Odin Development Group

β€˜RF Online’ is a 3D MMORPG with SF background. ODIN Development Group was the primary team responsible for the creation of the R3 Engine and RF Online.

In early stage of RF Online, Odin Development team took 5 years to develop this game, when average development period of online games is less than two years at that time. Led by Mr. Jang (Jang Un-il / Oneal Jang) from the beginning to 2006.

R3 Engine

The R3 engine (R3 Technology TM) was developed at CCR itself and is optimized for online RPG games from the design. It is superior in performance, function, and use compared to 3D MMORPG which partially remodeled foreign FPS game engines such as Unreal, Quake Engine.

Expression of wide space became possible by reinterpreting and approaching the BSP structure which was appropriate for indoors that was used in the Quake engine or other foreign engines but not for outdoors. The world and characters can be managed through quick, simple structures both indoors and outdoors.
The Multi layered Materials System enables dynamic expression on the map based on BSP. Very dynamic, various expressions are created from technologies including Skybox that supports beautiful, extensive expressions, vertex shade for high quality features, Pixel shade, Volumetric effects for brilliant special effects, Enhanced Particle System, Dynamic Light, and a weather system. This makes an appeal as an exciting game to users.

The R3 engine shows high quality, high frames not only to high-feature users but also to low-feature graphic cards (Geforce 2 MX, Radeon 7500). (A high frame rate is shown even in the thick forest (P-III 550,Geforce2MX 32M)

Since the basic structure was set based on the chip set of the next generation which supports TnL from early designs, the present Geforce-FX, Radeon-9800 shows the best quality and performance. R3-Engine2.0 is currently under operation. Faster speed and higher quality are planned to be presented in Geforce-fx, Radeon-9800, and the 3D card that will be released in the future. Keep your expectations high!

Speed is one of the strongest functions of R3 engine. 20 million polygons can be managed per second at maximum. The game would not affect the number of polygons in the background. However, the speed is not slowed down at all, although brilliant effects cover the screen from background+character+effects and other dynamic factors based on fast speed which made the most of the acceleration functions of 3D hardware. This speed will support the genuinely large-scaled RF battle of planets.

R3 Engine written in C++ programming language.
