具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然， 所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
通常通过建立并展示人体的三维模型，以让人们能够了解人体整体以及人体的各部分结构。在通过三维软件的建模过程中，一般采用多边形(例如，三角形)构建人体的三维模型，用这种方法创建的人体三维模型的表面包括多个多边形，多边形的数量越多，该人体三维模型的面数越多，面数越多，数据量越大，系统的处理速度越慢。为了减少系统的数据处理量，提高系统的处理速度，目前对人体三维模型的减面方法主要包括两种：第一种方法是直接在三维软件中手动优化人体三维模型，以实现减面；第二种方法是通过设置人体三维模型的显示面数的预设值，以在三维软件中实现自动减面。
但是，上述两种对人体三维模型的减面方法分别包括如下缺陷：第一种方法虽然步骤简洁，但是需要人工手动减面，其耗费的人力和时间较大，且对于复杂的三维模型，人工操作的难度也非常大；第二种方法虽然速度较快，但是该方案仅能够控制人体三维模型的显示面数，人体三维模型的其他方面的可控数据(例如，对显示细节的要求等数据)较少，减面后无法实现预期的效果，显示效果较差。图1A为一种减面后的显示模型的效果图。当对人体三维模型减面过多时，会出现图1A所示的情况，例如，根据减面程度的差异，减面后的人体三维模型上的相接但未焊接的顶点的部分会出现不同缝隙。另外，当当模型数量巨大时，难以进行模型的减面处理。
本公开至少一实施例提供一种显示处理方法，包括：获取待显示对象的基础模型的多个子模型，每个子模型包括多个面；获取待显示对象的显示环境参数；基于显示环境参数，对于多个子模型中的每个子模型，确定该子模型的显示细节层级，并基于所确定的该子模型的显示细节层级，确定该子模型的显示面数；对于多个子模型中的每个子模型，基于所确定的该子模型的显示面数，确定该子模型的显示子模型。
本公开一些实施例还提供对应于上述显示处理方法的显示处理装置和存储介质。
本公开上述实施例提供的显示处理方法可以基于显示环境和显示细节层级确定各个子模型的显示面数，从而可以在减少各个子模型的显示面数的同时，增加各个子模型的可控数据(例如，显示细节层级等)，提高了待显示对象的显示效果，减少了系统的数据处理量，降低了资源消耗。
下面结合附图对本公开的实施例及其示例进行详细说明。
本公开至少一实施例提供一种显示处理方法，例如，可以应用于展示人体三维模型等。图1B为本公开至少一实施例提供的一种显示处理方法的一个示例的流程图。例如，该显示处理方法可以以软件、硬件、固件或其任意组合的方式实现，由例如手机、平板电脑、笔记本电脑、桌面电脑、网络服务器等设备中的处理器加载并执行，可以在减少人体三维模型的显示面数的同时，增加人体三维模型的可控数据，提高了人体三维模型的显示效果。
例如，该显示处理方法适用于一计算装置，该计算装置是包括具有计算功能的任何电子设备，例如可以为手机、笔记本电脑、平板电脑、台式计算机、网络服务器等，可以加载并执行该显示处理方法，本公开的实施例对此不作限制。例如，该计算装置可以包括中央处理单元(Central Processing Unit，CPU)或图形处理单元(Graphics Processing Unit，GPU)等具有具有数据处理能力和/或指令执行能力的其它形式的处理单元、存储单元等，该计算装置上还安装有操作系统、应用程序编程接口(例如，OpenGL(Open Graphics Library)、Metal等)等，通过运行代码或指令的方式实现本公开实施例提供的显示处理方法。例如，该计算装置还可以包括显示部件，该显示部件例如为液晶显示屏(Liquid Crystal Display，LCD)、有机发光二极管(Organic Light Emitting Diode，OLED)显示屏、量子点发光二极管(Quantum Dot Light  Emitting Diode，QLED)显示屏、投影部件、VR头戴式显示设备(例如VR头盔、VR眼镜)等，本公开的实施例对此不作限制。例如，该显示部件可以显示待显示对象。
如图1B所示，该显示处理方法包括步骤S110至步骤S140。
步骤S110：获取待显示对象的基础模型的多个子模型，每个子模型包括多个面。
步骤S120：获取待显示对象的显示环境参数。
步骤S130：基于显示环境参数，对于多个子模型中的每个子模型，确定该子模型的显示细节层级，并基于所确定的该子模型的显示细节层级，确定该子模型的显示面数。
步骤S140：对于多个子模型中的每个子模型，基于所确定的该子模型的显示面数，确定该子模型的显示子模型。
对于步骤S110，例如，在一些示例中，待显示对象为人体，基础模型为人体三维模型(如图2A所示)。当然，待显示对象还可以是其他可以显示的动物、植物以及物体等，本公开的实施例对此不做限制。下面以待显示对象为人体，基础模型为人体三维模型为例进行说明，本公开的实施例对此不作限制。
例如，在一些示例中，在打开电子设备进入人体信息展示的显示界面(例如，打开数字人体APP)后，该优化后的人体三维模型(即显示模型)在电子设备上进行展示。
例如，在一些示例中，将待显示对象的基础模型导入图像渲染引擎(即渲染器，例如，包括二维图像引擎或三维图像引擎，例如，图像处理器(GPU))，并通过图像渲染引擎将待显示对象的基础模型拆分为多个子模型。例如，图像渲染引擎向下面介绍的第一获取单元提供该多个子模型，以在后续步骤中对该多个子模型进行处理以确定该多个子模型的显示子模型。例如，该图像渲染引擎包括虚幻4引擎(Unreal Engine4，简称UE4)。下面以图像渲染引擎为UE4为例进行说明，本公开的实施例对此不作限制。
需要注意的是，还可以根据需要实现的功能将待显示对象的基础模型导入物理引擎、脚本引擎或网络引擎等其他类型的引擎中进行拆分处理，本公开的实施例对此不作限制。
例如，基础模型为人体三维模型，人体三维模型中包括人体器官类别信息、人体系统类别信息或人体参数信息。例如，人体三维模型按照器官进行分类，可以包括心、肝脏、脾、肺、肾等各个器官的三维模型，按照人体系统类别进行分类，可以包括循环系统、消化系统、呼吸系统、生殖系统、免疫系统等系统的三维模型，也可按照局部进行分类，包括头部、胸部、上下肢等局部系统的三维模型。
例如，将器官肝脏的三维模型拆分为不能再继续拆分的多个元素，例如，可以拆分为肝和脏下面不能再继续拆分的元素，器官肝脏的三维模型的多个子模型与该多个元素一一对应，即针对拆分的每个元素形成一个子模型。
例如，每个子模型包括多个面。由于在通过三维软件的建模过程中，一般采用多边形(例如，三角形)构建人体的三维模型，用这种方法创建的人体三维模型的表面包括多个多边形，因此，被拆分的多个子模型中的每个子模型的表面也包括多个多边形，即每个子模型包括多个面。
在下面的步骤中，对每个子模型分别进行优化减面，即分别确定各个子模型的显示面数，以确定各个子模型的显示子模型，从而减少最终的人体三维模型的显示面数。
例如，可以提供第一获取单元，并通过该第一获取单元获取待显示对象的基础模型的多个子模型，例如，从图像渲染引擎中获取该多个子模型；例如，也可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现该第一获取单元。例如，该处理单元可以为通用处理器或专用处理器，可以是基于X86或ARM架构的处理器等。
例如，在图像渲染引擎将待显示对象的基础模型拆分为多个子模型后，通过插件从图像渲染引擎(例如，UE4)中获取待显示对象的多个子模型，并通过插件分别确定多个子模型的显示子模型，即在插件中执行相应的指令以实现后续步骤S120-步骤S140。例如，在一些示例中，该插件可以是针对图像渲染引擎开发的，以实现对应的功能。
对于步骤S120，例如，待显示对象的显示环境参数包括待显示对象的显示模型在显示界面中需要呈现的位置、角度和距离显示屏幕的距离等。
例如，该显示屏幕相当于虚拟相机，待显示对象的显示模型距离显示屏幕的距离即待显示对象的显示模型在3维空间中距离该虚拟相机的距离。
例如，待显示对象的显示环境参数包括：在近距离显示子模型，即扩大显示该子模型时，待显示对象的显示模型在显示界面中需要呈现的位置靠近显示屏幕，即待显示对象的显示模型距离显示屏幕的距离较小，例如，记作第二距离；在远距离显示该子模型，即缩小显示该子模型时，待显示对象的显示模型在显示界面中需要呈现的位置远离显示屏幕，即待显示对象的显示模型距离显示屏幕的距离较大，例如，记作第一距离(例如，第一距离大于第二距离)。具体介绍可参考下面图2B中的介绍，在此不再赘述。
例如，可以提供第二获取单元，并通过该第二获取单元获取待显示对象的显示环境参数；例如，也可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现该第二获取单元。
对于步骤S130，例如，显示细节层级可以通过LOD(Levels of Detail，多细节层次)技术获得。LOD技术指根据物体模型的节点在显示环境中所处的位置和重要度，决定物体渲染的资源分配，降低非重要物体的面数和细节度，提高重要物体的面数和细节度，从而获得高效率的渲染运算。例如，LOD1为第一显示层级，LOD2为第二显示层级，LOD3为第三显示层级，以此类推。
例如，对于多个子模型中的每个子模型，基于步骤S120中获取的显示环境参数，确定该子模型的显示细节层级。
图2B为本公开至少一实施例提供的一种确定子模型的显示面数的方法的流程图。也就是说，图2B为图1B中所示的步骤S130的一些示例的流程图。例如，在图2B所示的示例中，该确定方法包括步骤S131至步骤S133。下面，结合图2B对本公开至少一实施例提供的显示处理方法进行详细地介绍。
步骤S131：对于多个子模型中的每个子模型，将该子模型的显示细节层级分为第一显示层级和第二显示层级。
步骤S132：在采用第一距离显示该子模型时，采用第一显示层级确定该 子模型的显示面数。
步骤S133：在采用第二距离显示该子模型时，采用第二显示层级确定该子模型的显示面数。
例如，第一距离和第二距离表示子模型至显示屏幕的距离，第一距离大于第二距离。
对于步骤S131，例如，在一些示例中，第一显示层级和第二显示层级分别表示子模型的显示面数(即显示子模型的面数)和子模型的原本的面数的百分比。例如，在一些示例中，第二显示层级大于第一显示层级，即第二显示层级对应的子模型的显示面数多于第一显示层级对应的子模型的显示面数，因此，采用第二显示层级确定的显示子模型的细节度的展示更高，因此，更适合近距离展示(例如，放大展示)；采用第一显示层级确定的显示子模型的细节度的展示较低，因此，更适合远距离展示(例如，缩小展示)。例如，第二显示层级为40％(例如，子模型的面数为1000，子模型的显示面数(显示子模型的面数)为400)，第一显示层级为10％(例如，子模型的面数为1000，子模型的显示面数(例如，显示子模型的面数)为100)。
需要注意的是，还可以继续将显示细节层级分为第三显示层级和第四显示层级等，本公开的实施例对此不作限制。
对于步骤S132，例如，在采用第一距离显示该子模型时，即远距离显示该子模型时，采用较低的显示层级(例如，第一显示层级)确定该子模型的显示面数，从而可以确定显示面数较少的显示子模型。
例如，在系统中设置第一显示层级的预设值，在采用第一距离显示该子模型时，调用该第一显示层级的预设值设置该子模型的显示面数。
对于步骤S133，例如，在采用第二距离显示该子模型时，即近距离显示该子模型时，采用较高的显示层级(例如，第二显示层级)确定该子模型的显示面数，从而可以确定显示面数较多的显示子模型，即采用第一显示层级确定的该子模型的显示面数少于采用第二显示层级确定的该子模型的显示面数。
例如，在系统中设置第二显示层级的预设值，在采用第二距离显示该子模型时，调用该第二显示层级的预设值设置该子模型的显示面数。
例如，当接收到扩大展示该子模型的指令时，例如，手指或鼠标在电子 设备的显示界面(例如，数字人体APP的界面)点击扩大展示该子模型的按钮时，展示通过步骤S133获取的显示面数确定的显示子模型；当接收到缩小展示该子模型的指令时，例如，手指或鼠标在电子设备的显示界面(例如，数字人体APP的界面)点击缩小展示该子模型的按钮时，展示通过步骤S132获取的显示面数确定的显示子模型。
例如，可以根据实际情况设置距离的预设阈值，当显示距离(子模型距离显示屏幕的距离)大于该预设阈值时，即采用第一距离显示子模型，当显示距离小于该预设阈值时，即采用第二距离显示子模型，本公开的实施例对此不作限制。
根据显示环境参数，例如，该子模型的显示位置至显示屏幕的距离，确定显示细节层级，例如，扩大展示子模型(采用第二距离显示子模型)时，采用数值较大的第二显示层级确定子模型的显示面数，从而可以更细节的展示该子模型，提高展示效果；缩小展示子模型(采用第一距离显示子模型)时，采用数值较小的第一显示层级确定子模型的显示面数，可以降低非重要模型的面数和细节度，从而降低系统的处理数据量，减少资源消耗，提高渲染效率。
例如，可以提供显示面数确定单元，并通过该显示面数确定单元确定该子模型的显示面数；例如，也可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现该显示面数确定单元。
对于步骤S140，例如，对于多个子模型中的每个子模型，基于所确定的该子模型的显示面数，采用本领域的建模方法，确定该子模型的显示子模型。
例如，该显示子模型即为优化减面后的模型，例如，也是三维立体模型，采用该显示子模型在电子设备的显示界面上进行展示，可以在减少各个子模型的显示面数的同时，提高待显示对象的显示效果，减少了系统的数据处理量，降低了资源消耗。
例如，可以提供显示子模型确定单元，并通过该显示子模型确定单元确定该子模型的显示子模型；例如，也可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具 有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现该显示子模型确定单元。
图3为本公开至少一实施例提供的另一种显示处理方法的流程图。如图3所示，该显示处理方法还包括步骤S150-步骤S180。
步骤S150：保留该子模型的与基础模型的纹理贴图信息一致的子纹理贴图信息。
例如，对于多个子模型中的每个子模型，该子模型包括多个子纹理贴图信息UV0、UV1、UV2……。例如，该子模型的纹理包括该子模型的颜色和亮度等信息，子纹理贴图信息包括子模型中的每个点的纹理在图片上的坐标，从而可以根据该坐标将图片上各个点的纹理精确对应到三维模型的表面上，从而可以正确的显示该三维模型的纹理。
由于将该子模型(例如，一个六面体)的各个面展开至二维平面中时，展开方式有多种，例如，展开后六个面的序号排布方式可以是123456，也可以是612345，只要保证各个面的纹理贴图信息与该子模型在三维空间中的相对位置关系对应即可(即，面1的纹理贴图信息对应三维模型上的面1，面2的纹理贴图信息对应三维模型上的面2，……，面6的纹理贴图信息对应三维模型上的面6)，因此，不同的展开方式(及不同的序号排布方式)对应不同的纹理贴图坐标，因此，该子模型包括多个子纹理贴图信息。
例如，在子模型包括的多个子纹理贴图信息UV0、UV1、UV2……中，子纹理贴图信息UV0与基础模型中的纹理贴图信息一致，其余的可能不一致，因此，保留该子模型的与基础模型的纹理贴图信息一致的子纹理贴图信息UV0以用于后续显示子模型的显示。
步骤S160：删除除保留的子纹理贴图信息之外的其他子纹理贴图信息。
例如，在一些示例中，由于在大多数情况下，创建显示子模型时并不需要多套子纹理贴图信息，仅需要一套与基础模型一致的纹理贴图信息即可，因此删除除保留的子纹理贴图信息之外的其他子纹理贴图信息，以减少文件的数据量，提高系统的响应速度。
步骤S170：对于多个子模型中的每个子模型，修改该子模型的名称，以与该子模型对应的基础模型的名称保持一致。
例如，图像渲染引擎在将基础模型拆分成为多个子模型进行编辑时，可 能会改变各个子模型的名称，这样会导致将多个子模型导出引擎后其他软件再进行后续操作时名称将无法对应，从而无法进行相应的操作。为了避免出现这种情况，对于多个子模型中的每个子模型，修改该子模型的名称，以与该子模型对应的基础模型的名称保持一致。
例如，假设器官肝脏为其中一个子模型，其在基础模型中的名称是肝脏，那么该子模型的名称也应该是肝脏。
步骤S180：利用多个子模型的显示子模型，来显示待显示对象。
例如，该显示子模型即为优化减面后的模型，在电子设备的显示界面上展示该显示子模型，可以在减少各个子模型的显示面数的同时，提高待显示对象的显示效果，减少了系统的数据处理量，降低了资源消耗。
例如，各个子模型的显示处理方法(例如，上述步骤S120-S170)可以并行进行，从而可以提高该显示处理方法的速度，减少耗时，提高显示处理效率。
图4为本公开至少一实施例提供的一种显示待显示对象的方法的流程图。也就是说，图4为图3中所示的步骤S180的一些示例的流程图。例如，在图4所示的示例中，该确定方法包括步骤S181至步骤S183。下面，结合图4对本公开至少一实施例提供的显示待显示对象的方法进行详细地介绍。
步骤S181：将多个子模型的显示子模型导入三维软件。
例如，在步骤S170中，获取最终的显示子模型后，将该显示子模型输出至三维软件中进行合并。例如，该三维软件可以包括3ds max、Maya、Cinema 4D、zbrush等。
步骤S182：在三维软件中合并多个子模型的显示子模型以获得基础模型的显示模型。
例如，在三维软件中合并多个元素对应的子模型的显示子模型以获得基础模型的显示模型，例如，获得器官肝脏的显示模型，或者获得人体的显示模型。例如，该显示模型也是三维立体模型。
例如，可以通过本领域的合并方法合并各个子模型的显示子模型，本公开的实施例对此不作限制，在此不再赘述。
例如，该基础模型的面数很多，该显示模型为优化减面后的待显示对象的三维人体模型，其显示面数远少于基础模型的面数，从而可以减少系统的 数据处理量，降低资源消耗。
步骤S183：显示显示模型以显示待显示对象。
例如，在电子设备的显示界面上展示该显示模型，可以在减少各个子模型的显示面数的同时，提高待显示对象的显示效果，减少了系统的数据处理量，降低了资源消耗。
需要说明的是，在本公开的实施例中，本公开上述各个实施例提供的显示处理方法的流程可以包括更多或更少的操作，这些操作可以顺序执行或并行执行。虽然上文描述的显示处理方法的流程包括特定顺序出现的多个操作，但是应该清楚地了解，多个操作的顺序并不受限制。上文描述的显示处理方法可以执行一次，也可以按照预定条件执行多次。
本公开上述实施例提供的显示处理方法可以基于显示环境和显示细节层级确定各个子模型的显示面数，从而可以在减少各个子模型的显示面数的同时，增加各个子模型的可控数据，提高了待显示对象的显示效果，减少了系统的数据处理量，降低了资源消耗。
图2C为一种人体三维模型的原始模型(即，未减面的模型)的示意图；图2D为采用本公开至少一实施例提供显示处理方法对图2C所示的人体三维模型进行减面后获得的显示模型；图2E为人体的蝶骨的原始模型的示意图；图2F为采用本公开至少一实施例提供显示处理方法对图2E所示的蝶骨进行减面处理后的示意图。
如图2C所示，未减面的人体三维模型例如包括4916042个三角面，如图2D所示，减完面后的显示模型包括2800316个三角面，例如，对人体三维模型中的肌肉、骨骼和骨连接等部位均已进行减面，其余部分尚未进行上述显示处理(即，尚未进行减面)。如图2E所示，蝶骨的原始模型包括10189个三角面，如图2F所示，减面后蝶骨模型包括1527个三角面，约为基础模型的15％，基本达到减面极限。
由此可见，采用本公开至少一实施例提供的显示处理方法不仅可以实现最大限度的减面处理，以降低系统的数据处理量，同时还不影响显示模型的显示效果，提高了待显示对象的显示效果。
图5A为本公开至少一实施例提供的一种显示处理方法的系统流程图；图5B为图5A所示的显示处理方法的一种具体实现示例的系统流程图。下面 参考图5A和图5B对本公开至少一实施例提供的显示处理方法进行详细地介绍。
例如，如图5A和图5B所示，首先，将基础模型导入引擎，例如，该引擎可以是UE4引擎，在UE4引擎中将基础模型拆分为多个子模型，该多个子模型的名称发生改变，UV(子纹理贴图信息)的数量增加，将拆分的多个子模型导入根据UE4开发的插件中。例如，在该插件中设置控制子模型的显示面数的预设值，例如，设置第一显示层级LOD1和第二显示层级LOD2，增加LOD分级，例如，在采用第一距离显示该子模型时，采用第一显示层级确定该子模型的显示面数，在采用第二距离显示该子模型时，采用第二显示层级确定该子模型的显示面数，以降低子模型的显示面数，并基于该子模型的显示面数确定子模型的显示子模型，具体介绍可参考步骤S110-S130的相关描述，在此不再赘述。例如，在该插件中还设置各个子模型的名称和UV(纹理贴图信息)数量，例如，保留该子模型的与基础模型的纹理贴图信息一致的子纹理贴图信息，删除除保留的子纹理贴图信息之外的其他子纹理贴图信息，对于多个子模型中的每个子模型，修改该子模型的名称，以与该子模型对应的基础模型的名称保持一致，具体介绍可参考步骤S160-S170的相关描述，在此不再赘述。然后，输出各个子模型的显示子模型，并导入三维软件，在三维软件中合并多个子模型的显示子模型以获得基础模型的显示模型，具体介绍可参考步骤S181-S183的相关描述。最后，输出显示模型并在电子设备的显示界面显示该显示模型以显示待显示对象。
图6为本公开至少一实施例提供的一种显示处理装置的示意框图。例如，在图6所示的示例中，该显示处理装置100包括第一获取单元110、第二获取单元120、面数确定单元130和显示子模型确定单元140。例如，这些单元可以通过硬件(例如电路)模块或软件模块等实现，以下是实施例与此相同，不再赘述。例如，可以通过中央处理单元(CPU)、图像处理器(GPU)、张量处理器(TPU)、现场可编程逻辑门阵列(FPGA)或者具有数据处理能力和/或指令执行能力的其它形式的处理单元以及相应计算机指令来实现这些单元。
第一获取单元110，配置为获取待显示对象的基础模型的多个子模型。例如，每个子模型包括多个面。例如，该第一获取单元110可以实现步骤S110， 其具体实现方法可以参考步骤S110的相关描述，在此不再赘述。
第二获取单元120配置获取待显示对象的显示环境参数。例如，该第二获取单元120可以实现步骤S120，其具体实现方法可以参考步骤S120的相关描述，在此不再赘述。
