这就是渲染到纹理Render To Texture(RTT)要实现的目标。 在OE的拾取器代码osgEarthUtil/RTTPicker.cpp中可以看到渲染到纹理所必要的一些类及其用法,如142行所示: RTTPicker::getOrCreatePickContext(osg::View* view) {for(PickContextVector::iterator i = _pickContexts.begin(); i != _pickContexts.end(); ...
实现方式: 使用osgEarth::Util::RTTPicker 类进行鼠标拾取。 通过回调方法 onHit 和onMiss 处理拾取结果。 拾取到的特征信息会显示在 UI 控件上。cpp struct MyPickCallback : public RTTPicker::Callback { App& _app; MyPickCallback(App& app) : _app(app) {} void onHit(ObjectID id) { ...
