What kind of file format the CT machine produce? DICOM? What's the spatial resolution of the model? How big was the file for this component? Could you make the file available? Are they using webgl to display the volume in 3D?
- kens 4y agoThe system is web-based so I don't know about the underlying file format. They've downloaded files to a 3-D printer so it's something usable. The spatial resolution depends on the size of the object (which determines how close it is to the sensor). In one scan we saw the bond wires inside a transistor in a unit, so the resolution can be very good. For a large, dense metal object the resolution is lower. This scan is online at: https://app.lumafield.com/project/afa60fd5-308d-41da-a0c6-14294af54338 https://app.lumafield.com/project/afa60fd5-308d-41da-a0c6-14... You can manipulate the scan yourself after creating an account.
- skywal_l 4y agoSo apparently the volume is loaded in 3 chunks 95MB (285M). Looking at the code they are indeed using WebGL (through Three.js) for the raytracing. I don't think it's a DICOM format, at least not on the frontend side as I don't see the usual DICOM fields used in 3D rendering in the code. They have multiple versions of React bundled, I don't know what's the story about that. Anyway, thanks for the link, nice piece of technology.
- kens 4y agoI asked Lumafield. They say that the can export mesh files for 3D printing, but they don't support DICOM files.
