C4 Engine Version 4.0 Released
C4 Engine version 4.0 is now available to all licensed users. This is easily the largest and most important release ever made in the history of the C4 Engine, and it includes many major performance improvements, new features, and usability enhancements. The details can be found in the release notes, but here are the highlights:
• The built-in physics system has received a complete overhaul and is now considerably faster as well as more accurate. In particular, the constraint solver is multithreaded and takes advantage of all available cores for maximum performance.
• Some new internal scene organization structures have been added to the engine, and they provide a huge reduction in CPU processing time for very large and highly dynamic worlds.
• The PlayStation 4 rendering code has been completely rewritten at a level much closer to the metal and is now significantly faster.
• Major changes have been made to the lighting and shadowing systems in the engine, and these provide big performance increases in addition to higher-quality rendering.
• Several changes have been made to the World Editor in order to provide more functionality and better usability.
With the release of version 4.0, we have also consolidated the different types of licenses that previously existed into a single low-cost license that applies to everybody. The C4 Engine can now be licensed for a mere $88.00 per user, and this includes a full year of free upgrades.

OpenGEX Preliminary Specification Released
A preliminary specification for the Open Game Engine Exchange (OpenGEX) format has been released along with binaries and source code for the 3D Studio Max export plugin.

OpenDDL Data Language Introduced
As part of its effort to develop a new cross-platform model exchange format, Terathon Software has created a general-purpose, human-readable data description language called OpenDDL. An informal specification has been posted on the OpenDDL website, and it is free to use by anyone for any purpose. This language arose as the foundation for the Open Game Engine Exchange (OpenGEX) format, which will be released soon as an open standard with open-source export plugins for 3D Studio Max, Maya, and Blender. The entire project was made possible by a successful Indiegogo campaign earlier this year.

C4 Engine is a Front Line Award Finalist
In the December 2011 issue of Game Developer Magazine, C4 Engine has been named as one of the five finalists in the game engine category for the 14th annual Front Line Awards! A big thanks goes out to all of the users who helped nominate the engine so it could be acknowledged in this venue. The winners in each category will be announced in the January 2012 issue.
Eric Lengyel to Speak at GDC 2012
The creator of the C4 Engine, Eric Lengyel, will be giving a one-hour lecture at GDC 2012 in March entitled “Fundamentals of Grassmann Algebra”. This session will provide a thorough introduction to the basic geometric properties of the wedge product and multivectors as they would be used in game development. Particular focus will be given to the geometric manipulation of points, lines, and planes in generalized homogeneous coordinates. It will also explain how seemingly quirky behaviors in everyday graphics programming, such as the transformation of a normal vector by the inverse transpose of a matrix, arise naturally when viewed from a larger algebraic context.
C4 Engine Version 2.7.1 Released
C4 Engine version 2.7.1 is now available to licensed users. This release contains a number of miscellaneous improvements, driver workarounds, and bug fixes.
C4 Engine Nominated for Front Line Award

C4 Engine Version 2.7 Released
C4 Engine version 2.7 is now available to licensed users. This release includes several new features and many improvements to existing systems.
As shown in the example to the right, version 2.7 includes new voxel-based blob particle rendering capabilities. The engine uses a parallel fixed-polarity marching cubes implementation to triangulate blobs (a.k.a. metaballs) in real time using all available processor cores.
Version 2.7 also includes a substance registration system that lets substance types be assigned to materials and physics shapes. Theses substance types can then be accessed through collision functions and physics contacts to distinguish among various substances like metal, wood, or stone. Some uses include playing different footstep sounds and applying different bullet hole decals depending on the type of substance.
Finally, this version includes a new animation cue track that can be edited in the Model Viewer tool. Cues can be added to existing animations so that they trigger a callback when the animation passes specific points. These cues can be used to signal things like when to play footstep sounds, when to throw or shoot projectiles, and when to apply damage to a target.
