摘要
针对驾驶虚拟现实系统中上坡道路的三维模型实现与平滑过渡的问题,基于Visual C++和OpenGL,提出一种修改方便的道路数据存储格式,分析一般地面与道路模型的设计方法。改进模型中平路与上坡连接处的过渡方法,并解决由此带来道路及两侧地块的建模与纹理贴图问题。给出改进前后道路模型的虚拟现实效果,结果表明,改进后上坡平滑过渡自然,有效地模拟实际路况。
Aiming at the problem of realizing and smooth transition of 3D uphill road model in driving virtual reality system, based on Visual C＋＋ and OpenGL, presents an easy modifying storage format of road data, and analyzes a design methed of usual terrain and road model. Improves the transition method of the connection between flat road and uphill, and solves the resulting problem of modeling and texture mapping of road and its both sides. Presents the virtual reality effect of road model, including no improved and improved. The result shows that the uphill road using improved model has smooth transition section,and it can efficiently simulate the details of the real uphill road.
