将 2D 转换为 3D（带尺寸）
在 C# 中，如何将一张 2D 图像转换为具有尺寸的 3D 图像？像这样 http://thorrdynamics.com/images/cam_print.jpg 在 3D 模型的左侧在右侧。 有可能吗？感谢您的帮助
in c# how to convert one 2D image to 3D image with dimension? Like this http://thorrdynamics.com/images/cam_print.jpg in left side to 3D model in right side.
Its possible? Thx for any help

一般来说，没有。您无法拍摄 2D 图像、“添加尺寸”并显示结果对象的投影。仅凭图像，您没有足够的信息来说明该对象的实际外观。为了显示 3D 对象的投影，您需要知道组成该对象的所有顶点（例如，长方体角的
[x,y,z]坐标）和信息这说明了这些顶点如何相互连接（边）。有了这些信息，您就可以从任何角度创建对象的投影，尽管这样做并不简单。查看线框模型和3D 建模 了解更多信息。
In general, no. You can't take a 2D image, "add a dimension," and display a projection of the resulting object. With just an image, you don't have enough information to say what the object actually looks like. In order to display a projection of a 3D object, you need to know all the vertices that make up the object (the
[x,y,z]coordinates of a box's corners, for example) and information that says how those vertices are connected to each other (the edges). With that information, you can create a projection of the object from any angle, although doing so is non-trivial.Look into Wireframe models and 3D modeling for more information.
