Hello, am quite new on 3d slicer would like to know if numerical data’s can be transformed to images on this platform or something similar. Please i will highly appreciate recommendations of tutorial materials

What’s the numerical data’s? like OpenSCAD build a 3d model by code?

Yes, it would be good to know what numerical data you have. Nevertheless, it should be easy to convert most data structures (arrays, meshes, contours, etc.) to images.

For example, you can directly convert a numpy array to an image node using slicer.util.updateVolumeFromArray ([http://slicer.readthedocs.io/en/latest/developer\_guide/slicer.html#slicer.util.updateVolumeFromArray](http://slicer.readthedocs.io/en/latest/developer_guide/slicer.html#slicer.util.updateVolumeFromArray)).
