MESH_ISSOLID

Syntax | Return Value | Arguments | Keywords | Version History | See Also

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.
