基于OpenGL的三维图形真实感技术研究

Technology Research On Realistic Image Of 3-D Graph Based on OpenGL

本文在分析和研究OpenGL下实现三维真实感效果处理技术的基础上,通过读取STL文件数据,在场景中绘制三维物体模型,定义了光照模型、材质属性、视口大小、投影方式和纹理映射,从而实现了三维图形的真实感显示,并具有改变光照条件,设置渲染模式等功能。

Based on realizing three dimensional effects through OpenGL,this paper attempts to read data of STL,draw 3D models on scene and define illumination model,material properties,view port size,projection mode and texture mapping;thus 3D graphics can be vividly presented and functions like changing illumination conditions and setting rendering model can be realized。
