Tool Additions
Reduce
The reduce node returns a new Mesh with a reduced number of triangles. Users provide a goal triangle count for the reduction in which the new mesh targets. If the operation is unable to meet to the goal it will provide the greatest reduction it can achieve.
Smooth
The smooth node returns a new smooth mesh using a cotangent smoothing algorithm. Cotangent smoothing refrains from spreading the vertices from their original position. The scaling input sets the “spatial scale” of the smoothing meaning smaller values yield more local smoothing, and typically result in a less “smooth” looking result (0.1 – 64.0).
Plane Cut
The plane cut node creates a precise geometric planar cut which removes portions of the mesh that lie on the side of the plane in the opposite direction of the plane normal. The make solid boolean input provides the option to create a minimal fill using the fewest number of triangles.
Generate Support
The generate support node automatically calculates overhangs and returns a new mesh with support structure. The output is a single mesh object, however this consists of two solid meshes to assist in cleaner support removal. By default all input nodes are provided with standard recommended settings. The input parameters operate in the following way…
Base Height – Height of the base where the support posts meet the ground.
Base Diameter – Diameter of the base where the support posts meet the ground.
Post Diameter – Diameter of the support posts.
Tip Height – Height of the tip where the support posts touch the mesh.
Tip Diameter – Diameter of the tip where the support posts touch the mesh.
Make Hollow
The make hollow node can be used to hollow out a mesh object in preparation for 3D printing and is particularly useful in powder based printing methods. Hollowing a mesh model significantly reduces the amount of print material required and reduces overall printing time and cost. Escape holes are generated in the hollowed mesh to allow excess material to be removed during the printing process. The input parameters operate in the following way…
Hole Count – Number of escape holes to be generated.
Hole Radius – Radius of escape holes.
Wall Thickness – Interior offset distance from original mesh.
Solid Resolution – Resolution for making the solid that represents the interior surface of the hollowed mesh (8 – 4096).
Mesh Resolution – Resolution for mesh generation on the interior surface of the hollowed mesh (8 – 4096)
Remesh
The remesh node returns a new mesh distributing triangles more evenly over the whole of the selection regardless of any change in triangle normals.
Volume
The volume node simply returns the volume of a solid non-intersecting mesh. This calculation can also be helpful in determining if a mesh is indeed solid and non-intersecting.
Future Plans
Additional tools are already in the works! Without making too many promises I can confirm experimentation with some analysis, coloring, and new mesh creation/modification tools. Be on the lookout for a second update later this summer.
