Only then should you construct the NURBS surface.<div class="embed-placeholder" data-type="youtube" data-id="pDEyX0lhAZo"></div><figcaption>NURBS part 2: Creating surfaces from curves</figcaption><h2>What is the Difference Between Polygonal and NURBS Modeling?</h2>You’ll meet polygonal and NURBS modeling in any <a href="https://3dstudio.co/3d-modeling-services" rel="nofollow" dir="ltr">3D modeling services</a> since they are quite similar. Still, some differences tell them apart. Since you’ve probably already gone through polygonal modeling, we have to cover these differences to show the contrast.&nbsp;<h3>Modeling Workflow</h3>Creating objects in polygonal modeling is easy because it is usually an N-gon used to manipulate and change the mesh.&nbsp;&nbsp;In NURBS, on the contrary, objects are always 4-sided which sets some limitations in the modeling workflow.What is more, NURBS objects are always separated and hard to attach, though you won’t even see the seams between them.&nbsp;Pro tip: convert a NURBS object into a <a href="http://3dstudio.co/polygon-mesh" dir="ltr">polygon mesh</a> in case you want to animate it, so the joints don’t come apart.<figure><img width="745" height="745" src="https://3dstudio.co/wp-content/uploads/2022/01/nurbs-modeling-tool-blender.jpg" alt="nurbs modeling tool blender" srcset="https://3dstudio.co/wp-content/uploads/2022/01/nurbs-modeling-tool-blender.jpg 1000w, https://3dstudio.co/wp-content/uploads/2022/01/nurbs-modeling-tool-blender-300x169.jpg 300w, https://3dstudio.co/wp-content/uploads/2022/01/nurbs-modeling-tool-blender-768x432.jpg 768w, https://3dstudio.co/wp-content/uploads/2022/01/nurbs-modeling-tool-blender-18x10.jpg 18w"><figcaption dir="ltr">(source <a href="https://www.youtube.com/watch?v=cEe57tKwUIA&amp;t=12s&amp;ab_channel=JoshGambrell" rel="noreferrer noopener nofollow" dir="ltr">YouTube</a>)</figcaption></figure><h3>File Size</h3>Oftentimes when you transfer polygonal models to different 3D modeling software and programs, meshes get distorted for multiple reasons.&nbsp;However, you may not face the same issue with NURBS modeling since the files that contain mathematical points are easily read.

Correspondingly, it calculates these polygons. However, it calculates the lines between the points, so it can’t make a smooth curve.Note: You can use smoothing groups and increase the number of polygons to create the perception of the smoother curves.NURBS, on the other hand, uses complex mathematics to calculate the splines between points that comprise a mesh.While it allows higher accuracy than in polygonal modeling, NURBS calculations are harder to process. No wonder you’ll never see NURBS in video games.
