DrawThreadPerContext模式下根据场景中摄像机的数量设置_endDynamicDrawBlock变量的值,这个阻塞器用于在每个渲染器都渲染完毕之前阻塞主进程的运行,以免用户对数据的更新动作于动态对象的渲染动作产生冲突。 这个numViewerDoubleBufferedRenderingOperation是根据摄像机获得的。 初始为0 接下来即DrawThreadPerContext模式下需要执行...
GraphicsContext::createGraphicsThread()创建线程时,得到一个osg::GraphicsThread线程对象 而使用Camera::createCamera创建线程时,得到的是osg::OperationThread对象,它是GraphicsThread的父类。 可见osg::Opera… 阅读全文 赞同 2 添加评论

1.osg::Operation -osg::Window 的回调函数 2.osg::Camera::DrawCallback 3.继承osg::Drawable 前两种方式以frame为单位进行渲染 第三种方式(osg::Drawable)以节node为单位进行渲染 对于节点渲染(osg::Drawable),一个极好的例子是osgteapot. class Teapot : public osg::Drawable ...
同时,渲染器派生子Operation类,也就是说它属于一种用户操作,可以追加到操作线程OperationThread和GraphicThread中,进而可以在图形设备或相机节点的线程中运行,完成多线程环境下的渲染接口操作。 渲染器并没有直接将场景节点传递到裁剪访问器,也不负责记录渲染树或状态树的节点数据,它自动创建并保存的osgUtil::SceneView对...
这样不仅可以提高图形刷新的速度,还可以方便用户为某一特定的GraphicsContext设备添加特殊的处理动作,方法是使用osg::GraphicsContext::getCompileContext获取后台图形上下文,再使用GraphicsContext::add函数向其中追加osg::Operation对象,类似的例子可以参看osgterrain。
