基于拾取算法的产品交互式Web3D模拟的研究与实现

Research and implementation of a Web3D demonstration system based on the picking algorithm

产品的外观展示和全部功能的交互式模拟在电子商务领域具有很大的需求.Web3D计算机仿真系统在Web浏览器上运行,需要快速下载和运行,且以无需下载特定插件为佳.采用基于JAVA技术的Web3D引擎具有上述优势,可以实现产品的旋转、外观的缩放等基本展示功能.为了进一步提高产品功能的效率和改善交互模拟效果,在引擎实现了射线分层次求交拾取算法的基础上,最终实现产品包括交互功能在内的全面模拟.

E-commerce has great demand for 3D demonstration and fully interactive simulation of some products. To run the Web3D computer simulation system on the Web browser, it needs to be downloaded and run fast, without downloading special plug-ins. Applying open source Web3D engine based on JAVA has above-mentioned merits. The system can implement the interactive function such as rotation and zoom. To further increase the efficiency of the product function and improve the interactive simulation effect, the pricking algorithm for hierarchical intersection of rays is realized on the engine. Finally, a comprehensive simulation system including interactive function is achieved.
