在Python的3D图像处理中,通常用numpy array来进行非常方便的计算或者转化,这里记录一下numpy数据的VTK可视化基本流程,包括面绘制(Surfase Rendering)和体绘制(Volume Rendering)。除去数据格式转化,面绘制和体绘制在C++中也是类似的处理方法。 numpy数据转成vtkImageData 首先得把numpy

To make things worse, if you’re aIPython Notebookfanatic such as myself, you’re in for a let-down.VTKdoesn’t come with an HTML output option that would allow you to directly embed the rendering results into a notebook, or any other web-application for that matter. Obviously, being...
