Member Function Documentation

void CLwoPolygons::add_ptags (  const LwoPolygonTags *  lwo_ptags, const LwoTags *  tags )

Associates the indicated PolygonTags and Tags with the polygons in this chunk. This may define features such as per-polygon surfaces, parts, and smoothing groups. Definition at line 51 of file cLwoPolygons.cxx. References nout.

void CLwoPolygons::add_vmad (  const LwoDiscontinuousVertexMap *  lwo_vmad  )

Associates the indicated DiscontinousVertexMap with the polygons. This can be used in conjunction with (or in place of) the VertexMap associated with the points set, to define per-polygon UV's etc. Definition at line 86 of file cLwoPolygons.cxx.

void CLwoPolygons::connect_egg (   )

Connects all the egg structures together. Definition at line 246 of file cLwoPolygons.cxx. References nout.

CLwoSurface * CLwoPolygons::get_surface (  int  polygon_index  )  const

Returns the surface associated with the given polygon, or NULL if no surface is associated. Definition at line 116 of file cLwoPolygons.cxx. References _converter, _tags, nout, and NULL.

bool CLwoPolygons::get_uv (  const string &  uv_name, int  pi, int  vi, LPoint2f &  uv )  const

Returns true if there is a UV of the indicated name associated with the given vertex of the indicated polygon, false otherwise. If true, fills in uv with the value. This performs a lookup in the optional "discontinuous" vertex mapping, which provides the ability to map different UV's per each polygon for the same vertex. If the UV is not defined here, it may also be defined in the standard vertex map, which is associated with the points themselves. Definition at line 176 of file cLwoPolygons.cxx. References _egg_group, _polygons, and nout. Referenced by make_faces().

void CLwoPolygons::make_egg (   )

Creates the egg structures associated with this Lightwave object. Definition at line 210 of file cLwoPolygons.cxx. References _points.

void CLwoPolygons::make_faces (   )  [private]

Generates "face" polygons, i.e. actual polygons. Definition at line 262 of file cLwoPolygons.cxx. References _points, CLwoPoints::get_uv(), get_uv(), CLwoSurface::get_uv_name(), LCAST, and NULL.
