虚拟现实的应用正变得越来越成熟。这种系统的要求和复杂性正在稳步增加。为了专注于应用中的交互可能性，现实的和详细的环境往往被省略。创建一个准确和现实的虚拟环境不是外行人的任务，而是3D设计和建模专家的任务。为了节约成本和避免雇佣专家，全景图像经常被用来创建看起来很真实的虚拟环境。这些图像可以由非专业人员捕捉和提供。全景图像在许多情况下是手工制作的三维模型的替代物，因为它们提供了沉浸感，而且只需按下一个按钮就可以捕捉到一个场景的细节。这项工作研究了在某些情况下，是否应该用手工重新制作一个环境的细节，或者是否建议使用全景图像来制作虚拟环境。为此，我们创建了一个交互式的虚拟环境，其中手工制作的3D环境与用全景图像创建的环境几乎没有区别。加入了互动元素，并进行了用户研究，以调查两种环境对用户的影响。所进行的研究表明，全景图像可以成为3D建模环境的有效替代品。
原文标题：Investigating the Sense of Presence Between Handcrafted and Panorama Based Virtual Environments
原文：
Virtual Reality applications are becoming increasingly mature. The requirements and complexity of such systems is steadily increasing. Realistic and detailed environments are often omitted in order to concentrate on the interaction possibilities within the application. Creating an accurate and realistic virtual environment is not a task for laypeople, but for experts in 3D design and modeling. To save costs and avoid hiring experts, panorama images are often used to create realistic looking virtual environments. These images can be captured and provided by non-experts. Panorama images are an alternative to handcrafted 3D models in many cases because they offer immersion and a scene can be captured in great detail with the touch of a button. This work investigates whether it is advisable to recreate an environment in detail by hand or whether it is recommended to use panorama images for virtual environments in certain scenarios. For this purpose, an interactive virtual environment was created in which a handmade 3D environment is almost indistinguishable from an environment created with panorama images. Interactive elements were added and a user study was conducted to investigate the effect of both environments to the user. The study conducted indicates that panorama images can be a useful substitute for 3D modeled environments.
