But even if no posing or animation is required, the semi-random polygon structure often causes visible surface irregularities, especially if you sculpt with triangular polygons, like when using Blender 3D's Dyntopo sculpting. This quad-polygon structuring and restructuring can be time-consuming and sometimes frustrating, and often takes away the spontaneous part of 3D model creation.Ī downside of freeform digital sculpting is that it usually results in a messy polygon structure, making the 3D model unsuitable for deformation, such as for posing or animating a character. The workflow of digital sculpting feels very much like traditional sculpting, adding daubs of digital clay and dynamically shaping them into a sculpture, while polygon subdivision modeling requires careful construction and adjustment of a quadrangular polygon cage in order to successfully subdivide it to a smooth result. I love the technique of freeform digital sculpting, as an alternative to polygon subdivision modeling. We bring to you in the following section some of his work. Metin Seven a 3D designer, illustrator and animator has done a comparative study on the two best 3D auto-retopology algorithms available today - 3D Coat's Autopo and ZBrush's ZRemesher.
