MESH_ISSOLID

The MESH_ISSOLID function computes various mesh properties and enables IDL to determine if a mesh encloses space (is a solid). If the mesh can be considered a solid, routines can compute the volume of the mesh.

Syntax

Result = MESH_ISSOLID (Conn)

Return Value

Returns 1 if the input mesh fully encloses space (assuming no polygonal interpenetration) or 0 otherwise. A mesh is defined to fully enclose space if each edge in the input mesh appears an even number of times in the mesh.

Note: The input polygonal mesh is assumed to contain only planar, convex polygons.

Arguments

Conn

This is an integer or longword array that represents a series of polygon descriptions. Each polygon description takes the form [n, i₀, i₁, ..., i_n_-1], where n is the number of vertices that define the polygon, and i₀...i_n_-1 are indices into the vertex array.

Keywords

None.
