Description: Calculates the components of a mesh and sets a label for each face in the facet_component_labels array. Parameters: bUseVertexConnections- [in] If this parameter is true, then facets that share a common vertex are considered connected. If this parameter is false, then facets must share an edge to be considered connected. bUseTopologicalConnections - [in] If this parameter is true, then geometric location is used to determine if facets are connected. If this parameter is false, then facets must share the same vertex or vertices to be considered connected. facet_component_labels- [out] facet_component_labels[] will be an array with the same size as ON_Mesh.m_F.Count() and facet_component_labels[i] is the component id m_F[i] belongs to.

However, various mappings, spherical, planar, cylindrical, etc., can be applied that change the values of the texture coordinates.</p>
<p>If a texture mapping function was used to set the m_T[] values, then the id and serial number of the mapping function is saved in m_mapping_id and m_mapping_sn. The intended use of these fields is to make it easy to avoid unnecessary recalculation. If a mesh is modified, then m_mapping_id should be set to nil and m_mapping_crc should be set to 0. Implementation - surface parameters and packed texture information</p>
<p>If m_S.Count() == m_V.Count(), then the mesh is a tesselation of a parameteric surface and m_S[j] is the surface parameter at m_V[j]. Storing values in m_S[] is OPTIONAL.</p>
<p>If m_srf_scale[] has positive values, then they report the world coordinate size of a rectangle that would minimize texture distortion if it were mapped to the mesh using normalized surface evaluation parameters. This information is used to calculate high quality packed texture coordinates. </p>
