摘　　要：虚拟室内漫游技术已成为房地产销售的重要手段,长期以来3DS室内效果图得到广泛应用,但基于3DS室内模型的虚拟室内漫游技术鲜有研究。以3DS MAX、VC++和OpenGL软件为平台,对基于3DS室内模型虚拟漫游的几个关键技术进行研究。室内场景建模完全在3DS MAX软件下实现,为实现场景管理对墙体、地面和顶模型进行规划处理,用多边形建模法实现;室内场景管理则基于Portal技术,设计视锥体裁剪算法,实现了实时性漫游;室内漫游采用包围球碰撞检测技术,实现了真实感漫游。Virtual indoor wandering technology became an important means of real estate sales,for a long time 3DS indoor effect diagram were widely used,but there were few studies about virtual indoor wandering technology based on the 3DS model.With 3DS MAX,VC＋＋and OpenGL software platforms,several key technologies of the virtual indoor wandering based on 3DS model were studied.Indoor scene model is entirely achieved with 3DS MAX,in order to achieve the scene management,the walls,floor and ceiling models are created by polygon modeling.Indoor scene management is based on the portal technology,the cone cutting algorithm is designed to realize the real-time wandering.The bounding sphere collision detection technique is used to achieve the realistic.
