摘　　要：针对传统室内软装三维模拟系统选取几何建模方法三维模拟室内软装效果,缺乏有效的充实和渲染手段,真实性差。文中设计一种基于OpenGL与Direct3D的室内软装三维模拟系统,采用3DMAX软件建立室内模型,将该模型导入OpenGL三维图形标准库模块中,利用基本几何图元绘制室内软装场景元素,通过穿墙、重叠以及尺寸约束函数对场景元素进行约束,确保室内软装代理区域合理布局,充实室内模型,充实后室内模型传送至Direct3D渲染引擎模块变换单元实施软装布局,利用照明单元和光栅化单元对布局后室内进行渲染,获取最优室内软装效果,并输出室内软装三维模拟图像。实验结果表明,利用该系统三维模拟的室内软装真实性强,编辑操作平均运行时间为327 ms,用户满意度高。The traditional three-dimensional simulation system for indoor soft-fitting chooses geometric modeling method to simulate the effect of indoor soft-fitting,which lacks effective enrichment and rendering means,and has poor authenticity. Therefore,an indoor soft-fitting 3D simulation system based on OpenGL and Direct3D is designed. The indoor model is built by means of 3DMAX software. The model is imported into OpenGL 3D graphics standard library module. The elements of indoor soft-fitting scene are drawn by using basic geometric primitives. The elements of indoor soft-fitting scene are constrained by piercing walls,overlapping and size constraint functions,so as to ensure the reasonable layout of the agent area of indoor soft-fitting. The enriched indoor model is transmitted to the transformation unit of Direct3D rendering engine module to implement soft-fitting layout. The lighting unit and rasterization unit are utilized to render the arranged room,so as to obtain the optimal indoor soft-fitting effect and output the three-dimensional simulation image of the indoor soft-fitting. The experimental results show that the indoor soft-fitting simulation using this system has strong authenticity,the average running time of editing operation is 327 ms,and the user satisfaction is high.
