其中，数据中心的平面图中的墙体的横截面即为基础3D模型生成时候需要的拉伸面，宽度依照图纸的设定，在进行3D拉伸操作的时候，需要给拉伸一个高度。例如，将墙体高度默认值设为3米。
为了使“通过平面图中基础元素的坐标，使用凸包算法计算出外轮廓多边形，作为楼层的地面”过程更清楚，对于底面的计算方式举例如下：
将平面图中各个基础元素坐标制作成点集。例如矩形元素代表是4个点，曲线划分成10～20个线段，故可能为11～21个点，将所有这些元素点组合成点集。在点集中选取y坐标最小的一点H，当作基点。如果存在多个点的y坐标都为最小值，则选取x坐标最小的一点。坐标相同的点应排除。然后按照其它各点和基点构成的向量与x轴的夹角进行排序，夹角由大至小进行顺时针扫描，反之则进行逆时针扫描。实现中无需求得夹角，只需根据余弦定理求出向量夹角的余弦值即可。以图3为例，基点为H，根据夹角由小至大排序后依次为K，C，D，L，F，G，E，I，B，A，J；之后进行逆时针扫描。由于夹角最小，所 以线段<H,K>一定在凸包上，接着加入C。假设线段<K,C>也在凸包上，就H，K，C三点而言，它们的凸包就是由此三点所组成；但是接下来加入D时会发现，线段<K,D>才会在凸包上，所以将线段<K,C>排除，C点不可能是凸包。按照上述步骤进行扫描，直到点集中所有的点都遍历完成，即得到凸包HKDGBJ。
另外，平面图可为CAD图纸；可选的，在根据数据中心的平面图中的几何元素获取数据中心的基础3D模型之前，对数据中心的CAD图纸进行简化，包括：将数据中心的楼层区域外的内容移除；将数据中心的楼层区域内除墙体建筑线条外的其余内容移除。即，数据中心的楼层区域外无内容，楼层区域内仅保留墙体建筑线条，将辅助线和说明信息等内容均移除，使得图纸画面整洁，提高建模过程中的识别精确度。
在步骤102中，根据平面图中的标记，在基础3D模型中标记的位置填充标记对应的模型，生成数据中心的3D模型；标记至少包括设施标记，设施标记与预置模型库中的模型一一对应。
在一个例子中，标记包括设施标记，设施标记包括设施的位置和方向；根据平面图中的标记，在基础3D模型中标记的位置填充标记对应的模型，包括：根据平面图中的设施标记，在基础3D模型中设施标记的位置和方向，填充设施标记对应的预置模型库中的设施模型。
设施模型包括：数据中心的各种微模块机柜、数据中心的电池柜、配电柜、空调柜、各类传感器等，例如设施标记a针对楼层内的配电柜a，则在图中的设施标记a相应的位置处，填充配电柜a的设施模型；并根据设施标记a中的方向，保持配电柜a相对方向和相对大小的一致性。使得3D模型更完整，展示时能够向用户更直观的结构内容。
对于通过平面图纸获取3D模型，业界传统的方式为技术人员根据平面图纸进行二次构建，需要大量的人力投入，并且效率较低。本申请的实施方式提供一种设备由平面图纸自主生成3D模型的实施过程，包括通过几何元素得到基础3D模型，通过设施标记与预置模型库中模型的对应关系，获取到与平面图中的标记对应的模型，并将获取到的模型填充到基础3D模型中，通过设施标记对基础3D模型进行优化处理等得到3D模型。无需技术人员根据平面图纸进行二次构建，通过建模得到3D模型，可以有效减少获取3D模型过程中的人 力投入，提高了开发效率。
本申请的第二实施方式涉及一种数据中心3D建模方法，如图4所示。
步骤201，根据数据中心的工程CAD图获取SVG平面图；根据工程CAD图，为SVG平面图添加标记，得到的标记后的SVG平面图；
步骤202，根据数据中心的SVG平面图中的几何元素，获取数据中心的基础3D模型，基础3D模型包括墙体及地面；
步骤203，根据SVG平面图中的标记，在基础3D模型中标记的位置填充标记对应的模型，生成数据中心的3D模型；其中，标记包括特定标记和设施标记，特定标记用于标识基础3D模型的装饰模型，设施标记与预置模型库中的设施模型一一对应。
其中步骤202与第一实施例中大致相同，为避免重复，不再赘述；不同之处在于步骤201及步骤203，以下对于步骤201及步骤203的实现细节进行说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
在步骤201中，根据数据中心的工程CAD图获取SVG平面图；根据工程CAD图，为SVG平面图添加标记，得到的标记后的SVG平面图。可选的，将工程CAD图转化为CSV坐标文件格式，之后将CSV坐标文件格式转化为SVG平面图，从而由数据中心的工程CAD图获取SVG平面图。标记包括：特定标记和/或设施标记。其中，在SVG平面图上打上依照工程CAD图得到的类型标记。在一个例子中，标记只含类型不需要尺寸数据，SVG平面图自主包含尺寸信息。加标记的方式需要按照程序中预设的方法来设置，程序会读取这些标记。一般在建好模型后会由开发工程师将3D模型导入三维运行环境展示三维模型内容，而往往需要有三维展示的地方，一般都需要二维信息的展示，工程CAD图专业性较强，不适合非技术人员观看，本实施例首先将其转化为SVG平面图，除了得到数据中心的3D模型外，可二次复用导入二维展示页面，使得二维信息展示更方便且直观，同时SVG平面图较CAD图减少了辅助线条等对于展示二维信息多余的内容，提高用户观看体验。
在一个例子中，对SVG平面图添加标记，是接收用户指令，在SVG的XML文档中增添特定标记和/或设施标记的标记属性。例如：
标记前：<rect x＝0 y＝0 width＝600 height＝1200>
标记后：<rect x＝0 y＝0 width＝600 height＝1200 data-height＝”2150”data-type＝”rack”>
其中data-type＝”rack”机架类型data-height＝”2150”机架高度值。
另外，根据数据中心的工程CAD图获取SVG平面图，包括；对数据中心的工程CAD图进行简化；根据简化后的工程CAD图获取SVG平面图。由于工程CAD图中为了进行建筑设计，除建筑主体部分外，还会存在大量辅助内容，包括设计线条及说明信息，将辅助内容删除，能够降低SVG平面图生成过程中的错误率，提高SVG平面图的转化效率。
其中，对数据中心的CAD图纸进行简化，例如：将数据中心的楼层区域外的内容移除；将数据中心的楼层区域内除墙体建筑线条外的其余内容移除，即，数据中心的的楼层区域外无内容，楼层区域内仅保留墙体建筑线条，将辅助线和说明信息等内容均移除。因此，将工程CAD简化后转化为SVG平面图的过程，例如：先移除多余线条、说明等辅助信息，并将移除后的工程CAD图导出为CSV文件，读取CSV文件，生成SVG平面图。
在步骤203中，根据SVG平面图中的标记，在基础3D模型中标记的位置填充标记对应的模型，生成数据中心的3D模型；其中，标记包括特定标记和设施标记，特定标记用于标识基础3D模型的装饰模型，设施标记与预置模型库中的设施模型一一对应。
在一个例子中，在得到基础3D模型后，除了根据模型库中设施标记对应的设施模型填充对应位置外，还包括：根据特定标记，对基础3D模型的不同类型的墙体填充对应的纹理模型；不同类型的墙体包括：内墙和外墙；对特定标记标识的柱子填充柱子纹理模型；对特定标记标识的门的位置做布尔减操作，在布尔减操作后的空位填充门模型。即，在墙体和地面组成及基础3D模型上，将外墙、内墙、柱子、门等，做细致化的效果处理，使得最终的数据中心的3D模型能够更完整的展现平面图中的二维信息，并提高用户的观看体验。
本实施方式相对于第一实施方式，将工程CAD图转化为SVG平面图进行处理，使得在进行模型展示的同时，完成数据中心结构的二维展示；在执行模型填充的过程中，根据特定标记将建筑的墙、柱子、门等加入特定的装饰信息，使得数据中心的3D模型能够更完整且具体展示平面图中的结构内容，提升用 户观看体验。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
此外，本领域技术人员可以理解，第一实施方式与第二实施方式所涉及的技术实现步骤不冲突，为了优化实施过程中的技术效果，可以将第一实施方式与第二实施方式中步骤结合使用。
