查询词典 sample method

The compressed point sample can be transferred progressively after serialization. Secondly, the thesis purposes another algorithm to render the compressed point data which can render the model without reconstructing the full structure of KD-Tree. The algorithm uses the View-Frustum Culling, Back-Face Culling and Level of Detail method, and boosts the speed and precision on rendering.

其次，提出了一个在此压缩算法上的模型快速绘制算法，该算法可以直接使用序列化后数据并不需要恢复完整的KD-树结构即可进行绘制，该算法使用了视锥裁减，背向面裁减，层次细节等方法，极大提高了绘制的速度和精度。
