this is a report of course efforts in exploring and visualizing shapes made by movements. A pedagogical attempt was made to visualize forms made by transition. the forms were made by 3D scans of body movements in play...

＜正＞For the rational mode of intervention of the traditional arts’ protection and promotion from cad technology,the paper researches on the computer-aideddesign technology of paper-cut art *** on the protection of artists’ creative thinking,creativity and production in designing process are divided effectively. the inefficient repeating and uncreative works in paper-cut art are completed by using cad technology. Artists’ creative thinking are fleetly expressed with lots of schemas and works’production is aided perfectly. Based on digital cad technology theory,paper-cut element symbols database are ***-cut cad system based on CorelDraw is implemented by using the technology of plane array parameterization, path decoration,folding and combination of lots of *** designing process validation is carried through with typical traditional designs.

Experimental results show the proposed watermarking scheme is almost completely robust to rotate,scale, transplant (RST) as well as their combinations,and also strong enough to cropping attacks.
