EggVertexUV¶

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.

Inheritance diagram

__init__(copy: EggVertexUV)¶

__init__(name: str, uvw: panda3d.core.LTexCoord3d)

__init__(name: str, uv: panda3d.core.LTexCoordd)

property _duvs → EggMorphTexCoordList¶: getter for EggMorphTexCoordList EggVertexUV::_duvs;

assign(copy: EggVertexUV) → EggVertexUV ¶

clearBinormal()¶

clearTangent()¶

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.

write(out: panda3d.core.ostream, indent_level: int)¶
