With the development of computer technology and related scientific theories, the production of three-dimensional electronic maps has gone through three stages: Line-drawn topographic maps, solid-type topographic maps, and three-dimensional realistic topographic maps.
3D terrain simulation is one of the most basic and important technologies in the development of visual systems. There are two types of terrain

Years later, when I was not busy with my work, I studied bottom-terrain generation. At present, the research on basic static terrain generation has come to an end. The following is a review:

Ogre generates terrain through the configuration file, greatly improving the flexibility of terrain generation. This section briefly analyzes the meaning of each configuration item in the terrain configuration file (

Write your ideas First:To make a simple terrain roaming, consider developing directly in WW, or find a development component in the form of a control.The biggest expectations are:1. Support for Google SketchUp, fast and intelligent three-dimensional modeling2. Design patterns do a good job, preferably in the form of components, and then develop the application3. Performance better, for indexing technology, memory management, etc.4. Client independent
One way to achieve terrain is to use a grid. Each grid has a quadrilateral, which does not share vertices and does not support the level of detail. However, a grid can have multiple layers of texture, which is suitable for 2.5D angle-of-view games, such as Warcraft 3 and tianlong
The other is the mainstream 3D Game practices, sharing vertices and dles. The disadvantage is that the texture layers of a terrain

Use Terrain Scene Manager for Terrain Management in versions earlier than 1.71, and then use ogre terrain system.
The relationship between terrain and paging must be understood
Although the version of the Dragon is not good, but retains the original, read the book when the best combination of the original and the Dragon's translation. In addition, if there has been experience in terrain generation to read this book some help, this book introduces the professional outdoor terrain development, very comprehensive introduction.Only a personal summary, may not be suitable for netizens
I started the project only when I changed my new company as a client, and the engine was using ogre. It was so happy that I could study ogre at work.
The first step is to make the terrain editor.
Using Qt as the interface, MFC completely abandons it ~~~
For the time being, I only focus on ogre.Code, The QT interface is thrown to the team members and then combined.
Because it is a fixed-angle 2D/2.5D game
