Ultimate 3D

Ultimate 3D, also referred to as U3D, is a free 3D engine designed for use with Game Maker. It currently uses DirectX 8.1 and is programmed by Christoph Peters in .
Notice
As of July 1, 2008, Christoph Peters has announced that future Ultimate 3D versions will not offer interfaces to be used with Game Maker anymore. Ultimate 3D 3.0, which is currently being developed, will be based upon DirectX 10 or even 11 and may become the base for a complete game making solution.
Features
Ultimate 3D was originally designed to be an easy-to-use 3D engine for the user friendly game creation software Game Maker, which only supported 2D rendering at the time of the first Ultimate 3D versions, and the early versions' features were quite limited in the beginning. Ultimate 3D 2.0 beta 1 offered a much wider range of features, which could be used to make advanced 3D graphics. Through the Ultimate 3D effect file format (*.ufx) and the support for post screen shaders new shader effects could be added in a comfortable way. In spite of the big changes, the engine's ease of use, detailed documentations, and good support, especially on the forum, are still important attributes of Ultimate 3D.
Currently, the latest version of Ultimate 3D is 2.1.2 beta. The following is a list of its important features:
* An efficient system for creating primitive geometry
* A model loading system for:
** Animated Anim8or model files, also with bone influences and skin weights (*.an8) <sub>(Scenes are not supported, because the file format description of the *.an8 file format doesn't describe their chunks)</sub>
** Animated 3D Studio Max files (*.3ds)
** Animated Quake II model files (*.md2)
** Animated DirectX model files, also with vertex skinning (*.x)
** Animated Milkshape 3D model files, also with vertex skinning (*.ms3d)
* Vertex tweening, a technique to make frame based animations (as used by *.md2 files) totally smooth
* Lighting and fog system
* Support for sky spheres and sky cubes
* Functions for drawing 2D graphics and texts
* Fully automatic level of detail generation
* Functions to manipulate models in real-time, by changing their geometry data
* Cel-shading for graphics in comic style
* Multi texturing for techniques such as light mapping
* Spherical and cubical environment mapping for reflections
* The Ultimate 3D effect file format for adding custom shader effects
* Support for post screen shaders
* Support for per pixel lighting and parallax mapping
* Support for real-time stencil shadows
* An efficient terrain renderer for big and detailed terrains
* A complex particle effects system
* Support for split screens
* Render to texture and render to cube texture functions
* Math functions for efficient matrix and vector calculations (those can't be done with Game Maker)
* A portal engine for highly efficient culling
* Support for fullscreen antialiasing
* Support for anisotropic filtering
In addition to traditional model support, Ultimate 3D also has its own file format (*.u3d) which comes with password encryption and pre-applied shader and material effects.
Use
Ultimate 3D is used via Game Maker's built-in extension capabilities. A DLL and script library can be downloaded from the Ultimate 3D website and then merged with a Game Maker project to allow use of Ultimate 3D. It is supported in Game Maker versions 5 and later.
In contrast to Game Maker's existing Direct3D functions, Ultimate 3D draws a separate window over Game Maker and renders to it.
Since 2 programs can't render the same portion of the screen at the same time, integrated GM drawing functions can't be used together with Ultimate 3D. That's why U3D also integrates 2D drawing functions.
Community
U3D has an online community. The forum is read by moderators, who answer questions about the engine's mechanics as well as techniques for creating 3D effects.
Games using U3D
A number of games are currently being developed with U3D. At the moment, Edge of Infinity, a MMORPG, is the most popular project in progress. Another game that utilizes Ultimate 3D is an MMORPG entitled: The Warriors Path (which has been discontinued). In addition to this, a game simply known as "Project Data" is currently in the planning stage of development, although details pertaining to the games genre and theme have yet to be disclosed. A fourth game, Project CORE, a Third-Person Stealth Action Shooter, is currently in beta stages.
3D Studio Max Exporter
Users of 3DS Max that have trouble exporting models properly to a format usable by Ultimate 3D will be happy to know that an exporter is currently being made that will allow direct exporting to the engines proprietary *.u3d format. A release date has yet to be announced.
