Abstract: An abstract pattern plate-making system removes an undesired pattern from an endless pattern in the process for making a plate for printing abstract patterns on architectural materials. For this purpose, it has a scramble processing part 10 and a pixel copy processing part 11.The scramble processing part 10 divides endless pattern data into blocks and repeats processing in which pattern data in two blocks selected at random from among the divided blocks are combined together by a composition technique using mask data having a predetermined pattern, thereby removing an undesired pattern. The mask pattern size may be either smaller or larger than the block size. The mask pattern may be a multi-valued pattern. Further, when the endless pattern is divided into blocks, the blocks may be allotted so as to be a little offset from the endless pattern.

Abstract: On a surface of a decorative paper, vessel perforation of natural wood is reproduced by an offset groove (100) consisting of three steps of embossing grooves (110, 120, 130) of the nesting structure. Respective grooves are such that they are deeper according as positions thereof shift to the internal, and are disposed in a manner to be eccentric in a length direction. Within the groove, a convex bank portion (140) in which the bottom surface is linearly protruded is formed. An embossing plate for processing such an offset groove is prepared on the basis of a vessel cross section pattern inputted by using natural wood. The inputted plane vessel cross section pattern is replaced by an approximate elliptical figure. A three-dimensional virtual vessel perforation model is determined by calculation using the elliptical figure. Equi-depth lines for set predetermined depths are extracted from the three-dimensional model and contour figures of embossing grooves (110, 120, 130) are obtained.

Abstract: A method and system for making a baby-plate for use in printing abstract patterns on architectural materials wherein glitches are easily confirmed and removed. A unit material is read by an input scanner (1) and the image digitized into pixels of given density. The image data of the unit material is dissolve-composited repetitively M times vertically (M being a positive integer) and N times horizontally (N being a positive integer) in an endless processor (9) to construct pattern data of given size. Some pixels are culled from the pattern data by a glitch-checking processor (10) for creating reduced pattern data for display on the screen of a monitor (14) for determining the presence of an undesired pattern, i.e., a glitch, by viewing the screen of monitor (14). If there is a glitch, then the glitch is removed by a glitch removal processor (11).

Abstract: A computer graphic image generating apparatus for generating an image based on a computer graphic model including shape information, camera information, camera position information, object position information, texture information, light source information and mapping information which includes texture image information. The apparatus includes a storage device, or memory, and means for calculating the amount of space in the storage device required to store all the information used to generate an image. The apparatus also includes means for storing the information for an image in the storage device without wasting any storage space. The apparatus also includes means for converting image information created for a first image generating system having a first shading calculation system into image information usable on a second image generating system having a different shading calculation system.
