 Sets the user data associated with this object. This may be any EggUserData-derived object. The egg library will do nothing with this pointer, except to hold its reference count and return the pointer on request. More...

 Derived classes should override this function to return get_class_type(). More...

 Returns the internal index number associated with this object's TypeHandle, a unique number for each different type. This is equivalent to get_type().get_index(). More...

int getRefCount ()
 Returns the current reference count. More...
 
 ref ()
 Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. More...
 
bool testRefCountIntegrity ()
 Does some easy checks to make sure that the reference count isn't completely bogus. Returns true if ok, false otherwise. More...
 
bool testRefCountNonzero ()
 Does some easy checks to make sure that the reference count isn't zero, or completely bogus. Returns true if ok, false otherwise. More...
 
bool unref ()
 Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete(). More...

 Returns true if the Namable has a nonempty name set, false if the name is empty. More...
 
Namable operator= (const Namable other)

 Outputs the Namable. This function simply writes the name to the output stream; most Namable derivatives will probably redefine this. More...

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.

int compareTo ( const EggVertexUV  other)

An ordering operator to compare two vertices for sorting order. This imposes an arbitrary ordering useful to identify unique vertices.

◆ filterName()

static str filterName ( str  name)
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.

◆ getBinormal()

const LNormald getBinormal ( )

◆ getClassType()

static TypeHandle getClassType ( )
static

◆ getNumDimensions()

int getNumDimensions ( )

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).

◆ getTangent()

const LNormald getTangent ( )

◆ getUv()

LTexCoordd getUv ( )

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

◆ getUvw()

const LTexCoord3d getUvw ( )

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).

◆ hasBinormal()

bool hasBinormal ( )

◆ hasTangent()

bool hasTangent ( )

◆ hasW()

bool hasW ( )

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

◆ makeAverage()

static EggVertexUV makeAverage ( const EggVertexUV  first,
const EggVertexUV  second 
)
static

Creates a new EggVertexUV that contains the averaged values of the two given objects. It is an error if they don't have the same name.

◆ setName()

setName ( str  name)

◆ setTangent()

setTangent ( const LNormald  tangent)

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

◆ setUvw()

setUvw ( const LTexCoord3d  texCoord)

Sets the texture coordinate triple. This makes the texture coordinate a 3-d texture coordinate.

◆ transform()

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.
