Abstract
A rendering system and method, and a recording medium therefor are provided. The rendering system imports geometry and hierarchy structure information on a three-dimensional (3D) computer-aided design (CAD) model, which is produced in a commercial 3D CAD system, from the 3D CAD system through an interface, performs scene editing necessary for rendering without changing the initially modeled data, and then performs rendering. Accordingly, it is not necessary to correct the geometry data and restore the hierarchy structure information, and rendering can be easily performed in a short time.
Claims14
A rendering system comprising:
- a computer-aided design (CAD) interface which accesses a CAD system, directly imports CAD data produced in the CAD system, divides the CAD data into geometry data of a product and related data on other aspects, and converts the divided data;
- a database which stores the geometry data and the related data that has been divided and converted by the CAD interface;
- a scene editing module which edits a scene based on the geometry data using the related data;
- and
- a renderer which performs rendering on the scene that has been edited by the scene editing module.
A rendering method comprising:
- interfacing which includes accessing a computer-aided design (CAD) system, importing CAD data from the CAD system, dividing the CAD data into geometry data of a product and related data on other aspects to be suitable to a structure of a database of a rendering system, and converting the divided data;
- editing a scene based on the geometry data using the related data stored in the database;
- and
- rendering the scene that has been edited.
A rendering method comprising:
- accessing a computer-aided design (CAD) system, importing CAD data from the CAD system, dividing the CAD data into geometry data of a product and related data on other aspects to be suitable to a structure of a database of a rendering system, and converting the divided data;
- editing a scene based on the geometry data using the related data stored in the database;
- determining whether a modification to the edited scene is requested;
- if it is determined that the modification is requested, selecting a unit of data to be imported and importing modified geometry data in the selected unit;
- comparing an imported part identification with a previously stored part identification;
- and
- if the imported part identification and the previously stored part identification are the same, replacing existing geometry data corresponding to the part identification with the imported geometry data.
A rendering method comprising:
- accessing a computer-aided design (CAD) system, importing CAD data from the CAD system, dividing the CAD data into geometry data of a product and related data on other aspects to be suitable to a structure of a database of a rendering system, and converting the divided data;
- editing a scene based on the geometry data using the related data stored in the database;
- and
- storing scene editing information, which is environment information necessary for scene editing among the related data, as a separate file.
A database of a rendering system, comprising:
- geometry data which is geometrical information on each three-dimensional geometry;
- geometry hierarchy structure data on the hierarchy structure in geometries indicated by the geometry data;
- rendering information which is related data necessary for rendering;
- and
- scene editing information which is environment-related information necessary for scene editing.
