The characteristics and commands of POLYGONALmeister are explained below.

Characteristics

Explain the four features of POLYGONALmeister.
 (1) Excellent for editing polygon data derived from measurement
 (2) Manipulation of large-scale data is possible
 (3) Edit a colored mesh
 (4) Implemented with advanced geometric processing technology

Each feature is explained below.

(1) Excellent for editing polygon data derived from measurement

Compared to CAD-derived polygon data (mesh) , measurement-derived mesh has many irregularities such as self-intersections, and the smoothness of the surface is also inferior.
POLYGONALmeister has excellent editing ability even for meshes derived from measurement.

Automatic reshape

Repair the irregular part of the mesh derived from measurement, smooth the mesh, and reshape the faces to be close to equilateral triangles, just by clicking “Execute” button .

Just one click!
Reduces wavy artifacts

Semi-automatic shape correction

(2) Manipulation of large-scale data is possible

As shown in the table below, POLYGONALmeister can operate a large amount of data compared to other commercially available SWs.

POLYGONAL meister	5 sec. less than 1se.	11 sec. less than 1sec.	50 sec. few sec.	約11分 15 sec.
Software A	14 sec. 1-2 sec.	(lack of memory error)	-	-
Software B	31 sec. 1-2 sec.	70 sec. 1-2 sec.	(not displayed after 90min.)	-

(3) Edit a colored mesh

POLYGONALmeister can edit the mesh without changing the color pattern (texture, face color, vertex color) attached to the mesh as much as possible.

The textured mesh on the left of the figure below consists of mesh shape information and image information

The textured mesh on the left of the figure below consists of mesh shape information and image information.
If you perform editing processes such as simplification in the same way as a non-textured mesh, the color pattern will be broken. POLYGONALmeister can be simplified without destroying the color pattern.

(4) Implemented with advanced geometric processing technology

Based on the cutting edge technology obtained through joint research with RIKEN, we are developing POLYGONALmeister using advanced geometric processing technology.

Preserves original shape features after simplification
In the figure below, the simplification results are compared between the POLYGONALmeister and two commercially available SWs.

A curved surface with no small irregularities is estimated from the mesh, and the vertices are moved on the surface to smooth the mesh. [Polish Smoothing]

Approximate a mesh to a smooth curved surface and divide the face into small pieces so that it fits on the curved surface. The mesh will be smooth. [Subdivision]
The specified area is reshaped into a flat or cylindrical surface. [Make Flat / Cylindrical]

Commands

The following describes some commands of POLYGONALmeister.

File Import / Export

The following files can be imported / exported.
The types of color in [ ] are supported.
  STL files (ASCII or binary)
  PLY files (ASCII or binary) [face color, vertex color]
  OBJ files [texture, face color]
  VRML files [texture, face color, vertex color]
  OFF files

Edit

Cleaning

Inspect and correct the incorrect / defective parts of the mesh below.

Defeature

“Defeature” removes through holes, blind holes, dents, protrusions, self-intersections, etc. in the specified area.

Smoothing

Smooth by removing the fine irregularities on the surface of the mesh derived from the measurement.

Simplify

Reduce the number of faces that compose the mesh.

Subdivision

The bulge of a face is estimated from the bending of the surrounding faces, and the face is divided so that it rides on the bulge.
This feature allows you to smooth the mesh when the face is rough and rugged.

Remesh

Reconstructs the mesh so that each face of the mesh is closer to an equilateral triangle.
There are two types of processing methods.

Cut

Cut the mesh using a swept surface of a straight line or a polygonal line.
It is possible to remove one of the cut pieces or leave both.

When there are multiple lines of intersection, it is possible to cut using only the selected lines.

Boolean Operation

Create union / difference / intersection of two shells.

Arrange Shells

Arrange shells according to various conditions.

Match two shells with similar shapes as closely as possible.

Move to match the 3 pairs of vertices.

Move so that the axis of cylinder A coincides with the axis of cylinder B.

Fill Caves

This function detects through holes and blind holes of a mesh and fills them.

Reshape Hole

Compensate for the irregularities in the round hole (through holes, blind holes, and holes in shells) to round.

Make Flat / Cylindrical

The specified area is reshaped into a flat or cylindrical surface.

Remove Protrusion

Detects and removes protrusions on the mesh.

Projection Solid

Sweep the open shell to a plane to create a solid shell.

Loop Cut

Cut with a free curve (polyline) in an inconspicuous place such as a color boundary

Reshape CT Mesh

Repair the irregular part of the mesh derived from CT measurement, smooth the mesh, and reshape the faces to be close to equilateral triangles.

Reshape Optical Mesh

Repair the irregular part of the mesh derived from CT measurement, fills small holes, smooth the mesh, and reshape the faces to be close to equilateral triangles.

Extension

Extend the mesh smoothly at the shell boundary.

Evaluation

Distance Contour

The difference between the two shapes is represented by a color map.

Example: Difference between before and after performing “Reshape CT mesh”

Thickness Inspection

The color map of the mesh thickness is displayed.

Display Section Lines

Display intersections between the mesh and planes.

Find Path

Displays the shortest path (edge string) connecting two vertices.

Other evaluation functions

- Property
  The following features related to the shape of the mesh are displayed.
  - Surface area, Volume
  - Center of gravity
  - Size(Length of the range where the mesh exists in each coordinate axis direction.)
  - Number of shells
  - Number of shell boundaries
  - Average / Maximum / Minimum edge length

Color

Texture Alignment

Changes the area of the texture image referenced by the face.

Transfer Color

Pastes the mesh color of the external file into the (working) mesh as a texture.

Convert to Vertex Color

Change the "texture" or "face color" on the mesh to "vertex color".
This function is effective when the SW in the post-process cannot handle textures.

Segmentation

Divide the mesh into multiple color-coded areas based on shape feature.

Edit Segment Boundary

Merge segments that were divided by "Segmentation" command, and smooth a segment boundary.
