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 29 of file eggVertexUV.h.

Member Function Documentation

◆ compare_to()

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 166 of file eggVertexUV.cxx.

◆ filter_name()

std::string EggVertexUV::filter_name ( const std::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 20 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().

◆ get_num_dimensions()

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 40 of file eggVertexUV.I.

References has_w().

◆ get_uv()

LTexCoordd EggVertexUV::get_uv ( ) const

inline

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

Definition at line 57 of file eggVertexUV.I.

◆ get_uvw()

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 68 of file eggVertexUV.I.

◆ has_w()

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 49 of file eggVertexUV.I.

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

◆ set_uv()

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 77 of file eggVertexUV.I.

◆ set_uvw()

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 87 of file eggVertexUV.I.

◆ transform()

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.
