NURBS 3D Generation

What is NURBS?

NURBS (Non-Uniform Rational B-Splines) is a mathematical framework used in computer graphics for generating and representing smooth curves and surfaces

NURBS surfaces are widely used in CAD software for designing complex shapes and surfaces

Unlike a polygonal mesh, a NURBS surface has infinite resolution and can be manipulated by its control points to create any complex shape

How do I create a NURBS model?

You can convert any image on SuperCraft to a high quality 3D model by clicking on the Open 3D button.

Once generated, you can use the brush tool or the grid tool to select a surface formed by a continuous rectangular grid of faces

Note that the selection has to form a rectangular grid for the conversion to work.

Once you have selected the grid, click on the to NURBS button to generate the NURBS surface

This will create the NURBS surface and render control points on the surface that you can manipulate to further refine the shape

The model can be exported as a .3dm file, that will preserve the NURBS surface and control points in Rhino, SolidWorks or other CAD software.

It can also be exported as a .obj file, which will convert the NURBS surface to a polygon mesh. The control points will not be preserved in this case.

Can I export the model with textures?

Yes you can export the original 3D model without any edits, with textures and materials applied to it in .glb format

Note: currently the grid selection experience is not the best and we are working hard to make it better
