图形和图像构建虚拟场景技术研究

阐述了图形和图像混合型构建虚拟场景的基本思想，对虚拟场景中的不同对象采用不同的处理方式，场景总体的全景视觉效果由基于图像的技术生成，主要利用了反映真实场景的高质量的图像，在无须复杂建模的情况下取得最真实的感官效果；对于场景中与用户交互部分则利用几何模型的方法来处理，对虚拟环境中用户要与之交互的对象进行几何模型构建，这样可以提高用户的沉浸感。对图形和图像建模型的两种不同方法进行了比较，研究了既提高场景真实感．又能加快渲染速度的混合建立场景的方法。

Research of Building Virtual Scenes Technology Based on Geometry and Image

In this paper the author clarifies the the basic idea of modeling based on geometry and image in virtual scenes. For the different objects in virtual scene using different treatment modalities, the overall panoramic scenes visual effects from image-based technology generation, the main advantage of reflecting the true scene of high-quality images, We have the most real sensory effects without the complexity of modeling; for the objects users to interact in a virtual environment dealing with geometry modelin...
