For the question of fusing display of circular area on 3d model, a simple solution was put out, that used a spot light source to simulate the fusing effect of circular area display on 3d model.

针对虚拟仿真应用程序开发中的二维圆形区域与三维实体模型的融合显示问题，提出了一种简便的解决方案，即用聚光光源产生的光斑来模拟二维圆形区域在三维目标模型上的影印效果。

That opens up the possibility of putting virtual objects into the real world, letting you "pick up" a computer-generated 3D architectural model and spin it around in your hand, for instance, or gesture to control a virtual display appearing on an actual wall.
