Mesh Class

The Mesh class represents a mesh for drawing three-dimensional data.
Inheritance Hierarchy

Namespace:  Tekla.Structures.Model.UI
Assembly:  Tekla.Structures.Model (in Tekla.Structures.Model.dll) Version: 2023.0.1
public sealed class Mesh

The Mesh type exposes the following members.

Public methodMesh
Creates a new empty mesh instance.
Public methodMesh(ArrayList, ArrayList, ArrayList)
Creates a new mesh instance with the given points, triangles and lines. Does not check the indices in the given triangles and lines array lists for correctness.
Public propertyLines
An array list of indices (as integers) pointing to the points array list. Two consecutive indices always represent a single line.
Public propertyPoints
An array list of point objects representing the mesh points.
Public propertyTriangles
An array list of indices (as integers) pointing to the points array list. Three consecutive indices always represent a single triangle.
Public methodAddLine
Adds a new line in the mesh.
Public methodAddPoint
Adds a new point in the mesh.
Public methodAddTriangle
Adds a new triangle in the mesh.
