基于OpenGL的球体生成算法可视化仿真研究

Research on Simulation of Sphere Generation Algorithm Based on OpenGL

研究计算机图像的三维可视化优化问题,针对图像生成慢的缺点,为了仿真计算机图形学中三维球体的生成过程,提高图像生成速度,提出了一种三角形分割的算法,实现了球体生成算法可视化的仿真系统CAI。系统的实现,摒弃了原来可视化系统中依靠计算最佳逼近"像素点"的位置来显示图形的方法,而是用三角形面代替原来的"像素点",对其进行一系列的分割以实现最终效果。实验结果表明,方法可以实现三维图形生成算法可视化仿真效果,突破了原来只能实现二维图形的局限性,而且生成图形的速度较快,具有很好的逼真度。

In order to simulate generating processof three-dimensional sphere,this paper proposed a method of triangle splitting which can achieve a visual simulation system CAI of 3D spheres.For the implementation of the system,we use triangles instead of ＂pixels＂ to carry out the segmentation of triangles in order to achieve the ultimate effects,replacing the method of calculating the best approximation ＂pixel＂ position to display graphic in original system.The result shows that this method can actualize the generation process of 3D-graphic and break the limitations of the two-dimensional graphics.It is very realistic and fast.
