We report the availability of a digitized Chinese male and a digitzed Chinese female typical of the population and with no obvious abnormalities. The embalming and milling procedures incorporate three technical improvements over earlier digitized cadavers. Vascular perfusion with coloured gelatin was performed to facilitate blood vessel identification. Embalmed cadavers were embedded in gelatin and cryosectioned whole so as to avoid section loss resulting from cutting the body into smaller pieces. Milling performed at -25 degrees C prevented small structures (e.g. teeth, concha nasalis and articular cartilage) from falling off from the milling surface. The male image set (.tiff images each of 36 Mb) has a section resolution of 3072 x 2048 pixels ( approximately 170 micro m, the accompanying magnetic resonance imaging and computer tomography data have a resolution of 512 x 512, i.e. approximately 440 micro m). The Chinese Visible Human male and female datasets are available at http://www.chinesevisiblehuman.com. (The male is 90.65 Gb and female 131.04 Gb). MPEG videos of direct records of real-time volume rendering are at: http://www.cse.cuhk.edu.hk/~crc

The United States Visible Human Project (VHP) created a digital image data set of complete human male (data acquisition finished in November 1994) and female (data acquisition finished in December 1995) cadavers in magnetic resonance imaging (MRI), computed tomography (CT), and anatomical (anatomic serial section) modes. VHP aroused worldwide enthusiasm for Visible Human Research (VHR), and the data set is being used in a variety of research and educational domains. The Visible Korean Human (VKH) male was produced in March 2001. To accelerate worldwide VHR and to promote virtual anatomy as a revolutionary break with conventional anatomy, more visible human data sets representative of different populations of the world are in demand. The Chinese Visible Human (CVH) male (created in October 2002) and female (created in February 2003) project achieved greater integrity of images, easier blood vessel identification, and were free of organic lesion (unlike the other visible human projects). We performed data acquisition, three-dimensional (3D) reconstruction, and visualization with improved technology to create CVH male and female. CVH is the first volumetric data representing a complete normal adult human male and female of an Asian population. This article presents the history of Chinese Visible Human cadavers and the methods and technology used to produce the data set.

In view of the low accuracy of the current digital leather experience design method, this paper uses virtual reality technology to study the depth of digital leather experience design. First of all, according to the influence characteristics of digital leather experience effect, the evaluation indicators are selected from the aspects of digital leather experience design and leather quality, design efficiency and experience effect, and the evaluation index system of digital leather experience design is established, and the entropy right of the evaluation index of digital leather experience effect is defined through the judgment matrix. Then, virtual reality technology is used to analyze the reliability of digital leather experience design, design the model architecture of digital leather experience design, effectively improve the stability of digital leather experience design information transmission, and complete the digital leather experience design. The simulation experiment results show that the proposed algorithm has certain virtual reality value, which can effectively reduce the efficiency of digital leather goods experience design and improve the accuracy of digital leather goods experience design.

This research use a reasonable mix of materials and the structures to achieve highly shading performance of curtain fabrics. Choosing jacquard double layers structure and black passee as layer parallel with ratio of 2:1:1. Meanwhile, the thesis puts forward a pattern of the shading curtain fabrics. It has two series of color, the spring & the summer color and the autumn & winter color. To show the matching effect of the curtains, photos of indoor simulation by 3DMAX has made. Then the pattern samples were woven. Shading performance of samples were tested and analyzed. Finally a product simulation curtains were produced. Through the test of fabric shading, the shading rate is over 98%, which proves that they have good shading performance. And the average shading rate is over 99.4% which meet the full shading standard.
