Authors: Cevat Yerli and Anton Kaplanyan

This keynote was presented at the High Performance Graphics Conference 2010. We want to share our vision and future trends in real-time computer graphics in games. This keynote raises some classic problems as bandwidth, deferred lighting and h/w issues along with the new trends, as server-side rendering and perception-driven graphics.

Besides that, the history of Crytek games and chronology of engines is briefly described as well as new trends in games content and style.

This I3D 2010 paper is a result of collaborative research with Carsten Dachsbacher. The LPV technique was extended to support secondary occlusion and multiple bounces. The propagation scheme is improved and compared to similar Discrete Ordinate Methods. Also this paper describes many additional application and implementation details.

Presenter: Tomas Neumann (Senior Audio Programmer)

At the Audio Boot Camp of GDC2009 Tomas was asked to join a session with Jason Page (Audio Manager R&D SONY) about technical audio development. In the presentation Tomas explains 10 rules he derived from his daily work, which can lead to a safe and risk free production in the field of Audio.

This presentation about audio development explains how Sound Designers can guarantee by using modern tools, streamlined production pipelines, and middleware, to control the last step in the full implementation process. Only then the audio can end up in the final game, which got initially designed.

Software construction is an exercise in managing complexity, more so with the spiralling complexity required by modern games. Automated Testing is an industry proven methodology to deliver more reliable complex software, with a fighting chance to do it on time and on budget. And having fun doing so. Crytek is spearheading this idea in the game industry with its flagship title, and now sharing the experience with you: best practices, potential pitfalls, To-Do’s and No-No’s will be shown with real examples of unit testing game code using its proprietary testing framework and tools. Functional Testing and acceptance testing will also be touched on as a viable way of describing and checking game design requirements. And take automated testing to the next level.

This is a SIGGRAPH 2009 talk from "Advanced Real-time Rendering Course" about new ligting technique in CryEngine 3. The new technique called "Light Propagation Volumes" is used for Global Illumination and Massive Lighting, which significantly improves the lighting quality. The concept and its implementation are explained in the paper. Slides from the talk with talk notes as well as the video are provided.

In CryEngine 3 the renderer is now even more powerful because we added deferred lighting as new engine features. We deliberately decided not to go for a classic deferred shading approach. This has implications on content generation, performance characteristics and implementation. In this presentation we are sharing our experience.

The presentation is describing all major graphic techniques that are available in the CryEngine2. Here we describe the properties and why they are in the engine in that form. All techniques work well together and provide a good solution for current and near future generation of graphics hardware.

The presentation delivers an insight into the challenges of creating levels in a variety of unique open environments

A virtual texture is a mip-mapped texture used as cache to allow a much higher resolution texture to be emulated for real-time rendering, while only partly residing in texture memory. In this Siggraph 2008 presentation we will be discussing technical implications on engine design due to virtual textures use, content creation issues, results, performance and image quality.

Tangent space is a useful mathematical tool, it’s the base for efficient per pixel shading and compressed normal maps. In this presentation we discuss properties and design decisions of the free code we developed. More details can be found in the ShaderX4 article chapter 2.2.

Synopsis: As a follow up to "Real-time Atmospheric Effects in Games" from SIGGRAPG 2006 this presentation expands the catalogue of atmospheric effects implemented in CryEngine2 (Distance Clouds & Underwater Light Transport for Ocean Shading). Additionally, it provides solutions to issues typically encountered with deferred rendering approaches.

Synopsis: The original CryEngine already utilized a lot of the newly introduced features in DX9 to improve rendering performance and visual fidelity. This presentation sheds some light on what’s been used, how it’s been integrated and the gotchas found along the way. Specifically, it’ll cover SM 2.x/3.0, Shader Precaching, Geometry Instancing and HDR Rendering.
