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. -
Game Engine Review
Game Engine Review Mr. Stuart Armstrong 12565 Research Parkway, Suite 350 Orlando FL, 32826 USA [email protected] ABSTRACT There has been a significant amount of interest around the use of Commercial Off The Shelf products to support military training and education. This paper compares a number of current game engines available on the market and assesses them against potential military simulation criteria. 1.0 GAMES IN DEFENSE “A game is a system in which players engage in an artificial conflict, defined by rules, which result in a quantifiable outcome.” The use of games for defence simulation can be broadly split into two categories – the use of game technologies to provide an immersive and flexible military training system and a “serious game” that uses game design principles (such as narrative and scoring) to deliver education and training content in a novel way. This talk and subsequent education notes focus on the use of game technologies, in particular game engines to support military training. 2.0 INTRODUCTION TO GAMES ENGINES “A games engine is a software suite designed to facilitate the production of computer games.” Developers use games engines to create games for games consoles, personal computers and growingly mobile devices. Games engines provide a flexible and reusable development toolkit with all the core functionality required to produce a game quickly and efficiently. Multiple games can be produced from the same games engine, for example Counter Strike Source, Half Life 2 and Left 4 Dead 2 are all created using the Source engine. Equally once created, the game source code can with little, if any modification be abstracted for different gaming platforms such as a Playstation, Personal Computer or Wii. -

Advanced 3D Visualization for Simulation Using Game Technology
Proceedings of the 2011 Winter Simulation Conference S. Jain, R. R. Creasey, J. Himmelspach, K. P. White, and M. Fu, eds. ADVANCED 3D VISUALIZATION FOR SIMULATION USING GAME TECHNOLOGY Jonatan L. Bijl Csaba A. Boer TBA B.V. Karrepad 2a 2623 AP Delft, Netherlands ABSTRACT 3D visualization is becoming increasingly popular for discrete event simulation. However, the 3D visu- alization of many of the commercial off the shelf simulation packages is not up to date with the quickly developing area of computer graphics. In this paper we present an advanced 3D visualization tool, which uses game technology. The tool is especially fit for discrete event simulation, it is easily configurable, and it can be kept up to date with modern computer graphics techniques. The tool has been used in several container terminal simulation projects. From a survey under simulation experts and our experience with the visualization tool, we concluded that realism is important for some of the purposes of visualization, and the use of game technology can help to achieve this goal. 1 INTRODUCTION Simulation is the process of designing a model of a concrete system and conducting experiments with this model in order to understand the behavior of the concrete system and/or evaluate various strategies for the operation of the system (Shannon 1975). Although the simulation experiment can produce a large amount of data, the visualization of a simulated system provides a more complete understanding of its behavior. In the visualization, key elements of the system are represented on the screen by icons that dynamically change position, color and shape as the simulation evolves through time (Law and Kelton 2000). -

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. -

Deze studio wilt een nieuw project starten voor een 3D spel in een HyperText Markup Language 5 (HTML5) browser die intensief gebruik zal maken van artificiële intelligentie (AI) en Web Graphics Library (WebGL). Na onderzoek via een requirements-analyse van verschillende mogelijkheden van game engines komen we terecht bij twee opties namelijk Unity 5, die Rusty Bolt al reeds gebruikt, of de Unreal Engine 4, wat voor hen onbekend terrein is. Qua features zijn ze enorm verschillend, maar ze voldoen elk niet aan één voorwaarde die Rusty Bolt verwacht van een game engine. Zo biedt Unity Technologies wel een mogelijkheid om software te bouwen in de cloud. De broncode van Unity wordt niet openbaar gesteld, tenzij men er extra voor betaalt. Deze game engine is dus niet volledig open source in tegenstelling tot Unreal Engine 4. We vergelijken dan verder ook deze twee engines, namelijk Unity 5 en Unreal Engine 4. We tonen aan dat deze engines visueel verschillen van features, maar ook een andere implementatie van de AI hanteren. -
