Background technology
Along with the development of computer technology, three-dimensional scenic is used and is more and more come true from concept, such as 3D game, virtual navigation, dummy emulation system etc.Three-dimensional scenic generally all is the three-dimensional design engine implementation that provides by means of the third party, in numerous three-dimensional picture engines, OGRE(Object-Oriented Graphics Rendering Engine, the object-oriented graphics rendering engine) as the three-dimensional picture render engine of increasing income, take full advantage of Object-oriented Technique, make the 3D software implemented convenient, thereby be widely applied.At present, what OGRE was successful is applied in a plurality of three-dimensional simulation projects, comprises game on line and some commercial three-dimensional artificial projects, such as virtual digit city, overpass system etc.
Yet the developer of OGRE d engine does not use Chinese as their first language, so the OGRE d engine directly do not support Chinese, has just reserved certain routine interface.At home, all all can run into the problem how realization Chinese efficient and true to nature marks in the 3D scene based on the constructed virtual scene of OGRE, therefore, how under the 3D of OGRE scene, to realize the Chinese mark and can guarantee operational efficiency, become most important.
The method that realizes the Chinese mark in traditional three-dimensional scenic mainly contains following several scheme:
Scheme one, utilize the rendering intent of 2D, literal is rendered on the 2D layer on the 3D layer, usually utilize CEGUI(Crazy Eddie ' s GUI) storehouse, a kind of general UI(User Interface, user interface) storehouse, combine with the 2D interface layer that OGRE provides, therefore can on the layer of 3D scene, play up again the layer of a 2D to be used for display text more, this scheme is simple, and can easily utilize the 2D prior art to process Chinese character and demonstration, but literal is fixed on the 2D layer, little nearly large variation far away can not be arranged along with moving of camera lens, thereby have certain application limitation;
Scheme two, come Chinese display (OGRE own literal output also be this method of usefulness) by pinup picture, namely prepare a very large picture, draw full Chinese character on the picture, be placed in the resource file and load, need to revise Ogre::Font, Ogre::FontManager, three classes of Ogre::TextAreaGuiElement during loading, navigating to the Chinese character position in the picture, the application limitation of the method in can solution one, it is more true to nature that literal is shown.Yet this scheme need to consume a large amount of video memorys, and the literal size differs too large with respect to the bitmap size ratio, causes font single, is not suitable for amplifying dwindling, and amplifies and can see shade and mosaic when dwindling;
Scheme three, utilize TTF(TrueTypeFont) vector font library, the unicode of all Chinese characters coding is loaded in the configuration file of OGRE, because the method is utilized vector font library (namely coming descriptive text with Points And lines), therefore need to amplify when dwindling at character size, only need to amplify corresponding multiple to the Points And lines of all these literal gets final product, the phenomenons such as mosaic can not occur, just in time solve the font defective in the scheme two.Yet, adopt this scheme also to have certain defect, because this scheme is before inputting word information, need to create background process and carry out the initialization of fontlib, and Chinese characters in common use have more than 20,000, adding Chinese font commonly used has tens of kinds, so the initialization procedure efficient of this scheme when starting is very low, this obviously can not satisfy practical application.
