RENDERING APPARATUS FOR CYLINDRICAL OBJECT AND RENDERING METHOD THEREFOR
First Claim
1. A rendering apparatus for performing rendering of cylindrical objects, comprising:
- a data input unit image transmitting rendering data of individuals of the cylindrical objects which are classified by thickness when three dimensional model data of the cylindrical objects is input;
a first rendering unit for performing an alpha line rendering for thin individuals of the cylindrical objects which are classified by thickness;
a second rendering unit for performing a ribbon triangulation rendering for thick individuals of the cylindrical objects which are classified by thickness;
a storage for integrating first rendering result data transmitted from the first rendering unit with second rendering result data transmitted from the second rendering unit to transmit final rendering result data; and
a rendering output unit for outputting the final rendering result data.

Abstract
A rendering apparatus for performing rendering of cylindrical objects includes: a data input unit image transmitting rendering data of individuals of the cylindrical objects which are classified by thickness when three dimensional model data of the cylindrical objects is input; a first rendering unit for performing an alpha line rendering for thin individuals of the cylindrical objects which are classified by thickness; and a second rendering unit for performing a ribbon triangulation rendering for thick individuals of the cylindrical objects which are classified by thickness. Further, the rendering apparatus includes a storage for integrating first rendering result data transmitted from the first rendering unit with second rendering result data transmitted from the second rendering unit to transmit final rendering result data; and a rendering output unit for outputting the final rendering result data.
