Cross M allows both loading and controlling the real-time data constantly (stand gameplay in a row) for realization under restrictive condition of system resource. Cross M represents high speed rendering, smooth animation, various screen effects and sound effects for giving an impression of velocity and hitting. Cross M includes a separate thread for routine loading and controlling the data from disk. Cross M realizes multi-thread by utilizing a separate thread. It could load and control to stand users' gameplay in a row. As applying ROAM (Real-time Optimally Adapting Meshes), it can represent broad land with optimized Polygons per frame because ROMA makes simple like lands far from a point of view and make a minute realization like short distance lands. If background is only displayed by color map, color of lands in short distance can be blotted and squashed. For solving the defects, Cross M represent elaborate graphic with detail map, overlapped color map. Skinning help a joint part of animated characters be shown natural and mild. Moreover, it adds the reality of character. Cross M can represent smooth transitions between different actions or blend with two actions. Utilize cloth animation by physical accounts for expressing items naturally like cloak. Represent screen effects which are the same level with CG (motion blur, reverse, glow and distortion etc), Weather effects (rain and snow) and realistic water reflection effects by pixel and vertex shader of the latest graphic card. Provide sound effects with 3D sound. Provide streaming background sound with "ogg" codec of low volume and high quality. We designate optional place in the background map and support of treating specific events in that area.( This theory is also used to provide background sound when users get into special area.) WorldCreator, editing instruments of background, makes a basic shape of lands by using fractal. It is possible to edit high and low of lands like drawing a picture with WorldCreator. It can also create realistic lands fast and easily. Support plug-in that change proper form from 3DS MAX to Cross M engine. (Majority of graphic designers use 3DS MAX). Support effect editor that makes out and edit like magnificence effects on RYL Online.
