from panda3d.egg import EggVertexUV
class EggVertexUV


Bases: EggNamedObject

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.

property _duvs EggMorphTexCoordList

getter for EggMorphTexCoordList EggVertexUV::_duvs;

assign(copy: EggVertexUV) EggVertexUV
compareTo(other: EggVertexUV) int

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

static filterName(name: str) str

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() panda3d.core.LNormald
static getClassType() panda3d.core.TypeHandle
getNumDimensions() int

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() panda3d.core.LNormald
getTangent4() panda3d.core.LVecBase4d
getUv() panda3d.core.LTexCoordd

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

getUvw() panda3d.core.LTexCoord3d

Returns the texture coordinate triple, if getNumDimensions() is 3. This is also legal to call if getNumDimensions() is 2 (but the last dimension will be zero).

hasBinormal() bool
hasTangent() bool
hasTangent4() bool
hasW() bool

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

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

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.

setBinormal(binormal: panda3d.core.LNormald)
setName(name: str)
setTangent(tangent: panda3d.core.LNormald)
setTangent4(tangent: panda3d.core.LVecBase4d)

Sets the tangent vector, along with a fourth parameter that is multiplied with the result of cross(normal, tangent) when computing the binormal.

setUv(texCoord: panda3d.core.LTexCoordd)

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

setUvw(texCoord: panda3d.core.LTexCoord3d)

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

transform(mat: panda3d.core.LMatrix4d)

Applies the indicated transformation matrix to the UV’s tangent and/or binormal. This does nothing if there is no tangent or binormal.
