Curved cylinder

Is there a algorithm that can convert 3d polyline to a triangle mesh as shown above?

Hello!

Unfortunately right now we don't have such functionality, We will try to work on it later.
Thanks for suggestion.

Thanks a lot.

We have

/// Offsets polyline by converting it to voxels and building iso-surface
/// do offset in all directions
/// so result mesh is always closed
[[nodiscard]] MRMESH_API Expected<Mesh, std::string> offsetPolyline( const Polyline3& polyline, float offset, const OffsetParameters& params = {} );

it is not exactly your case, but it prouce simular output.

Hello!
We have just added

MeshLib/source/MRMesh/MRMovementBuildBody.h

Lines 25 to 28 in 7e840df

	/// makes mesh by moving `body` along `trajectory`
	/// if allowRotation rotate it in corners
	[[nodiscard]] MRMESH_API Mesh makeMovementBuildBody( const Contours3f& body, const Contours3f& trajectory,
	const MovementBuildBodyParams& params = {} );

Thanks a lot

If my curves are curved, how do I better avoid intersections?

[Grantim]

You can use Offset tool to fix it (by casting to voxels and back)

MeshLib/source/MRMesh/MROffset.h

Lines 59 to 61 in 5bb227d

	/// Offsets mesh by converting it to voxels and back
	/// so result mesh is always closed
	[[nodiscard]] MRMESH_API Expected<Mesh, std::string> offsetMesh( const MeshPart& mp, float offset, const OffsetParameters& params = {} );

Thanks

Hello,I find that solidworks have this function-swept surface.

Will this special algorithm be added later?

[Grantim]

Thanks for pointing on it, we will try to improve our algorithm later!
