GRAPHIC SYSTEM, DASHED LINE TEXTURE IMAGE GENERATION DEVICE AND DASHED LINE TEXTURE IMAGE GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To simplify the generation and management of a dashed line texture image, and to reduce performance deterioration due to overhead in the case of attaching a dashed line texture image.;SOLUTION: This graphic system is provided with: a texture storage region 4b in which a dashed line texture image wherein modification function-categorized dashed line patterns are arranged is stored; a texture module 3b for reading the specific dashed line patterns arranged in the dashed line texture image based on coordinates on the dashed line texture image; and a plotting module 3c for plotting the dashed lines by using the dashed line patterns read by the texture module 3b; or the like.;COPYRIGHT: (C)2008,JPO&INPIT
