Shading in Valve's Source Engine
Advanced Real-Time Rendering in 3D Graphics and Games Course – SIGGRAPH 2006 Chapter 8 Shading in Valve’s Source Engine Jason Mitchell9, Gary McTaggart10 and Chris Green11 8.1 Introduction Starting with the release of Half-Life 2 in November 2004, Valve has been shipping games based upon its Source game engine. Other Valve titles using this engine include Counter-Strike: Source, Lost Coast, Day of Defeat: Source and the recent Half-Life 2: Episode 1. At the time that Half-Life 2 shipped, the key innovation of the Source engine’s rendering system was a novel world lighting system called Radiosity Normal Mapping. This technique uses a novel basis to economically combine the soft realistic 9 [email protected] 10 [email protected] 11 [email protected] 8 - 1 © 2007 Valve Corporation.

In order for our characters to integrate naturally with our radiosity normal mapped scenes, we used an irradiance volume to provide directional ambient illumination in addition to a small number of local lights for our characters. With Valve’s recent shift to episodic content development, we have focused on incremental technology updates to the Source engine. For example, in the fall of 2005, we shipped an additional free Half- Life 2 game level called Lost Coast and the multiplayer game Day of Defeat: Source. Both of these titles featured real-time High Dynamic Range (HDR) rendering and the latter also showcased the addition of real-time color correction to the engine. -

One focus has turned to adding more humanlike characteristics into computer game agents. Machine learning techniques are being used scarcely in games, although they do offer powerful means for creating humanlike behaviors in agents. The first person shooter (FPS), Quake 2, is an open source game that offers a multi-agent environment to create game agents (bots) in. -

What Is Game Engine Architecture
What Is Game Engine Architecture What Is Game Engine Architecture 1 / 2 In any case, game engines are the workhorses of modern videogame development As you'd expect, there are plenty of engines out there, from very well-known names like Quake and Unreal, that developers and publishers can license at considerable expense, through to in-house proprietary engines created by studios specifically for their own titles.. Quite a few of the in-house engines have no public personality and thus are not included on this list.. CryENGINEAs Seen In: Far Cry, Crysis, Crysis Warhead, Crysis 2, Aion: Tower of Eternity It didn't take long for the German developer Crytek to make a name for itself.. These are what turn good creative ideas into great gameplay Note: It is important to understand that not all developers are vocal about their game engines and instead play their cards close to their chests. T A L K E R to usher in a new generation of PC gaming, Crytek beat them all to the punch with a stunning, tropical set FPS game powered by its own brilliant CryENGINE.. 14320288/red-dead-redemption/videos/reddead_trl_wildwest_50509 html;jsessionid=1oyv5eo9s1id0' target='_blank'>Click here to see just how stunning Red Dead Redemption looks..

This paper addresses localization from a game development perspective by studying the state of tool support for a localization work in general purpose game engines. Using a systematic mapping study, the most commonly used game engines and their official tool libraries are studied. The results indicate that even though localization tools exists for the game engines included in the study, the visibility, availability, and functionality differ. Localization tools that are user facing, i.e., used to create localization, are scarce while many are tool facing, i.e., used to import localization kits made outside the production pipeline. 1.

Real Shading in Unreal Engine 4 by Brian Karis, Epic Games
Real Shading in Unreal Engine 4 by Brian Karis, Epic Games Figure 1: UE4: Infiltrator demo Introduction About a year ago, we decided to invest some time in improving our shading model and embrace a more physically based material workflow. This was driven partly by a desire to render more realistic images, but we were also interested in what we could achieve through a more physically based approach to material creation and the use of material layering. The artists felt that this would be an enormous improvement to workflow and quality, and I had already seen these benefits first hand at another studio, where we had transitioned to material layers that were composited offline. One of our technical artists here at Epic experimented with doing the layering in the shader with promising enough results that this became an additional requirement. In order to support this direction, we knew that material layering needed to be simple and effi- cient. With perfect timing came Disney’s presentation [2] concerning their physically based shading and material model used for Wreck-It Ralph. Brent Burley demonstrated that a very small set of material parameters could be sophisticated enough for offline feature film rendering. He also showed that a fairly practical shading model could closely fit most sampled materials. Their work became an inspiration and basis for ours, and like their “principles,” we decided to define goals for our own system: Real-Time Performance • First and foremost, it needs to be efficient to use with many lights visible at a time. 1 Reduced Complexity • There should be as few parameters as possible.
