Document Type and Number:
Japanese Patent JP5524146
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a perspective drawing creation system, a perspective drawing creation program and a perspective drawing creation method for quickly creating and displaying a perspective drawing given appropriate gradation.SOLUTION: The perspective drawing creation system includes: a data acquisition part for acquiring three-dimensional data and texture data; a site definition part for defining the site of a building in the three-dimensional data; a shadow generation part for extracting a surface object forming the outer wall surface of the building and a shadow generation object for generating a shadow in the surface object from the three-dimensional data, and for generating a shadow by the shadow generation object on the basis of a visual point and a light source; a shadow filter generation part for generating a shadow filter giving gradation to the generated shadow; a surface filter generation part for generating a surface filter giving gradation to the surface object; and an image synthesizing part for overlapping the shadow, the shadow filter and the surface filter on the surface object.
