如何在Django中使用pythonOCC将3D对象呈现为HTML文件？
我有一个Django应用程序，我在其中使用pythonOCC包。我必须在模板中显示3D.stl、.stp、.igs文件。通常，当我调用render（）函数时，以下输出会出现在我的vscode控制台上，因为由pythonocc而不是django创建的flask应用程序开始在localhost中运行，所以我的index.html永远不会被呈现。但是，我需要在Django模板中显示文件。这就是为什么我扩展了下面的方法 我的自定义渲染器类：如何在Django中使用pythonOCC将3D对象呈现为HTML文件？,python,django,django-templates,pythonocc,Python,Django,Django Templates,Pythonocc,我有一个Django应用程序，我在其中使用pythonOCC包。我必须在模板中显示3D.stl、.stp、.igs文件。通常，当我调用render（）函数时，以下输出会出现在我的vscode控制台上，因为由pythonocc而不是django创建的flask应用程序开始在localhost中运行，所以我的index.html永远不会被呈现。但是，我需要在Django模板中显示文件。这就是为什么我扩展了下面的方法 我的自定义渲染器类： class CustomX3DomRenderer(x3dom
