Polygon Modeling
ZModeler
While ZBrush is best known for organic sculpting, it's hard surface capabilities should not be underestimated. The ZModeler system is designed specifically for low poly modeling with easily accessed and highly intuitive controls for creating holes, adding edge loops, extruding polygons and much more.
Deformers
Gizmo 3D gives you easy controls for the 27 deformers in ZBrush. It’s functions allow you to interactively bend, stretch, flatten, twist, slice, taper and much more. The Gizmo 3D Deformers give you a sleek workflow that allows for easy switching from one deformer to another.
Each deformer has a unique feature set to allow quick shape alterations that would not be possible through brush strokes. One unique deformer, Project Primitive, gives the capability to use multiple primitives to reshape a mesh, cut into a surface, build up from another mesh and so much more. Not only does Project Primitive offer a new, unique way to blend multiple pieces of geometry together it also empowers you to take something as simple as a sphere and turn it into a rocket ship, automobile, plane, human bust and much more.
Dynamic Subdivision
The Dynamic Subdivision system allows you to apply dynamic smoothing to your models without actually dividing the polygons. This feature is mainly designed to work in association with the ZModeler brush and low polygonal models.
Dynamic Subdivision mode is used to represent the result of smoothing your base mesh, letting you see what the divided model would look like even while you actually edit and sculpt the lower resolution mesh.
While working with Dynamic Subdivision active, you see the higher resolution surface while your brushes operate on the lower resolution base mesh.
Dynamic Subdivision is applied to the model in real-time. While the function is active, any changes in the base mesh topology will show an immediate result in the displayed smooth surface.
