How can you create a 3D model using NURBS?

1 Creating Curves

The first step in creating a 3D model using NURBS is to create curves that define the outline of your object. Curves are composed of control points that determine the direction and shape of the curve. You can create curves using different tools, such as the CV Curve Tool, the EP Curve Tool, or the Pencil Curve Tool, depending on the level of control and precision you need. You can also modify the curves by moving, scaling, or rotating the control points, or by changing the curve degree, which affects the smoothness of the curve.

2 Creating Surfaces

The next step is to create surfaces that fill the gaps between the curves. Surfaces are composed of patches that are defined by four boundary curves. You can create surfaces using different tools, such as the Loft Tool, the Revolve Tool, or the Extrude Tool, depending on the shape and orientation of your curves. You can also modify the surfaces by adjusting the surface degree, which affects the smoothness of the surface, or by adding or deleting isoparms, which are subdivisions of the surface.

3 Editing Surfaces

The third step is to edit the surfaces to refine the shape and appearance of your object. You can edit the surfaces by manipulating the control points, or by using various tools, such as the Insert Knot Tool, the Detach Surface Tool, or the Trim Tool, to modify the topology and boundaries of the surface. You can also use the Stitch Tool or the Attach Surface Tool to connect or merge adjacent surfaces, or use the Fillet Tool or the Blend Tool to create smooth transitions between surfaces.

4 Converting to Polygons

The final step is to convert your NURBS model to polygons, which are the standard format for rendering and animating 3D models. You can convert your NURBS model to polygons using the Convert NURBS to Polygons option in the Modify menu. You can also adjust the conversion settings, such as the tessellation method, the number of polygons, or the texture mapping, to optimize the quality and performance of your polygonal model. Once you have converted your NURBS model to polygons, you can apply materials, textures, lights, and other effects to enhance your 3D model.
