The number of polygons comprising interesting architectural models is many more than can be rendered at interactive frame rates. However, due to occlusion by opaque surfaces (e.g., walls), only a small fraction of a typical model is visible from most viewpoints.We describe a method of visibility preprocessing that is efficient and effective for axis-aligned or axial architectural models. A model is subdivided into rectangular cells whose boundaries coincide with major opaque surfaces. Non… CONTINUE READING
