The set of UV's that may or may not be assigned to a vertex.
To support multitexturing, there may be multiple sets of UV's on a particular vertex, each with its own name.

int EggVertexUV::compare_to | ( | const EggVertexUV & | other | ) | const |
An ordering operator to compare two vertices for sorting order.
This imposes an arbitrary ordering useful to identify unique vertices.
Definition at line 163 of file eggVertexUV.cxx.
References LVecBase3d::compare_to().
string EggVertexUV::filter_name | ( | const string & | name | ) | [inline, static] |
Returns the actual name that should be set for a given name string.
Usually this is the same string that is input, but for historical reasons the texture coordinate name "default" is mapped to the empty string.

int EggVertexUV::get_num_dimensions | ( | ) | const [inline] |
Returns the number of components of the texture coordinate set.
This is either 2 (the normal case) or 3 (for a 3-d texture coordinate).
Definition at line 51 of file eggVertexUV.I.
References has_w().
LTexCoordd EggVertexUV::get_uv | ( | ) | const [inline] |
Returns the texture coordinate pair, if get_num_dimensions() is 2.
Definition at line 74 of file eggVertexUV.I.
References has_w(), and LPoint2d::zero().
const LTexCoord3d & EggVertexUV::get_uvw | ( | ) | const [inline] |
Returns the texture coordinate triple, if get_num_dimensions() is 3.
This is also legal to call if get_num_dimensions() is 2 (but the last dimension will be zero).

bool EggVertexUV::has_w | ( | ) | const [inline] |
Returns true if the texture coordinate has a third, w component, false if it is just a normal 2-d texture coordinate.

static void EggVertexUV::init_type | ( | ) | [inline, static] |
This function is declared non-inline to work around a compiler bug in g++ 2.96.
Making it inline seems to cause problems in the optimizer.
Reimplemented from EggNamedObject.
Definition at line 83 of file eggVertexUV.h.
References EggNamedObject::init_type().
void EggVertexUV::set_uv | ( | const LTexCoordd & | uv | ) | [inline] |
Sets the texture coordinate pair.
This makes the texture coordinate a 2-d texture coordinate, which is the usual case.
Definition at line 100 of file eggVertexUV.I.
void EggVertexUV::set_uvw | ( | const LTexCoord3d & | uvw | ) | [inline] |
Sets the texture coordinate triple.
This makes the texture coordinate a 3-d texture coordinate.
Definition at line 112 of file eggVertexUV.I.
void EggVertexUV::transform | ( | const LMatrix4d & | mat | ) |
Applies the indicated transformation matrix to the UV's tangent and/or binormal.
This does nothing if there is no tangent or binormal.
