====== XRender ====== **//Inherited from//** [[class::qopenglwidget|QOpenGLWidget]],[[class::xview|XView]], **//Inherited by//** NULL **//Friend class//** NULL **//Description//** XRender类从XView继承，是用于三维视图的渲染和用户交互的视图基类，它支持多种渲染模式和显示状态，交互上它支持多种不同的对象选择和拾取方法，以及视图的操作（如旋转、平移、缩放），还支持云图渲染以及变形渲染，以及基于GLSL着色器语言的高级渲染技术。除此以外它还提供了用于指定裁剪平面和局部视图的方法接口以及定制功能专用数据的预览显示接口，可以根据需要显示多种标记。 为了提高渲染速度，XRender首先在帧缓冲区对象中渲染，然后通过纹理渲染到正常渲染上下文中。 XRender为三维场景提供了较完备的渲染以及交互方法，开发者可以从它继承很方便的定制更多专用三维场景的显示与交互。 **//Members//** * #ifndef [[xrender#use_qt4|USE_QT4]] * MainFrame *
