Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples, but the protection scope of the present invention is not limited to the following specific examples.

[0023] This embodiment uses the DirectX software development kit to independently develop a game engine named KAN3D, specifically including a rendering engine built on the basis of Direct3D, an input system built on the basis of DirectInput, a sound system built on the basis of DirectSound, processing collisions and Physical system for movement, animation system and simple artificial intelligence system, scene management system. The engine also uses basic scripting capabilities and a graphical user interface (GUI) system of command and property scripts. The GUI system is used to create the main menu, load scenes, etc. For the architecture diagram of the above game engine, s...

Abstract

The invention discloses an LOD (Level of Detail) technology-based scene rendering method. The method comprises the steps of determining a square rendering terrain; segmenting the rendering terrain by utilizing a quad-tree; updating and traversing the rendering terrain; repairing a cracked terrain; and the like. An LOD technology is a technology for adjusting grid data precision by stage, and the grid data precision is relatively coarse for triangles relatively far away from a point of sight and is relatively fine for triangles relatively close to the point of sight. After use of the LOD technology, the large scene rendering effect is better improved in efficiency and effect, and the game running speed is increased.

Description

technical field [0001] The invention relates to the technical field of game engines, in particular to a field rendering method based on LOD technology. Background technique [0002] A game engine is a collection of high-level codes that can be used as a basis for developing your own games. Modern game engines already hide the details and specifications of the underlying implementation from those who use it. The game engine includes: rendering engine, physics engine, sound engine, scene management, etc. A game engine itself is just a collection of smaller engines. There isn't a precise definition of a game engine or what it covers. For a video game, its game engine must at least include a rendering engine and an input engine, which is necessary, otherwise, it cannot be called an interactive game. [0003] Microsoft's DirectX SDX is a commonly used software development kit for developing game engines. The white hair kit includes 6 components: ① DirectDraw: use the method o...
