static const EggVertexUV * | second |
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.
Definition at line 32 of file eggVertexUV.h.
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 188 of file eggVertexUV.cxx.

inlinestatic |
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.

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).

Returns the texture coordinate pair, if get_num_dimensions() is 2.

|
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).

Returns true if the texture coordinate has a third, w component, false if it is just a normal 2-d texture coordinate.

Sets the texture coordinate pair.
This makes the texture coordinate a 2-d texture coordinate, which is the usual case.

Sets the texture coordinate triple.

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.
