This tool creates a vector triangular irregular network (TIN) for a set of vector points (`input`) using a 2D Delaunay triangulation algorithm. TIN vertex heights can be assigned based on either a field in the vector's attribute table (`field`), or alternatively, if the vector is of a z-dimension VectorGeometryTypeDimension, the point z-values may be used for vertex heights (`use_z`). For LiDAR points, use the lidar_construct_vector_tin tool instead.

Triangulation often creates very long, narrow triangles near the edges of the data coverage, particularly in convex regions along the data boundary. To avoid these spurious triangles, the user may optionally specify the maximum allowable edge length of a triangular facet (`max_triangle_edge_length`).
