2. Outline Wat Makutkasattriyaram Background of the e-museum project Applied technologies for 3D creation Metadata and Web-based application Progress of the project Summary and future work2 3. Outline Wat Makutkasattriyaram Background of the e-museum project Applied technologies for 3D creation Metadata and Web-based application Progress of the project Summary and future work3 4. What is Wat Makutkasattriyaram?[wat-ma-kut-ka-sat-tri-ya-ram] temple Wat Makut is one of the royal temple in Bangkok, Thailand, completed in 1868.photo from http://www.dhammathai.org/4 5. Why we created an e-museumfor Wat Makut? Numerous murals and crafts related to the royal family and some historical events. 5 6. Outline Wat Makutkasattriyaram Background of the e-museum project Applied technologies for 3D creation Metadata and Web-based application Progress of the project Summary and future work6 7. Background of the e-museum project Began in July 2005 to celebrate the 50th birthday of Her Royal Highness Princess Maha Chakri Sirindhorn Her Royal Highness Princess Maha Chakri Sirindhorn7 8. Project Goals To preserve, manage, and publicize knowledge of Thai cultural heritage To create an online museum in parallel with a real museum To gain technical knowledge related to 3D object creation and visualization via the web8 9. e-Museum development components Wat Makut e-Museum ObjectMetadata and Web-based application Digitization Database Design construction 2D objects Web database (digital still photos) Application (LAMP) 3D objects Virtual museum9 10. Outline Wat Makutkasattriyaram Background of the e-museum project Applied technologies for 3D creation Metadata and Web-based application Progress of the project Summary and future work10 11. Applied technologies for 3D creation Technologies for creating 3D objects in thee-museum are:3D Laser Scanning Photographic VR (using 3D laser scanner) (using digital camera)11 12.
