摘要

摘要: 花卉植物高真实感的仿真交互是目前虚拟植物可视化研究的一个重要方向。随着虚拟现实技术的普及，越来越多的应用采用了VR头戴设备的呈现方式。VR系统需要高度真实的沉浸感画面，通用的植物建模和图形引擎渲染功能已不能满足该需求。该文通过分析光照原理并融合基于物理的渲染技术，提出基于双向散射分布函数BSDF的花卉植物高度真实感的物理渲染算法，利用ShaderLab，对几种盆栽花卉植物在光照下进行仿真，并对融合算法做优化处理。针对VR头盔设备HTC Vive的成像效果，对图像进行扭曲变形优化，使画面更符合人眼双目立体视觉成像效果，增强系统沉浸感。最后基于该方法设计并实现了一个头盔式VR花卉植物仿真模拟系统，获得了逼真的场景漫游体验效果。

Abstract: The high realism simulation interaction of flower plants is an important direction of virtual plant visualization. More and more applications are presented by the Virtual Reality (VR) headset device with the popularity of virtual reality technology. The VR system requires a highly realistic immersive picture for which generic plant modeling and graphics engine rendering capabilities are no longer sufficient. In this paper, a physical rendering algorithm is proposed based on Bidirectional Scattering Distribution Function (BSDF) to realistic flower plants by analyzing the principle of illumination and combining the Physics-Based Shading (PBS) technology. Potted flora in light mode is simulated by ShaderLab and the fusion algorithm is optimized. The image is distorted by lens matching rendering technology to make the virtual scene closer to the real human eye vision and reduce the user vertigo when user wearing the VR headset when using the VR helmet equipment HTC Vive. Finally a helmet VR floral plant simulation system is designed and a realistic immersive scene is realized.
