MeshFactoryCreateExtrudedMesh(Vector2, Int32, Boolean, Boolean, Vector3, Vector3, Vector3, MeshFactoryExtrudeTextureCoordinatesGenerationType, Boolean, Boolean, Boolean, String) Method |
Generate a mesh extruded from a 2D shape. 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
- positions Vector2
- Array of 2D positions that define the base shape polygon.
- triangleIndices Int32
- Optional array of indices that define triangles that define the base surface from positions. If not provided, it is assumed that triangles are defined by consecutive position triplets.
- 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
StandardMeshStandardMesh with filled vertices array and index array.
Exceptions Exception | Condition |
