Title:
METHOD FOR CONTROLLING FRACTAL LEVEL OF THREE- DIMENSIONAL SEA SURFACE PICTURE BY COMPUTER GRAPHICS AND COMPUTER-READABLE RECORDING MEDIUM RECORDING PROGRAM FOR CONTROLLING FRACTAL LEVEL OF THREE- DIMENSIONAL SEA SURFACE PICTURE BY COMPUTER GRAPHICS
Document Type and Number:
Japanese Patent JP3035538
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To minimize a sense of visual incongruity caused by a shading processing different from the reality.
SOLUTION: Face sizes divided for every fractal level are calculated in accordance with a base face size which is to be original data of a three- dimensional sea surface picture in computer graphics. The upper limit value of face sizes which can generate a three-dimensional sea surface picture without a sense of incongruity is calculated in accordance with ratios of these calculated face sizes to the sea surface wavelength and the sea surface wave length, and display ranges of fractal levels of face sizes which exceed the calculates upper limit of face sizes are reduced.
