Several groups developed in the last years augmented and virtual reality (AR/VR) software to visualize 3D molecules, most rather static, limited in content, and requiring software installs, some even requiring expensive hardware. We launched in 2020 moleculARweb (https://molecularweb.epfl.ch), a website that offers interactive content for chemistry and structural biology education through commodity web-based AR that works on consumer devices like smartphones, tablets and laptops. Among thousands of users, teachers increasingly request more biological macromolecules to be available, a demand that we cannot address individually. Therefore, to allow users to build their own material, we built a web interface where they can create online AR experiences in few steps starting from Protein Data Bank, AlphaFold or custom uploaded structures, or from virtual objects/scenes exported from the Visual Molecular Dynamics program, without any programming knowledge. The web tool also returns WebXR sessions for viewing and manipulating the models in WebXR-compatible devices including smartphones, tablets, and also immersive VR headsets with WebXR-capable browsers, where models can be manipulated even with bare hands when supported by the device. The tool is accessible for free at https://molecularweb.epfl.ch/pages/pdb2ar.html.
过去几年，有几个团队开发了增强现实（AR）和虚拟现实（VR）软件，以可视化 3D 分子，这些软件大多是静态的，内容有限，需要安装软件，有些甚至需要昂贵的硬件。我们在 2020 年推出了 moleculARweb（https://molecularweb.epfl.ch），这是一个网站，通过基于网络的、适用于智能手机、平板电脑和笔记本电脑等消费类设备的 AR 技术，提供化学和结构生物学教育的互动内容。在成千上万的用户中，教师越来越多地要求提供更多的生物大分子，我们无法逐个满足这一需求。因此，为了允许用户构建自己的材料，我们构建了一个网络界面，用户可以在该界面中使用 AlphaFold 或自定义上传的结构，或者从 Visual Molecular Dynamics 程序导出的虚拟对象/场景，在几步之内创建在线 AR 体验，无需任何编程知识。该网络工具还为在支持 WebXR 的设备中查看和操作模型提供 WebXR 会话，包括支持 WebXR 的智能手机、平板电脑，甚至沉浸式 VR 头显，在设备支持的情况下，甚至可以用裸手操作模型。该工具可在 https://molecularweb.epfl.ch/pages/pdb2ar.html 免费访问。
