OSG:开头篇 介绍
一.OSG简介
二.OSG配置编译
OpenSceneGraph-3.6.2 : http://www.openscenegraph.org/index.php/download-section/stable-releases/
3rdParty_VS2017_v141_x64_V11_small.7z : http://www.openscenegraph.org/index.php/download-section/dependencies/
OpenSceneGraph-Data-3.4.0.zip : http://www.openscenegraph.org/index.php/download-section/data/
可能发生的错误:
1.更改CmakeList.txt
set (CMAKE_PREFIX_PATH "osg源代码路径")
2.3rdParty第三方库只编译32位即可
3.VS2010安装目录下的VC->bin中的cvtres.exe,把它重命名,例如我的做法是cvtres[backup].exe。具体原因自行百度COFF和LNK1123。
三.OSG组成模块
OSG主要包含4个库:OSG核心库(Core Library) OSG工具库(NodeKit) OSG插件库 OSG内省库(osgIntrospection)
1.OSG核心库
osg库:基本数据类,负责提供基本场景图类,构建场景图形节点(节点类 状态类 绘制类 向量和矩阵类),一些包含程序特定功能类(命令行解析和错误调试信息等)
2.OSG工具库
3.OSG插件库
4.OSG内省库
