Modeling of scene animation is different from effect diagram modeling.
Each object needs to build a concrete three-dimensional model.
The scenario model is made according to the situation.
We can carry out model action in accordance with two standards.
During panorama view,and aerial view, because there are many models in the scene, system processing speed mainly determined by the total number of models used in the scene, you should try to use coarse mode.
Walk through in some specific buildings or entering the interior, due to the performance of the detail composition of the building,we should create a corresponding close fine mode.
Effect picture is shown in figure.4.
