本文主要是介绍【autodesk】浏览器中渲染rvt模型,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
使用Forge完成渲染
Forge是什么 为什么能够渲染出来rvt模型
- Forge是由Autodesk开发的一套云端开发平台和工具集。
- 在Forge平台中,有一个名为"Model Derivative"的服务,它可以将包括RVT(Revit)在内的多种BIM(Building Information Modeling)文件格式转换为可在Web上浏览和渲染的格式。
- 具体来说,"Model Derivative"服务可以将RVT(Revit)文件转换为SVF(Scalable Vector Graphics)格式。
- SVF是一种基于Web的轻量级3D模型表示格式,可以实现高性能的3D模型渲染和交互。通过将RVT文件转换为SVF格式,可以在Web端使用Forge提供的Viewer组件加载和展示RVT模型
Forge与Autodesk的关系
- Autodesk是一家设计软件公司,Forge可以视为Autodesk的云端扩展
渲染步骤:
首先要注册autodesk平台,并创建项目 获取自己的client_id与client_secret
官网地址:Autodesk Platform Services (formerly Forge)
如下图:
配置postman环境
下面我们演示通过postman上传模型到Forge云端,然后配置Forge的js渲染出来

}
client_secret与client_id记住改成自己的,然后就开始用postman请求上传了
获取access token
https://developer.api.autodesk.com/authentication/v1/authenticate
是用于获取 Autodesk API 的访问令牌(access token)的认证
请求中包含必要的认证信息
- 客户端 ID(client_id)
- 客户端密钥(client_secret)
grant_type
:授权类型,通常为 "client_credentials"(客户端凭据模式)scope
:请求的权限范围,用空格分隔多个权限(如 "data:read data:write")- expires_in:设置合适的过期时间,单位毫秒
响应结果:

https://developer.api.autodesk.com/oss/v2/buckets
请求中包含必要的认证信息:
- Authorization:Authorization: Bearer {{access_token}}
bucketKey
:存储桶的唯一标识符,它必须是全局唯一的。可以使用小写字母、数字、连字符-
和下划线_
来命名。长度应在3到128个字符之间。policyKey
:存储桶的访问策略。默认为transient
,表示存储桶中的对象在30天后过期;persistent,表示
永久保存
响应结果:
查看bucket是否创建成功
https://developer.api.autodesk.com/oss/v2/buckets
请求中包含必要的认证信息:
- Authorization:Authorization: Bearer {{access_token}}
请求可选的参数信息:
limit
:指定要返回的存储桶数量的限制。例如,返回最多 10 个存储桶,默认为 10
响应结果:
往bucket里放置object模型
https://developer.api.autodesk.com/oss/v2/buckets/{bucketKey}/objects/{objectName}
请求中包含必要的认证信息:
- Authorization:Authorization: Bearer {{access_token}}
- 选择需要放置的rvt模型
- objectName:每个文件在存储桶中都有一个唯一的标识符
响应结果:
检查对象模型是否成功上传到 Autodesk Forge 存储桶(bucket)中
https://developer.api.autodesk.com/oss/v2/buckets/{{bucketKey}}/objects
请求中包含必要的认证信息:
- Authorization:Authorization: Bearer {{access_token}}
- bucketKey:查询的存储桶的实际标识符
响应结果:
将模型在云端转换成SVF格式
https://developer.api.autodesk.com/modelderivative/v2/designdata/job
请求中包含必要的认证信息:
- Authorization:Authorization: Bearer {{access_token}}
input
:指定要转换的对象的 URN(Uniform Resource Name)。将 object_id 的 URN 作为输入。output
:指定要生成的输出格式和文件类型。在这里,你可以指定 SVF 格式作为输出。例如,{"formats": [{"type": "svf", "views": ["2d", "3d"]}]}
备注:input中的
urn是 objectId转化为Base64格式
响应结果:
检查模型是否转化完成
https://developer.api.autodesk.com/modelderivative/v2/designdata/{base64_urn}/manifest
请求中包含必要的认证信息:
- Authorization:Authorization: Bearer {{access_token}}
- base64_urn:经过 Base64 编码的 URN
响应结果:
图一表示进度,图二代表成功
浏览器渲染:
html渲染模板 将accessToken与documentId替换掉就行
