MeshFactoryCreateExtrudedMesh(Vector2, Int32, Vector2, Boolean, Boolean, Vector3, Vector3, Vector3, MeshFactoryExtrudeTextureCoordinatesGenerationType, Boolean, Boolean, Boolean, String) Method

Generate a mesh extruded from multiple 2D shapes. The base surface is defined by sequence of positions and triangle indices, and is extruded in the direction of the extrudeVector. The texture coordinates are generated according to the textureCoordinatesGenerationType parameter.

Parameters

triangulatedPositions  Vector2
Array of 2D positions that was generated by the Triangulator from allPolygons.
triangleIndices  Int32
Array of indices that was generated by the Triangulator from allPolygons.
allPolygons  Vector2
The original 2D positions that define the outer polygons and holes.
isSmooth  Boolean
If true, the mesh appears smooth, otherwise the edges are sharp.
flipNormals  Boolean
Flip the normals. Use when triangles are defined in counter-clockwise direction.
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.
isYAxisUp  Boolean  (Optional)
When false (by default), then the Y axis in the 2D coordinate system is pointing down - (0,0) is the top-left position; true if Y axis is pointing up.
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
ArgumentExceptionThrown when fewer than 3 positions are given.
ExceptionThrown when extrudeVector and shapeYVector are parallel or close to parallel.
