MeshFactoryCreateExtrudedMesh(Vector2, Boolean, Vector3, Vector3, Vector3, MeshFactoryExtrudeTextureCoordinatesGenerationType, Boolean, Boolean, String) Method

Generate a mesh extruded from a 2D shape. The base surface is defined by a polygon given as a sequence of positions, and is extruded in the direction of the extrudeVector. The texture coordinates are generated according to the textureCoordinatesGenerationType parameter.

Namespace: Ab4d.SharpEngine.Meshes
Assembly: Ab4d.SharpEngine (in Ab4d.SharpEngine.dll) Version: 2.0.8956+4c7684e186ca1be74e7a284fbe739d9a1b843d3c
Syntax
C#
public static StandardMesh CreateExtrudedMesh(
	Vector2[] positions,
	bool isSmooth,
	Vector3 modelOffset,
	Vector3 extrudeVector,
	Vector3 shapeYVector,
	MeshFactoryExtrudeTextureCoordinatesGenerationType textureCoordinatesGenerationType = MeshFactoryExtrudeTextureCoordinatesGenerationType.Cylindrical,
	bool closeBottom = true,
	bool closeTop = true,
	string? name = null
)

Parameters

positions  Vector2
Array of 2D positions that define the base shape polygon.
isSmooth  Boolean
If true, the mesh appears smooth, otherwise the edges are sharp.
modelOffset  Vector3
A 3D vector defining the offset of the model. This offset is applied to each position.
extrudeVector  Vector3
A 3D vector that defines the extrusion, i.e., the direction and the distance between the bottom and top surface.
shapeYVector  Vector3
A 3D vector that defines the 3D direction along the 2D shape surface (i.e., the Y axis of the base 2D shape).
textureCoordinatesGenerationType  MeshFactoryExtrudeTextureCoordinatesGenerationType  (Optional)
Type of texture coordinate generation. By default, cylindrical projection is used.
closeBottom  Boolean  (Optional)
Close the bottom surface of the mesh (true by default).
closeTop  Boolean  (Optional)
Close the top surface of the mesh (true by default).
name  String  (Optional)
Mesh name (for debug purposes).

Return Value

StandardMesh
StandardMesh with filled vertices array and index array.
Exceptions
ExceptionCondition
ExceptionThrown when the base 2D shape cannot be triangulated into the 3D surface.
Remarks

This method uses Triangulator to create 3D surface from the given 2D polygon. Therefore, it may throw FormatException when shape positions are not correctly defined, for example, if lines intersect each other.
