This is the Mesh to Volume node, and is very handy to be creative with defining shapes via mathematics, as we’ll learn in the coming chapters.

Figure 2.17: The Mesh to Volume node This node allows you to convert your mesh to a volume. One use case example of this node is that, if we take a mesh with messy geometry, and we make a volume out of it, and we take that volume and convert it back into a mesh using the Volume to Mesh node, we can get a clean topology for our objects, much like the Remesh function.The Mesh to Volume node has six inputs. For starters, it has the standard Mesh input that most mesh nodes have. Below the Mesh input, you will see the Density input. This value will define the density of the volume. A higher value means more densely packed volumes.Voxel Amount defines the resolution of your volume. In other words, it defines the number of voxels your volume is allowed to contain. A Voxel is a volume element; it literally stands for volumetric pixel. Here, you can see a visual demonstration of how the voxel amount progresses:

Turning this value up will create a smoother gradient to the inside of your volume. The lower this value is set, the thicker the sides of your volume are. Most of the time you won’t be using this setting.
