Abstract
The method and system for generating texture of a target object acquire first information about a surface geometry and second information about a constituent material of the target object, and third information about a kind of incident light falling on a surface of the target object, preferably, from respective databases, calculates a intensity distribution of scattered light on the target object and in an area surrounding the target object using Maxwell's equations based on the first, the second and the third information, and calculates a two-dimensional intensity distribution of the scattered light at a specified angle to the surface of the target object as generated texture of the target object using the thus calculated intensity distribution of the scattered light.

A texture generating system that generates texture of a target object, comprising:
- a database section comprising a first database in which first information about plural surface geometries of objects is registered, a second database in which second information about plural constituent materials of the objects is registered and a third database in which third information about plural kinds of incident light falling on a surface of a object is registered;
- a display section for displaying said first information about said plural surface geometries of the objects, said second information about said plural constituent materials of the objects and said third information about said plural kinds of the incident light, which are registered in said first database, said second database and said third database of said database section, respectively, as well as the texture of the object;
- selection input means for selecting said first information about a surface geometry corresponding to said target object from said first information about said plural surface geometries of the objects displayed on said display section, said second information about a constituent material of said target object from said second information about said plural constituent materials of the objects displayed on said display section and said third information about a kind of the incident light from said third information about said plural kinds of the incident light displayed on said display section;
- and
- a computing section for calculating, based on said first information about said surface geometry of said target object, said second information about said constituent material of said target object and said third information about said kind of the incident light which are selected by said selection input means and read out from said database section, a intensity distribution of scattered light on said target object and in an area surrounding said target object using Maxwell's equations as well as calculating a two-dimensional intensity distribution of said scattered light at a specified angle to an surface of said target object as generated texture of said target object using the thus calculated intensity distribution of said scattered light,
- wherein said two-dimensional intensity distribution of said scattered light calculated by said computing section is displayed on said display section as said generated texture of said target object.
