Detailed Description

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.

Member Function Documentation

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.

References LVecBase3d::compare_to().

string EggVertexUV::filter_name ( const string &  name)
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.

Definition at line 26 of file eggVertexUV.I.

Referenced by EggVertex::clear_uv(), EggVertex::get_uv(), EggVertex::get_uv_obj(), EggVertex::get_uvw(), EggVertex::has_uv(), EggVertex::has_uvw(), EggVertex::modify_uv_obj(), EggVertex::set_uv(), and EggVertex::set_uvw().

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).

Definition at line 88 of file eggVertexUV.I.

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.

Definition at line 63 of file eggVertexUV.I.

Referenced by get_num_dimensions(), get_uv(), EggVertexPool::get_uv_names(), EggVertex::has_uv(), and EggVertex::has_uvw().

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.

Definition at line 129 of file eggVertexUV.cxx.
