Hello friends,
I have this mesh from a 3d scan (pic 1)... but when I transform to a body (pic 2), the body has these triangles. I need this smooth object!
Does anyone know how I can do this?
The imported mesh is triangulated. What you see in the viewport is a smoothed view, but that is really just a shading algorithm fooling your eyes into believing it is smooth. The actual geometry, however, is not a smooth surface, it is a triangulated mesh.
When converted into a BRep directly it will be very faceted.
I understand your question 😉
I made the youtube tutorial below about 2 years ago to address such questions:
There are many stumbling blocks and caveats for people like you that aare new to the subject matter. Good lick with your efforts.!
You can somewhat reduce the number of faces by lowering the number on Instant Meshes, but lowering the number of quad-faces too far will obviously result in a loss of detail.
Ultimately the quad faces are converted into a T-Spine and from there into a number of NURBS surfaces. The conversion from T-Splines into NURBS surfaces will automatically generate a number of NURBS patches and the number depends on curvature and topology of the underlying geometry.
I don't think mathematically it is possible to have such a shape represented by a single NURBS surface. I am not sure why you'd need that either.
Can you explain what you intend to do with the result ?
