DynaMesh, NanoMesh, and ZRemesher

Learning Objectives

After completing this chapter, you will be able to:

• Work with DynaMesh

• Work with ZRemesher

• Create different models using the DynaMesh tool

INtroduction

In ZBrush, you can create various types of models using different techniques. The models created in ZBrush have extremely high level of details that cannot be achieved in other modeling software applications. ZBrush uses brush based approach to add details to a model. Different studios such as Luma Pictures, Id Software, and Meteor Studio have used ZBrush for character creation. For instance, the characters Davy Jones in the movie Pirates of the Caribbean and Na'vi in the movie Avatar were created with ZBrush. In this chapter, you will learn about Dynamesh and ZRemesher that help you in creating high detail models.

DynaMesh

DynaMesh modeling is similar to clay modeling. In clay modeling, you can expand the existing lump of clay by either stretching it or by adding new lumps to it. After stretching the clay, the actual consistency of the clay remains the same. DynaMesh uses the same approach for modeling. After converting any mesh into DynaMesh, the uniform polygon distribution of the mesh is maintained, irrespective of the stretching and deformation done in the mesh. You can convert any of the ZBrush primitives into DynaMesh. Besides this, you can also convert any existing geometry into DynaMesh. However, it is recommended to convert a mesh into DynaMesh during the initial stage of sculpting. DynaMesh is used to create a base mesh in ZBrush. It enables you to freely pull or push the polygons in the mesh without creating distortions in the geometry. It is very useful for creating the base mesh before adding details to it. On converting a distorted mesh into DynaMesh, you will notice that the polygons are distributed uniformly.

DynaMesh AREA

The DynaMesh area is displayed only when an object is created in the

canvas a

znd is converted into a polymesh. The different buttons and sliders of the DynaMesh tool can be accessed by expanding the DynaMesh area in the Geometry subpalette of the Tool palette, refer to Figure 6-1. The different buttons and sliders in this area are discussed next.

DynaMesh

The DynaMesh button is used to make the distribution of polygons in a mesh uniform. To uniformly distribute polygon in a mesh, consider in a sphere in the canvas and then choose the Edit button from the top shelf. Also, conv...
