3、re features to design the arcade naturalist city show platform. Keywords： Wuzhou Arcade Museum City， 3D Panorama， Multimedia Technology， Design Introduction With the popularity of Internet， the modern travelling ways leaded by network have entered into peoples lives. Released on September 14 by the
4、China Tourism Academy “Chinese Tourism E-commerce Development Report” shows that Chinese tourism e-commerce market scale reached 200 billion Yuan in 22010， nearly 15% of the total tourism revenue share. The current common digital travel ways are as follow： plane map， satellite images， aerial imagery
5、， and feature spot pictures. In recent years， the 2.5D map， 3D terrain， and virtual roaming gradually applied to the digital travel. These ways enhanced the vitality to the digital city， but their production cost is rather high. The 3D panoramic technology is widely used in tourist attractions， hote
6、ls， real estates and houses， leisure clubs， car shows， city building planning and other network virtual exhibitions. The application of 3D panoramic technology in attractions showcase mainly expressed by displaying the 3D panoramic showcase of tourist scenic spots and historical sites on internet to
7、 provide the tourist attractions with a chance to let the visitors keep a immersive image on them. The development of Wuzhou arcade naturalist city 3D panoramic multimedia presentation system can promote the construction of Wuzhou tourism information network， having extremely profound significance o
8、n improving the regional tourism information resources sharing， enhancing the quality of regional business， optimizing the travel information structure， and creating the network digital naturalist city， 3as well as raising the citys cultural taste. Wuzhou known as the “century trading port” was the
9、political， economic and cultural center of the Lingnan region， the arcade is the logo of its former bustling commerce. Building 3D panoramic display system of arcade naturalist city has a positive meaning on protecting and restoring the arcade culture. Multimedia Implementation Techniques Used in Ar
10、cade Naturalist City Analysis of 3D Panorama Technology Used in Arcade Naturalist City. Panorama usually means the image whose perspective is more than peoples normal viewing angle. While the panorama we mentioned hereinafter particularly refers to the image with 360 degrees horizontal viewing angle
11、 and 180 degrees vertical viewing angle. The users can choose their own perspective or zoom in and out at will through up and down or left and right rotation of mouse. Panorama is really just a graphic images mapped by some a geometric relationship about the surrounding scenes， only through the pano
12、rama players corrective treatment can make it become the three-dimensional panorama. The Commercial Port Authority in Wuzhou dismantled the ancient city walls to construct the streets. The original old 4neighbors houses were gradually replaced by the arcades， had built a stretching arcades group in
13、the old down at the east of the river. The finished 22 arcade streets included 560 legendary arcade building in harmony of Chinese and Western cultures， which was a collection of arcades with Chinese and foreign classical design. In the arcade streets， there were full of scholars and merchants， the
14、sum of the small or large stores reached more than 1，500 at their most prosperous period. Tens of thousands of wealthy businessmen were created there， with a reputation of “the thousand years key town of Lingnan city， the century commercial port of Guangdong and Guangxi“. From Wuzhou arcade appearan
15、ce， lots of very typical Chinese architectural style at that time can be found. The streetscape of arcade naturalist city suited the panoramic technology application， can realize the panoramic technology show through dividing the region by streets. The Technical Characteristics of the 3D Panorama Us
16、ed in Arcade Naturalist City. The object panorama is aimed at the e-commerce on Internet， its main difference from scenic panorama is that when shooting the targeting object， rotated the object rather than camera， each rotation of a angle shooting a sequence. When it was complete， it usually need sh
17、oot 12-15 5images. Then edited and generated an image through 3D panoramic software after the PS processing， embed them in your web pages and finally published to your website. The object panorama also has a very wide range of application： merchandise and toys display， heritage appreciation， arts an
18、d crafts show， etc. The Panoramic Virtual Reality Technology Is More Suitable for Using in Arcade Naturalist City. Regarding the architectural features of Wuzhou arcade naturalist city， it is with the Chinese architectural style， like ressette， tile carving， and memorial arch and so on. Analyzed fro
19、m the long development cycle and high production cost， the 3D model of virtual reality is in a disadvantageous position to show these details. To honestly reflect the building real， using three-dimensional panoramic virtual reality is more appropriate， with digitized reproduction of the real scene r
20、eal scene and strongly realistic. Showing Design and Interactive Experience. Refer to the showing design means， sound， painting， video and other multimedia technologies can be fully made use of to recover the scene. Using virtual reality and other modern display technologies to reproduce scenic spot
21、s and historical background and strengthen the arts and appealing， can display 6the phantom photographed scene effect， to bring the audiences with an immersive feel. The ideal virtual environment can produce realistic effects to restore history， even more artistically appealing than the real scene.
22、Allow users more interactive operation to increase the sense of on-site experience. Basic Practical Methods of Multimedia Showcase Design of Wuzhou Arcade Naturalist City To build a tourism and leisure base and a famous suitable for living Lingnan landscape city with thriving trade and tourism， and
23、as well as the tourist hub of the eastern region of Guangxi， an information service platform should be established. Panoramic Shot. The used equipments included： camera， fisheye， tripod head and other equipment combination. The 360-degree scenes only need to take two or three photos， and need to hav
24、e the professional panoramic collage software to synthesize pictures together and panorama released. Attentions should be paid when shooting as follows： 1. Try to use the same set of shooting parameters. Used the cameras photometry to test the aperture and shutter， and then turned to M mode， setting
25、 the aperture and shutter data into 7this parameter. 2. The attentions paid when shooting， taking the body as centre to spinning shot， between two photos must leave a certain overlapped place and this place tried to be not less than 1 / 4 of the whole screen. My general proportion of overlapped scre
26、en is between 1/2-1/3， which can effectively improve the accuracy after post-processing. To reduce the deformation of the wide - angle edge can impact on the screen. 3. When shooting， you can shoot in horizontal way or vertical way. I preferred to vertical way， as it can greatly improve the vertical
27、 height of the final photos. Image Post-processing. When post-processing the film materials， usually used Pano2VR， PTGui Pro， Photoshop and other software to make treatments like stitching， color correction， spill removal and so on. Build a three-dimensional panoramic round viewing through panoramic
28、 image trimming as well as the color corrections in the picture， can make up of several scattered pictures into a large-format complete picture， and then output the panoramic images after seamless joint of images. Multimedia Showcase Platform Design. The showcase design in the dress of multimedia te
29、chnology can be the abstract time， 8also be some kind of state of existence from psychological and spatial experience. In addition to the feature of timing and interactivity， the display design needs to have aesthetic characteristics compounded by other types as well. The advertising design， archite
30、ctural design， multimedia design， online media design， and interactive game design can be comprehensively used together to form a higher level cultural demands. The Art Optimization Design of Wuzhou Arcade Naturalist City Multimedia Display Interface After having the arcade naturalist city roaming s
31、ystem based on virtual panoramic technology， the further optimization design is needed for its interface to achieve the distinctive features， strong interactivity， prominent dynamic sense and other art features. In the design of the interface， the architectural features and designs of the Lingnan re
32、gion should be highlighted， meanwhile in the design of the background music， the Lingnan style of music also should be especially selected out， to blend the Lingnan culture favors into the roaming system interface style， and bring the surfers with the special experience of Lingnan culture when brows
33、ing the arcade naturalist city multimedia system. Then， adding 9some dynamic flash and audio applications into webpage design， so that when the viewers click on scenic spots， accompanied with dynamic viewing effect， to achieve the perfect unity of the visual， auditory， and interactive， and enhance t
34、he immersive feel of the viewer. Summary and Prospects Multimedia technology is widely used in kinds of exhibitions， which will better reflect the artists design talent. All of this will make the boundaries among artistic creation， everyday life and applied art， and commercial activities become very
35、 fuzzy. The multimedia presentation ways are diverse， can support video reproduction， sound effects， map navigation， hot virtual roaming， animation and other connections， can also be linked with the three-dimensional geographic system， to display in the integrated software.
