtime preview‣ Mobile device features transferred to Unity Multitouch Accelerometer / 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-in and 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 hardware Fill rate RAM Drawcalls‣ Batching Dynamic batching Static batching‣ Game budget

Lightmapping — Beast (before)

Lightmapping — Beast (after)

Batching & Caching‣ Occlusion Culling & Penumbra‣ Light-mapping / Beast‣ Terrains Now on mobile devices Tree Creator

Asset Store‣ Buy 3rd assets 3D Models Characters, environments, vehicles, vegetation... Textures Shaders, bricks, fabric, metal, nature, paper, roads, wood... Audio Music, sound FX, ambient sounds... Example projects Tutorials, templates, demos, games...

Asset Store‣ Buy 3rd assets Editor extensions Animation, audio, modeling, painting, utilities... Scripting AI, GUI, network, effects, physics... Particle systems‣ Build and sell your own and be rich :]

Future: Unity 3.5‣ HDR rendering with gamma correction‣ Native level-of-detail support‣ Shuriken A completely curve driven particle effects system‣ Integrated GPU proﬁler‣ Pathﬁnding and crowd simulation built in‣ Integrated version control support for Perforce and SVN
