Description

一种基于公有云的三维图形数据共享方法及云管理平台
本申请要求于2021年12月16日提交中国专利局、申请号为202111541629.3、申请名称为“基于云技术的图形数据库服务提供方法及云管理平台”的中国专利申请的优先权，和要求于2022年03月25日提交中国专利局、申请号为202210302425.2、申请名称为“一种基于公有云的三维图形数据共享方法及云管理平台”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及云技术领域，尤其涉及一种基于公有云的三维图形数据共享方法及云管理平台。
背景技术
随着计算机行业的迅速发展，用户在终端设备上所能浏览的内容变得更加丰富和有趣。例如，某个终端设备可播放包含三维(3-dimension，3D)场景的图像、视频和游戏等内容，从而为用户提供优质的观看体验。
目前，三维图形文件可用于呈现三维场景，三维图形文件包含了已经渲染好的三维场景的图形数据(也可以称为三维图形数据)，例如，已渲染的某个建筑空间的数据等等。那么，终端设备下载三维图形文件后，可基于三维图形文件呈现出相应的三维场景，以提供给用户观看和体验。
由于三维图形文件通常是提前预置且固定的，用户往往只能批量下载三维图形文件，并按这些文件的指示来呈现出相应的三维场景。可见，用户无法按照自身的需求，来灵活查询和获取某个三维场景的图形数据，从而呈现出用户自身所需观看的三维场景。
发明内容
本申请实施例提供了一种基于公有云的三维图形数据共享方法及云管理平台，云管理平台可满足图形数据使用者对特定三维图形数据的下载需求，向图形数据使用者提供其所需的三维图形数据，以充分服务图形数据使用者的业务。
本申请实施例的第一方面提供了一种基于公有云的三维图形数据共享方法，该方法包括：
当N个图形数据提供者想上传三维图形数据时，云管理平台可向N个图形数据提供者提供三维图形数据上传接口(例如，三维图形数据上传接口可以为云管理平台所提供的上传界面)，以通过三维图形数据上传接口获取N个图形数据提供者输入的N个三维图形数据和N个三维图形数据的属性信息，其中，N个三维图形数据为已经渲染好的N个三维图形文件，N为大于1的正整数。
获取N个三维图形数据和N个三维图形数据的属性信息后，云管理平台还可面向N个图形数据提供者，提供N个三维图形数据的介绍页面，该介绍页面显示N个三维图形数据的介绍信息，N个介绍信息包括N个三维图形数据的属性信息，这N个介绍信息可共图形数据使用者浏览，以供图形数据使用者选择所需的三维图形数据。
云管理平台还可向图形数据使用者提供数据确定接口(数据确定接口可以为介绍页面中 的数据查询输入栏)，以通过数据确定接口确定图形数据使用者从N个三维图形数据中选择满足自身需求的目标三维图形数据，并将目标三维图形数据提供给图形数据使用者。那么，数据使用者可基于目标三维图形数据，呈现出自身所需的三维场景。例如，元宇宙中，模拟某个现实建筑物的虚拟空间。
从上述方法可以看出：当N个图形数据提供者想上传三维图形数据时，云管理平台可提供上传接口，以通过上传接口接收来自N个图形数据提供者的N个三维图形数据和N个三维图形数据的属性信息。接着，云管理平台可向图形数据使用者提供N个三维图形数据的介绍页面，该介绍页面用于显示N个三维图形数据的介绍信息，N个介绍信息包括N个三维图形数据的属性信息。当图形数据使用者想下载N个三维图形数据中的目标三维图形数据时，可通过云管理平台提供的数据确定接口通知云管理平台，以使得云管理平台将目标三维图形数据提供给图形数据使用者，使得图形数据使用者可基于目标三维图形数据呈现出相应的三维场景。由此可见，云管理平台可采集不同图形数据提供者自由上传的各个三维图形数据。当图形数据使用者需要其中某个三维图形数据时，云管理平台可满足图形数据使用者对特定三维图形数据的下载需求，向图形数据使用者提供其所需的三维图形数据，以充分服务图形数据使用者的业务。
在一种可能的实现方式中，该方法还包括：云管理平台提供登录接口，登录接口用于分别接收N个图形数据提供者输入的账号和密码，其中，N个图形数据提供者输入的账号和密码已在云管理平台注册，云管理平台在对N个图形数据库提供者的账号和密码进行鉴权成功后，允许N个图形数据库提供者访问三维图形数据上传接口；登录接口还用于接收图形数据使用者输入的图形数据库使用者的账号和密码，其中图形数据库使用者的账号和密码已在云管理平台注册，云管理平台在对图形数据库使用者的账号和密码进行鉴权成功后，允许图形数据库使用者访问数据确定接口。前述实现方式中，当N个图形数据提供者想上传三维图形数据时，云管理平台可向N个数据提供者提供登陆接口(例如，登录接口可以为云管理平台所提供的面向N个图形数据提供者的登录界面)，以通过登陆接口对N个数据提供者的帐号和密码进行鉴权。在对N个图形数据提供者的鉴权成功后，云管理平台允许N个图形数据提供者登录云管理平台，并向N个图形数据提供者提供上传接口。当图形数据使用者想下载目标三维图形数据时，云管理平台可向图形数据使用者提供登录接口(例如，登录接口可以为云管理平台所提供的面向图形数据使用者的登录界面)，以通过登录接口对图形数据使用者的帐号和密码进行鉴权。在对图形数据使用者的鉴权成功后，云管理平台允许图形数据使用者登录云管理平台，并向图形数据使用者提供N个三维图形数据的介绍页面以及数据确定接口。
在一种可能的实现方式中，云管理平台提供数据确定接口之前，三维图形数据上传接口还用于获取图形数据提供者发送的三维图形数据更新请求，该方法还包括：云管理平台基于三维图形数据更新请求，对目标三维图形数据进行更新，得到更新后的三维图形数据，更新包含以下至少一项：针对目标三维图形数据进行数据增加、数据删除和数据修改；则云管理平台将目标三维图形数据提供给图形数据使用者，包括：云管理平台将更新后的三维图形数据提供给图形数据使用者。前述实现方式中，当图形数据提供者需要更新目标三维图形数据时，可通过上传接口向云管理平台发送针对目标三维图形数据的数据更新请求。云管理平台得到数据更新请求后，可基于该请求对数据库中的三维场景的图形数据进行更新操作， 得到更新后的三维图形数据，更新操作具体为数据增加、数据删除和数据修改中的至少一种。由此可见，图形数据提供者还可对云管理平台提供的数据库中的三维图形数据进行更新，如此一来，不同数据提供者可协同合作，在数据库中原有的三维图形数据的基础上进行增加、删除和修改等操作，得到新的三维图形数据，从而提高了三维场景构建的便捷性，且能减少开发成本。
在一种可能的实现方式中，数据确定接口具体用于获取图形数据使用者发送的数据查询请求，数据查询请求用于指示图形数据使用者所需的三维图形数据的需求信息，云管理平台从N个属性信息中查找符合需求信息的目标属性信息，将目标属性信息对应的三维图形数据确定为目标三维图形数据。前述实现方式中，由于N个三维图形数据的属性信息可作为N个三维图形数据的索引，若有某个三维图形数据的属性信息(即某个三维图形数据的索引)符合数据查询请求所指示的需求信息(即图形数据使用者针对其所需的三维图形数据所指定的索引范围)，则将该三维图形数据准确地确定为目标三维图形数据。
在一种可能的实现方式中，三维图形数据上传接口还用于获取N个图形数据提供者输入的N个三维图形数据的定价信息，介绍页面还用于显示N个三维图形数据的定价信息，云管理平台将目标三维图形数据提供给图形数据使用者，包括：云管理平台提供付费接口，付费接口用于获取图形数据使用者针对目标三维图像数据的付款；云管理平台在确认图形数据使用者针对目标三维图像数据的付款成功的前提下将目标三维图形数据提供给图形数据使用者。前述实现方式中，云管理平台在基于数据查询请求确定图形数据使用者需要下载目标三维图形数据后，可向图形数据使用者提供付费接口(例如，云管理平台向图形数据使用者显示一个付款界面)，以通过付费接口获取图形数据使用者针对目标三维图像数据的付款，图形数据使用者付款时所需支付的金额通常等于目标三维图像数据的定价信息。云管理平台在确认图形数据使用者针对目标三维图像数据的付款成功后，说明图形数据使用者购买目标三维图像数据成功，再将目标三维图形数据提供给图形数据使用者。
在一种可能的实现方式中，该方法还包括：云管理平台将N个三维图形数据存储在对象存储设备中；则云管理平台在确认图形数据使用者针对目标三维图像数据的付款成功的前提下将目标三维图形数据提供给图形数据使用者，包括：云管理平台在确认图形数据使用者针对目标三维图像数据的付款成功的前提下将目标三维图形数据在对象设备中的访问地址提供给图形数据使用者，并针对图形数据使用者开放访问地址的读取权限。前述实现方式中，在确认图形数据使用者针对目标三维图像数据的付款成功后，说明图形数据使用者购买目标三维图像数据成功，云管理平台可将目标三维图形数据在对象存储设备的访问地址提供给图形数据使用者，并针对图形数据使用者开放该访问地址的读取权限。如此一来，图形数据使用者成功读取到该访问地址后，可基于该访问地址，从对象存储设备中拉取目标三维图像数据。
因此，本申请实施例提供了一种基于互联网的便捷的三维数据交易平台，云管理平台的不同登录者可按需上传渲染好的三维图像数据，并按需购买其他登录者的三维图像数据，能够节约三维图像数据开发及渲染时间，尤其是针对虚拟现实场景，当图形数据提供者将一个三维图像渲染好之后，在云管理平台中分享出来，图形数据使用者按需购买三维图像并应用在自己的三维场景中，可极大的节约渲染时间，并为图形数据使用者提供便利。
在一种可能的实现方式中，三维图形文件的格式为通用场景描述(USD)格式。

具体实施方式
本申请实施例提供了一种基于公有云的三维图形数据共享方法及云管理平台，云管理平台可满足图形数据使用者对特定三维图形数据的下载需求，向图形数据使用者提供其所需的三维图形数据，以充分服务图形数据使用者的业务。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
元宇宙基于互联网，它可以被理解为是人们所熟知的日常生活的数字版本。元宇宙的核心是一个基于现实世界的虚拟空间，也有人认为，元宇宙是和现实世界平行的平行世界。
元宇宙基于芯片技术、网络通信技术、虚拟现实技术(virtual reality，VR)、增强现实技术(augmented reality，AR)、混合现实(mixed reality，MR)、扩展现实技术(extended reality，XR))、游戏技术(游戏引擎、游戏代码、多媒体资源)、人工智能技术(artificial intelligence，AI)人工智能技术、区块链技术等各类技术，为用户提供了一个模拟现实世界的虚拟空间，以为用户提供沉浸式的体验。
当用户欲体验元宇宙提供的三维场景时(例如，某个虚拟的建筑物等等)，可先通过终端设备(例如，可穿戴设备、手机等等)，可先下载描述三维场景的文件(可以简称为三维图形文件)，例如，通用场景描述(USD)文件、OBJ文件以及GLTF文件等等。三维图形文件包含了已渲染的三维场景的图形数据。那么，终端设备下载三维图形文件后，可基于三维图形文件呈现出相应的三维场景，以提供给用户观看和体验。
相关技术中，由于三维图形文件通常是提前预置且固定的，用户的终端设备往往只能批量下载三维图形文件，并按这些文件的指示来呈现出相应的三维场景。可见，用户无法按照自身的需求，来灵活查询和获取某个三维场景的图形数据，从而渲染出使用者自身所需观看的三维场景。
进一步地，相关技术也无法在原有的三维图形文件的基础上进行修改，得到新的三维图形文件，只能从头构建一个新的三维图形文件，以供用户的终端设备呈现出新的三维场景，来满足用户的需求。
为了解决上述问题，本申请实施例提供了一种基于公有云的三维图形数据共享方法，该方法可通过如图1(图1为本申请实施例提供的公有云系统的一个结构示意图)所示的公有云系统实现，该公有云系统包括：云管理平台，云管理平台可供数据提供者和数据使用者接入，以分别与图形数据提供者、图形数据使用者实现通信。下文将对云管理平台、图形数据提供者和图形数据使用者进行介绍：
云管理平台，包含两大部分，第一部分为对象处理设备，第二部分为对象存储设备。对象处理设备和对象存储设备可以部署于同一台物理服务器上(例如，对象处理设备和对象存储设备为某一台物理服务器上的两个虚拟实例)，也可以部署于不同的物理服务器上，此处不做限制。对象处理设备可用于处理三维图形数据，例如，接收来自图形数据提供者的三维图形数据，又如，对三维图形数据进行更新，再如，将三维图形数据存储于对象存储设备中，还如，将三维图形数据发送至图形数据使用者等等。对象存储设备用于作为对象处理设备的数据库，能够用于存储三维图形数据以及与三维图形数据相关的其余信息。
云管理平台还可以在互联网上注册域名，图形数据提供者和图形数据使用者可通过访问云管理平台的域名来与云管理平台建立网络通信连接。
图形数据提供者，通常为应用开发者侧(例如，某些应用的开发者，这些应用可以为视频播放软件、游戏软件、仿真软件、元宇宙软件等等)的终端设备。图形数据提供者上部署有客户端(client)软件开发工具包(software development kit，SDK)，客户端SDK通常集成在应用中，图形数据提供者可通过客户端SDK与对象处理设备实现通信，例如，向对象处理设备上传三维图形数据，又如，向对象处理设备发送数据更新请求等等。
图形数据使用者，通常为用户侧(例如，使用某些应用的用户，这些应用可以为视频播放软件、游戏软件、仿真软件、元宇宙软件等等)的终端设备。图形数据使用者上同样部署有客户端软件开发SDK，客户端SDK通常集成在应用中，图形数据使用者可通过客户端SDK与对象处理设备实现通信，例如，向对象处理设备发送数据查询请求，并从对象处理设备处下载三维图形数据等等。
需要说明的是，对于图形数据提供者和图形数据使用者而言，云管理平台可视为服务端(server)，因为图形数据提供者和图形数据使用者上均部署有客户端SDK。
为了进一步理解云管理平台的工作流程，下面结合图2对该工作流程做进一步的介绍。图2为本申请实施例提供的基于公有云的三维图形数据共享方法的一个流程示意图，如图2所示，该方法包括：
201、云管理平台通过登录接口对N个图形数据提供者进行鉴权，N为大于1的正整数。
本实施例中，当N个图形数据提供者想上传三维图形数据(即三维场景的图形数据)时，云管理平台可向N个图形数据提供者提供登录接口，以通过登录接口对N个图形数据提供者进行鉴权，N为大于1的正整数。具体地，云管理平台可通过多种方式对N个图形数据提供者进行鉴权，下文将分别进行介绍：
在一种可能的实现方式中，当登录接口为云管理平台所提供的面向N个图形数据提供者的登录界面时，云管理平台可通过该登录界面接收来自N个图形数据提供者的账号和密码(这N个图形数据提供者输入的账号和密码已在云管理平台处完成了注册)，从而对N个图形数据提供者的帐号和密码进行身份验证，若对图形数据提供者的身份验证成功(即对图形数据提供者的鉴权成功)，云管理平台可允许N个图形数据提供者登录云管理平台，以执行步骤202。例如，如图3所示(图3为本申请实施例提供的登录界面的一个示意图)，在开发者1渲染出元宇宙中三维场景1的图形数据(即元宇宙中三维图形数据1，三维场景1可以为元宇宙中模型某个学校的虚拟空间或模拟某个火车站的虚拟空间等等，此处不做限制)后，若开发者1想将三维场景1的图形数据上传云管理平台，开发者1可在云管理平台提供的登录 界面1中，向身份类型输入栏输入自身的类型为图形数据提供者，并分别向账户输入栏和密码输入栏输入自身的账户和自身的密码。云管理平台通过登录界面1接收到开发者1的账户和开发者1的密码后，可基于这部分信息对开发者1的图形数据提供者身份进行验证，若验证成功(即鉴权成功)，则允许开发者1以图形数据提供者的身份登录云管理平台，并执行步骤202，若验证失败(即鉴权失败)，则在登录界面1上显示身份验证失败的弹窗，以提醒开发者1重新进行身份验证。
在另一种可能的实现方式中，当登录接口为云管理平台向N个图形数据提供者暴露的通信接口时，云管理平台还可通过该通信接口，以证书的方式对N个图形数据提供者进行身份验证，若对N个图形数据提供者的身份验证成功(即对图形数据提供者的鉴权成功)，云管理平台可允许N个图形数据提供者登录云管理平台，以执行步骤202。
202、在鉴权成功后，N个图形数据提供者通过云管理平台提供的上传接口向云管理平台发送N个三维图形数据和N个三维图形数据的属性信息，其中，N个三维图形数据为已经渲染好的N个三维图形文件。
在对N个图形数据提供者的鉴权成功后，云管理平台允许N个图形数据提供者登录云管理平台，并向N个图形数据提供者提供上传接口(也可以称为三维图形数据上传接口)，以通过上传接口接收来自N个图形数据提供者输入的N个三维图形数据以及N个三维图形数据的属性信息，即对于N个图形数据提供者中的任意一个图形数据提供者而言，该图形数据提供者可通过上传接口，向云管理平台上传三维图形数据和该三维图形数据的属性信息。对于除该图形数据提供者之外的其余图形数据提供者，也是如此，故云管理平台总共可得到N个三维图形数据和这N个三维图形数据的属性信息。
需要说明的是，对于任意一个三维图形数据而言，该三维图形数据可通过已经渲染好的三维图形文件的形式进行上传，已经渲染好的三维图形文件可以是USD文件，也可以是OBJ文件，还可以是GLTF文件。由于该三维图形数据对应三维场景中，通常包含至少一个物体，那么，该三维图形数据通常包含至少一个物体的图形数据，对于任意一个物体而言，该物体的图形数据包含该物体的ID、该物体的几何信息(例如，顶点坐标、顶点索引、法线坐标等等)、该物体的材质信息、该物体的纹理信息、该物体的位置信息(该物体中心点在三维场景中的坐标、该物体在三维场景中所呈现的角度等等)、该物体的光源信息、该物体的文本标签以及该物体的时间标签等等。
该三维图形数据的属性信息可以认为该三维图形数据的索引，该三维图形数据的索引可以为以下至少一项：该三维图形数据对应的三维场景的ID，该三维图形数据中物体的标识(例如，物体的ID，物体的文本标签，物体的时间标签等等)以及物体在该三维场景中的空间信息(例如，物体的位置信息，基于物体的几何信息计算得到的结果等等)。例如，假设元宇宙中三维场景1存在一个物体youruuid，云管理平台可将三维场景1的ID“firstScene”、该物体的ID“youruuid”、该物体的文本标签“t1”、该物体的时间标签“2021-02-0312:00:00”、该物体在三维场景1中的坐标“[0,0,0]”均可作为三维场景1的图形数据的索引。
进一步地，云管理平台还可通过上传接口接收来自N个图形数据提供者输入的针对N个三维图形数据的定价信息。即对于N个图形数据提供者中的任意一个图形数据提供者而言， 该图形数据提供者可通过上传接口，不仅向云管理平台上传三维图形数据和该三维图形数据的属性信息，还可向云管理平台上传该三维图形数据的定价信息。对于除该图形数据提供者之外的其余图形数据提供者，也是如此，故云管理平台不仅可得到N个三维图形数据和这N个三维图形数据的属性信息，还可得到这N个三维图形数据的定价信息。
为了便于说明，下文均以登录接口为面向N个图形数据提供者的登录界面进行示意性介绍。设上传接口为上传界面，在云管理平台允许N个图形数据提供者登录云管理平台后，云管理平台可向N个图形数据提供者提供上传界面(在N个图形数据提供者侧，相当于从登录界面跳转至上传界面)，并通过上传界面接收来自N个图形数据提供者的N个三维图形数据和N个三维图形数据的属性信息。
依旧如上述例子，如图4所示(图4为本申请实施例提供的主界面的一个示意图，图4是在图3的基础上进行绘制的)，开发者1成功登陆云管理平台后，则从登录界面1跳转至主界面1，主界面1可基于开发者1的指令进一步跳转至各个分界面，例如，上传界面等等。那么，当开发者1要上传三维场景1的图形数据时，可在主界面1中点击“数据上传”，以从主界面1跳转至上传界面(如图5所示，图5为本申请实施例提供的上传界面的一个示意图)，并在上传界面中的数据输入栏、属性信息输入栏和定价信息输入栏中，分别输入三维场景1的图形数据、三维场景1的图形数据的属性信息以及三维场景1的图形数据的定价信息。如此一来，云管理平台可通过上传界面，获取到开发者1上传的三维场景1的图形数据、三维场景1的图形数据的属性信息以及三维场景1的图形数据的定价信息。
应理解，若云管理平台和N个图形数据提供者之间是通过证书的方式实现身份验证的，登录接口和上传接口通常为同一接口(即同一通信接口)，该接口不仅可用于身份验证，还可用于上传三维图形数据。若云管理平台和N个图形数据提供者之间是通过账户密码的方式实现身份验证的，登录接口和上传接口通常不同接口(即登录界面和上传界面)，其中一个接口用于身份验证，另一个接口用于上传三维场景的数据。
203、云管理平台将N个三维图形数据存储于数据库中。
云管理平台接收到来自N个图形数据提供者的N个三维图形数据后，可将N个三维图形数据存储于数据库(即前述的对象存储设备)中，以供后续图形数据使用者来查询和调用。具体地，云管理平台存储N个三维图形数据的方式可以为：
(1)云管理平台在数据库中创建一个子库，并导入N个三维图形数据，如此一来，该子库则存储有N个三维图形数据。进一步地，云管理平台还可为N个三维图形数据配置唯一标识(例如，这N个三维图形数据对应的三维场景的ID)来标记该子库，故云管理平台可通过N个三维图形数据的标识来打开存储有N个三维图形数据的子库，即打开这N个三维场景。依旧如上述例子，云管理平台可创建一个子库，并导入数据：
Figure PCTCN2022139453-appb-000001
其中，"firstScene"即为三维场景1的ID，那么，云管理平台可通过"firstScene"来打 开三维场景1：
Scene firstScene＝openScene(
   name:"firstScene"
)
(2)一般地，不同的三维图形数据通常存储于子库中的不同存储区域，为了快速准确地获取某个三维图形数据，云管理平台可利用这N个三维图形数据的索引，来定位到这N个三维图像数据的存储区域。在这N个三维图形数据的索引中，任意一个物体的图形数据的索引可用于定位到子库中存储有该物体的图形数据的存储区域。
值得注意的是，云管理平台也可将N个三维图形数据的索引存储于子库中。需要说明的是，不同类型的索引在子库中的存储形式不同，例如，三维场景的ID、物体的ID、物体的时间标签、物体在三维场景中的坐标等这种类型的索引可通过树结构来存储，而物体的文本标签等这种类型的索引可通过倒排序索引来存储。
那么，当云管理平台需要获取某个三维图形数据时，在打开子库后，可基于该三维图形数据的索引，快速定位到该子库中存储有该三维图形数据的存储区域，并从中获取该三维图形数据。
204、云管理平台通过登录接口对图形数据使用者进行鉴权。
当图形数据使用者想下载目标三维图形数据时，云管理平台可向图形数据使用者提供登录接口，以通过登录接口对图形数据使用者进行鉴权。具体地，云管理平台可通过多种方式对图形数据使用者进行鉴权，下文将分别进行介绍：
在一种可能的实现方式中，当登录接口为云管理平台所提供的面向图形数据使用者的登录界面时，云管理平台可通过该登录界面接收来自图形数据使用者的帐号密码，从而对图形数据使用者的帐号密码进行身份验证，若对图形数据使用者的身份验证成功(即对图形数据使用者的鉴权成功)，云管理平台可允许图形数据使用者登录云管理平台，以执行步骤205。例如，如图6所示(图6为本申请实施例提供的登录界面的另一示意图)，用户在云管理平台提供的登录界面2中，可在身份类型输入栏中输入自身的类型为图形数据使用者，并分别在账户输入栏和密码输入栏中输入自身的账户和自身的密码。云管理平台通过登录界面2接收到用户的账户和用户的密码后，可基于这部分信息对用户的图形数据使用者身份进行验证，若验证成功(即鉴权成功)，则允许用户以图形数据使用者的身份登录云管理平台，并执行步骤205，若验证失败(即鉴权失败)，则在登录界面2上显示身份验证失败的弹窗，以提醒用户重新进行身份验证。
在另一种可能的实现方式中，当登录接口为云管理平台向图形数据使用者暴露的通信接口时，云管理平台还可通过该通信接口，以证书的方式对图形数据使用者进行身份验证，若对图形数据使用者的身份验证成功(即对图形数据使用者的鉴权成功)，云管理平台可允许图形数据使用者登录云管理平台，以执行步骤205。
205、在鉴权成功后，云管理平台向图形数据使用者提供N个三维图形数据的介绍页面，介绍页面用于显示N个三维图形数据的介绍信息，N个介绍信息包含N个三维图形数据的属性信息。
206、图形数据使用者通过云管理平台提供的数据确定接口向云管理平台请求N个三维图 形数据中的目标三维图形数据。
207、云管理平台将数据库中的目标三维图形数据提供给图形数据使用者。
在对图形数据使用者的鉴权成功后，云管理平台允许图形数据使用者登录云管理平台，并向图形数据使用者提供N个三维图形数据的介绍页面(也可称为介绍界面)。该介绍页面包含数据确定接口(例如，介绍页面中不仅展示了N个三维图形数据的介绍信息，N个介绍信息包括N个三维图形数据的属性信息(索引)，介绍页面还展示了数据确定接口，该接口可接收图形数据使用者的数据查询请求)，数据确定接口可用于从N个三维图形数据中确定满足图形数据使用者需求的目标三维图形数据。若云管理平台通过介绍页面的数据确定接口检测到图形数据使用者请求目标三维图形数据，则将数据库中的目标三维图形数据发送给图形数据使用者，故图形数据使用者可使用这些图形数据呈现出相应的三维场景。需要说明的是，目标三维图形数据可以已经渲染好的三维图形文件的形式发送给图形数据使用者，三维图形文件可以是USD文件，也可以是OBJ文件，还可以是GLTF文件，甚至可以是自定义格式的文件，此处不做限制。
为了便于说明，下文均以登录接口为面向图形数据使用者的登录界面进行示意性介绍。设数据确定接口为介绍界面中的数据查询输入栏，在云管理平台允许图形数据使用者登录云管理平台后，云管理平台可向图形数据使用者提供介绍界面(在图形数据使用者侧，相当于从登录界面跳转至介绍界面)。图形数据使用者在浏览介绍界面展示的N个三维图形数据的介绍信息后，可找到自身所需的三维图形数据以及该三维图形数据的属性信息(索引)，以此作为图形数据使用者所需的三维图形数据的需求信息(例如，图形数据使用者针对某个三维图形数据所设定的索引范围)来生成数据查询请求，并向介绍界面中的数据查询输入栏输入该数据查询请求。那么，云管理平台通过下载界面接收到数据查询请求后，可基于数据查询请求确定该需求信息(即索引范围)。然后，云管理平台打开子库，找到符合需求信息的目标属性信息(即位于索引范围中的目标索引)，并基于目标属性信息，定位到子库中存储有相应三维图形数据的存储区域，从中获取该三维图形数据，该三维图形数据即为目标三维图形数据。最后，云管理平台将这目标三维图形数据返回给图形数据使用者，至此，图形数据使用者成功下载了其所需的目标三维图形数据。
依旧如上述例子，如图7所示(图7为本申请实施例提供的介绍界面的一个示意图，图7是在图6的基础上进行绘制的)，用户成功登陆云管理平台后，则从登录界面2跳转至介绍界面，介绍界面展示有元宇宙中多个三维场景的图形数据的介绍信息，如三维场景1的图形数据的介绍信息(由开发者1提供)，三维场景2的图形数据的介绍信息(由开发者2提供)等等。用户浏览这些信息后，确定三维场景1为其想要体验的场景，故需要下载三维场景1的图形数据，那么，用户可在介绍界面中的数据查询输入栏处，按照自身的需求数据查询请求，相当于向云管理平台发送数据查询请求，该请求用于指示用户针对三维场景1所选定的索引范围，例如，该请求携带场景ID“firstScene”，表明用户需要获取三维场景1的图形数据。云管理平台在子库中查询过后，可确定三维场景1的图形数据的索引落于该索引范围内，(即三维场景1的ID与该请求携带的场景ID相匹配)，说明用户需要下载三维场景1的图形数据。故云管理平台可基于该索引，定位到存储有三维场景1的图形数据的存储区域，从中获取三维场景1的图形数据，并将该数据返回给用户。
进一步地，云管理平台可通过以下方式将目标三维图形数据，提供给图形数据使用者：
云管理平台在基于数据查询请求确定图形数据使用者需要下载目标三维图形数据后，可向图形数据使用者提供付费接口(例如，云管理平台向图形数据使用者显示一个付款界面)，付费接口用于获取图形数据使用者针对目标三维图像数据的付款，图形数据使用者付款时所需支付的金额通常等于目标三维图像数据的定价信息。云管理平台在确认图形数据使用者针对目标三维图像数据的付款成功后，说明图形数据使用者购买目标三维图像数据成功，再将目标三维图形数据提供给图形数据使用者。
依旧如上述例子，云管理平台确定用户需要三维场景1的图形数据后，可先向用户展示一个如图8所示的付款界面(图8为本申请实施例提供的付款界面的一个示意图)，付款界面显示有付款码，当用户扫描该付款码，并支付购买三维场景1的图形数据所需的金额后，云管理平台才将三维场景1的图形数据提供给用户。
更进一步地，在图形数据使用者针对目标三维图像数据的付款成功后，云管理平台还可通过以下方式将目标三维图形数据，提供给图形数据使用者：
在确认图形数据使用者针对目标三维图像数据的付款成功后，说明图形数据使用者购买目标三维图像数据成功，云管理平台可将目标三维图形数据在数据库(即前述的对象存储设备)中的访问地址提供给图形数据使用者，并针对图形数据使用者开放该访问地址的读取权限。如此一来，图形数据使用者成功读取到该访问地址后，可基于该访问地址，从数据库中拉取目标三维图像数据。
依旧如上述例子，云管理平台确定用户已支付购买三维场景1的图形数据所需的金额后，云管理平台可向用户返回数据库的访问地址，并开放给用户读取。用户读取该访问地址后，可通过该访问地址访问云管理平台的数据库中存储有三维场景1的图形数据的存储区域，从该存储区域中获取三维场景1的图形数据，完成三维场景1的图形数据的下载。
应理解，上述例子仅以用户请求三维场景1的图形数据进行示意性介绍，在实际应用中，用户还可以请求其余三维图形数据，例如，三维场景2的图形数据等等。
还应理解，上述例子仅以用户利用三维场景的ID来构建索引范围进行示意性介绍，在实际应用中，用户还可利用物体在三维场景中的坐标、物体的文本标签、物体的时间标签、物体的ID等等信息来构建索引范围。
应理解，若云管理平台和图形数据使用者之间是通过证书的方式实现身份验证的，登录接口和数据确定接口通常为同一接口(即同一通信接口)，该接口不仅可用于身份验证，还可用于下载三维图形数据。若云管理平台和图形数据使用者之间是通过账户密码的方式实现身份验证的，登录接口和数据确定接口通常不同接口(即登录界面和介绍界面中的数据查询输入栏)，其中一个接口用于身份验证，另一个接口用于下载三维场景的数据。
本申请实施例中，当N个图形数据提供者想上传三维图形数据时，云管理平台可提供上传接口，以通过上传接口接收来自N个图形数据提供者的N个三维图形数据和N个三维图形数据的属性信息。接着，云管理平台可向图形数据使用者提供N个三维图形数据的介绍页面，该介绍页面用于显示N个三维图形数据的介绍信息，N个介绍信息包括N个三维图形数据的属性信息。当图形数据使用者想下载N个三维图形数据中的目标三维图形数据时，可通过云管理平台提供的数据确定接口通知云管理平台，以使得云管理平台将目标三维图形数据提供 给图形数据使用者，使得图形数据使用者可基于目标三维图形数据呈现出相应的三维场景。由此可见，云管理平台可采集不同图形数据提供者自由上传的各个三维图形数据。当图形数据使用者需要其中某个三维图形数据时，云管理平台可满足图形数据使用者对特定三维图形数据的下载需求，向图形数据使用者提供其所需的三维图形数据，以充分服务图形数据使用者的业务。
图9为本申请实施例提供的基于公有云的三维图形数据共享方法的另一流程示意图，如图9所示，该方法包括：
901、云管理平台通过登录接口对N个图形数据提供者进行鉴权，N为大于1的正整数。
902、在鉴权成功后，N个图形数据提供者通过云管理平台提供的上传接口向云管理平台发送N个三维图形数据和N个三维图形数据的属性信息，其中，N个三维图形数据为已经渲染好的N个三维图形文件。
903、云管理平台将N个三维图形数据存储于数据库中。
关于步骤901至步骤903的说明，可参考图2所示实施例中步骤201至步骤203的相关说明部分，此处不再赘述。
904、云管理平台通过上传接口接收图形数据提供者的数据更新请求，并基于数据更新请求，对目标三维图形数据进行更新，得到更新后的三维图形数据。
本实施例中，当图形数据提供者需要更新目标三维图形数据时，可通过上传接口向云管理平台发送针对目标三维图形数据的数据更新请求(即前述的三维图形数据更新请求)。需要说明的是，数据更新请求用于指示图形数据提供者对目标三维图形数据的一种或多种更新操作，例如，图形数据提供者需在要目标三维图形数据中，加入某个(或某些)新物体的图形数据，这种情况下的更新操作为数据增加操作，又如，图形数据提供者需要在目标三维图形数据中，删除某个(或某些)已有物体的图形数据，这种情况下的更新操作为数据删除操作，再如，图形数据提供者需要在目标三维图形数据中，修改某个(或某些)已有物体的图形数据，这种情况下的更新操作为修改操作。
值得注意的是，本申请实施例中，上传接口可实现多种功能，在步骤902中，上传接口用于实现三维图形数据的上传，上传接口可呈现为一个上传界面。而在步骤904中，上传接口用于实现三维图形数据的更新，上传接口可呈现为一个更新界面。
例如，开发者1(当然也可以是开发者2等其余开发者)发现需要更新三维场景1的图形数据时，可再次登录云管理平台，并进入主界面1，接着在主界面1中点击“数据更新”，以从主界面1跳转至更新界面(如图10所示，图10为本申请实施例提供的更新界面的一个示意图)。然后，开发者1可更新界面中的场景输入栏中，输入三维场景1，并在更新内容输入栏中输入所需更新的内容，相当于通过更新界面向云管理平台发送数据更新请求，该请求用于指示开发者1针对三维场景1的更新内容，例如，该请求携带场景ID“firstScene”、增加操作的标识“addMesh”、增加的物体的ID“myuuid”以及该物体的几何信息等等，表明开发者1想在三维场景1中添加新的物体myuuid的图形数据，又如，该请求携带场景ID“firstScene”、删除操作的标识“deleteObject”以及文本标签“tag＝“t1””等等，表明开发者1想在三维场景1中，将所有具备这个文本标签的物体的图形数据删除。再如，该请求携带场景ID“firstScene”、修改操作的标识“modifyMesh”、修改的物体的ID“youruuid” 以及该物体在三维场景1中的坐标“[0,1,0]”等等，表明开发者1想在三维场景1中，修改物体youruuid的位置等等。
云管理平台得到数据更新请求后，可基于该请求对数据库中的三维场景的图形数据进行更新操作，得到更新后的三维图形数据，更新操作具体为哪一种操作，可依据数据更新请求来确定。
依旧如上述例子，云管理平台基于数据更新请求，确定需在三维场景1中添加新物体myuuid的图形数据时，可在存储有三维场景1的图形数据的子库中，执行以下增加操作：
Figure PCTCN2022139453-appb-000002
完成上述增加操作后，则在原有三维场景1的图形数据中，增加了新物体myuuid的图形数据，故子库中存储有增加数据后的三维场景1的图形数据。
又如，云管理平台基于数据更新请求，确定需在三维场景1中，将所有具备这个文本标签的物体的图形数据删除，可在存储有三维场景1的图形数据的子库中，执行以下删除操作：
firstScene.deleteObject(
   where:tag＝"t1"
)
完成上述删除操作后，则在原有三维场景1的图形数据中，删除了所有文本标签为t1的物体的图形数据，故子库中存储有删除数据后的三维场景1的图形数据。
再如，云管理平台基于数据更新请求，确定需在三维场景1中，修改物体youruuid的位置，可在存储有三维场景1的图形数据的子库中，执行以下修改操作：
Figure PCTCN2022139453-appb-000003
完成上述修改操作后，则在原有三维场景1的图形数据中，修改了物体youruuid的位置，故子库中存储有修改数据后的三维场景1的图形数据。
完成目标三维图形数据的更新后，在N个三维图形数据中，原先的目标三维图形数据将更换为更新后的三维图形数据。
905、云管理平台通过登录接口对图形数据使用者进行鉴权。
906、在鉴权成功后，云管理平台向图形数据使用者提供N个三维图形数据的介绍页面，介绍页面用于显示N个三维图形数据的介绍信息，N个介绍信息包含N个三维图形数据的属性信息。
907、图形数据使用者通过云管理平台提供的数据确定接口向云管理平台请求N个三维图形数据中的更新后的三维图形数据。
908、云管理平台将数据库中更新后的三维图形数据提供给图形数据使用者。
关于步骤905至步骤908的说明，可参考图2所示实施例中步骤204至步骤207的相关说明部分，此处不再赘述。需要说明的是，步骤906和步骤205的区别在于，步骤906中N个三维图形数据包含更新后的三维图形数据，但不包含目标三维图形数据，步骤205中N个三维图形数据不包含更新后的三维图形数据，但包含目标三维图形数据。步骤907和步骤206的区别在于，步骤907中图形数据使用者请求的是更新后的三维图形数据，步骤206中图形数据使用者请求的是目标三维图形数据。步骤908和步骤207的区别在于，步骤907中云管理平台向图形数据使用者提供的是更新后的三维图形数据，步骤206中云管理平台向图形数据使用者提供的是目标三维图形数据。
值得注意的是，本申请实施例中所提及的，云管理平台对外暴露的所有接口(包含登录接口、上传接口、数据确定接口等等)均是供互连网上的公有云租户访问的，公有云租户为在云管理平台注册的租户，该租户既可以是图形数据提供者，也可以是图形数据使用者。
本申请实施例中，当N个图形数据提供者想上传三维图形数据时，云管理平台可提供上传接口，以通过上传接口接收来自N个图形数据提供者的N个三维图形数据和N个三维图形数据的属性信息。接着，云管理平台可向图形数据使用者提供N个三维图形数据的介绍页面，该介绍页面用于显示N个三维图形数据的介绍信息，N个介绍信息包括N个三维图形数据的属性信息。当图形数据使用者想下载N个三维图形数据中的目标三维图形数据时，可通过云管理平台提供的数据确定接口通知云管理平台，以使得云管理平台将目标三维图形数据提供给图形数据使用者，使得图形数据使用者可基于目标三维图形数据呈现出相应的三维场景。由此可见，云管理平台可采集不同图形数据提供者自由上传的各个三维图形数据。当图形数据使用者需要其中某个三维图形数据时，云管理平台可满足图形数据使用者对特定三维图形数据的下载需求，向图形数据使用者提供其所需的三维图形数据，以充分服务图形数据使用者的业务。
更进一步地，图形数据提供者还可对云管理平台提供的数据库中的三维图形数据进行更新，如此一来，不同数据提供者可协同合作，在数据库中原有的三维图形数据的基础上进行增加、删除和修改等操作，得到新的三维图形数据，从而提高了三维场景构建的便捷性，且能减少开发成本。
