Static Public Member Functions | |
| static string | filterName (string name) |
| Returns the actual name that should be set for a given name string. | |
| static TypeHandle | getClassType () |
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.

| clearBinormal | ( | ) |
| clearTangent | ( | ) |
| int compareTo | ( | EggVertexUV const | other | ) |
An ordering operator to compare two vertices for sorting order.
This imposes an arbitrary ordering useful to identify unique vertices.
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.
| Vec3D const getBinormal | ( | ) |
| static TypeHandle getClassType | ( | ) | [static] |
Reimplemented from EggNamedObject.
| 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).
| Vec3D const getTangent | ( | ) |
| Point2D getUv | ( | ) |
Returns the texture coordinate pair, if get_num_dimensions() is 2.
| Point3D const 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).
| bool hasBinormal | ( | ) |
| bool hasTangent | ( | ) |
| bool hasW | ( | ) |
Returns true if the texture coordinate has a third, w component, false if it is just a normal 2-d texture coordinate.
| EggVertexUV operator= | ( | EggVertexUV const | copy | ) |
| setBinormal | ( | Vec3D const | binormal | ) |
| setName | ( | string | name | ) |
| setTangent | ( | Vec3D const | tangent | ) |
| setUv | ( | Point2D const | texCoord | ) |
Sets the texture coordinate pair.
This makes the texture coordinate a 2-d texture coordinate, which is the usual case.
| setUvw | ( | Point3D const | texCoord | ) |
Sets the texture coordinate triple.
This makes the texture coordinate a 3-d texture coordinate.
| transform | ( | Mat4D const | mat | ) |
Applies the indicated transformation matrix to the UV's tangent and/or binormal.
This does nothing if there is no tangent or binormal.
