Introduction
基于模型对象的凸包运算。对该资源发送POST请求，则可以Creates a凸包结果资源。
Supported methods:
- GET：Returns a form for the POST request.
- POST：Creates a凸包结果资源。
- HEAD：检查convexhullresource exists, or if there is permission to accessconvexhull资源。
Supported output formats:RJSON、JSON、HTML、XML。

HTTP Request Methods
Perform an HTTP request on the following URI, using the rjson output format as an example. Here, supermapiserver is the server name.
http://supermapiserver:8090/iserver/services/spatialAnalysis-BIM/restjsr/spatialanalyst/geometry/3d/convexhull.rjson
GET 请求
Returns a form for the POST request.
POST 请求
Creates a凸包结果资源。
Request parameters
Parameters in the request body are as follows:
| Field | Type | Definition |
| model | GeoModel3D | [Required parameter]源模型对象，即凸包计算中被操作的模型对象 |
| resultSetting | GeometrySpatialAnalystResultSetting | 凸包计算结果设置，即模型对象凸包结果设置 |
Response structure
Normal response code(s): 201. The response parameters are as follows:
| Name | Type | Description |
| postResultType | postResultType | POST 请求的结果类型，枚举说明 POST 请求对目标资源的影响，即处理结果是什么样的。 |
| newResourceID | String | 分析结果资源的 ID。 |
| succeed | boolean | 分析是否成功。 |
| newResourceLocation | String | 创建的新资源的 URI。 |
Example of response
对geometryConvexHullResults资源：http://supermapiserver:8090/iserver/services/spatialAnalysis-BIM2/restjsr/spatialanalyst/geometry/3d/convexhull.rjson，执行 POST 请求，请求参数如下：
{
"model":{"type":"GEOMODEL3D", "modelUrl":"http://supermapiserver:8090/SampleData/AirPlane.s3m", "position":{"x":120.2, "y":40.2, "z":10}}
}
The returned resource description in rjson format is shown below:
{
"postResultType":"CreateChild",
"newResourceID":"ca097"
,"succeed":true,
"newResourceLocation":"http://supermapiserver:8090/iserver/services/spatialAnalysis-BIM/restjsr/spatialanalyst/geometry/3d/convexhull/ca097"
}
HEAD 请求
Returns the same HTTP response headers as a GET request, but without the response body. This allows retrieving meta-information from the response headers without transporting the entire content. The meta-information includes the media type,字符编码，压缩编码，实体内容长度等。
A HEAD request can be used to check ifconvexhull 资源是否存在，或者客户端是否有权限访问convexhull资源。通过对加.<format>的 URI 执行 HEAD 请求，还可以快速判断convexhull 资源是否支持<format>格式的表述。
