Problem
Based on a 2D height chart, you want to create a terrain and draw it in an efficient way. Solution
First, you need a height chart that contains all the height data used to define the terrain. This height chart has a fixed number of two-dimensional data points. We call it the width and height of the terrain.
Obviously, if you want to create a

The terrain system of hl2 is an alternative terrain system. It uses displacement map technology instead of the popular heightmap technology, the original intention of using the displacement map technology is to maintain consistency with the BSP Technology in the framework, because the smallest rendering element in the BSP is the surface, the limitation of surface is that all vertices must be on the same pla
2.6 detect collision between cameras and models, walls or terrain
You want to check whether the camera is near the object to prevent it from passing through the object. Solution
To perform a collision detection between the camera and the model, you should represent the camera as an surround ball and use this surround ball to check the collision with the model's surrounding ball or the surrounding box. For user-defined mesh, such as a wall or
Step 1: Create a new project.Open the Unity3D software and it will automatically load the "Bootcamp Demo" project file we opened last time. Don't worry about it. After the software is opened, click -->. In the pop-up dialog box, find and enter the folder address for creating the project, or click "select a folder address" next to it. Note: the folder of the created Unity3D project cannot be used as the folder of the newly created Project. Otherwise, an error is reported because the file cannot b
The loading and application of DEM in learning WW is very important for the development of three-dimensional GIS plug-in based on WW. I have always wanted to focus on and collect relevant learning materials, did not begin to study it before, mainly because I did not see the elevation of the application function in WW, feel unable to cut. I spent my time yesterday afternoon and this morning looking for research pointcuts! The essence is to find out how to view elevation in WW. (Think back now, fe
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

Introduction
In many games, what we encounter is not an endless plain, but an uneven terrain. This section describes how to build a terrain.
Height chart
The terrain has different heights. In 3D graphics, we use a height chart to express the ups and downs

This article, followed by the previous one, focuses on the details of how to build the earth grid in a highly-detailed way. At this point, the globe creates a corresponding Tileterrain class for each slice (globesurfacetile), which is used to maintain the relevant logic of the terrain slice; and then, in Requesttilegeometry, The Tileterrain requests the terrain data that should be sliced.

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:

This thought "OpenGL game programming" in the terrain generation algorithm is very tall, but in recent days because in the view of "3D terrain programming", the whole book is about the terrain-related content, and "OpenGL game programming" in the terrain algorithm is the simplest kind, only "3D

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.
