3D models can be generated from continuous images.
Continuous images can be get through industrial X-ray, medical CT etc.
Medical cross section data are defined as DICOM and these images can be used to generate 3D models.
The program called VoxeFromImages can generate 3D models(STL) from continuous images.

The next image is a rendering with NfDesign.
After drawing images files from public announced DICOM,
the gray level of the images are controlled, then VoxelFrom Images has generated STL.
NfDesign imported the file and deleted unnecessary objects, and rendering is put in practice.

The next is also a STL. The interval of the images is broad and the generated object has stairs.

There is a command, POLISH in NfDesign. The next imge is a result of the command.

The next is also a STL after control of gray scale of images.

The next is also a STL from the same DICOM as previous, but the gray scale are different.

The next is from industrial images.

The next is also from industrial images.

Our program called NfDesignCS can generate images from STL.
The next two images are reconstructed STLs from STLs.
