3D Scan vs 3D Modeling

Can 3d scanning replace 3d modeling entirely(for objects like assets, furniture, etc.)? What are cons and pros for each approach?

Until a 3D scan can report information about what a point is, and allow the user to collect points as an object (e.g. all points belonging to a chair) I doubt it. One also has to question how demolition/new works are captured in existing scan data.

Most companies doing scan2bim are manually modelling a BIM model over the scan still - lots of smoke and mirrors being used.

Was wondering if we could use the same approach Quixel is using for individual objects like furniture. A round table with hundreds of camera around it (like a dome) that shoot images 50 times / second in 4k to 8k resolution and then, suing stitching software assemble them together to regenerate the accurate mesh. Do you think its feasible?

It is possible, although some programs don’t really handle mesh or textured mesh very well. It would be worth looking into RPC/proxy based rendering workflows for such programs as Revit or ArchiCAD. Enscape has achieved an outcome along these lines with their asset library.

There are quite a few tool sets to creat an RPC for 3ds Max. Do you know of any for Revit?

Great. Will take a look and maybe purchase and try it to see how it works
