Inheritance diagram
-
__init__() → None¶
-
__init__(point: LPoint3i) → None Constructs an LVecBase4 from an LPoint3. The w coordinate is set to 1.0.
-
__init__(copy: LVecBase3i, w: int) → None
-
__init__(param0: LVecBase4i) → None
-
__init__(vector: LVector3i) → None Constructs an LVecBase4 from an LVector3. The w coordinate is set to 0.0.
-
__init__(copy: UnalignedLVecBase4i) → None
-
__init__(fill_value: int) → None
-
__init__(x: int, y: int, z: int, w: int) → None
-
operatorNew(size: size_t) → None¶
-
assign(copy: LVecBase4i) → LVecBase4i¶ - Return type
-
assign(fill_value: int) → LVecBase4i - Return type
-
static
zero() → LVecBase4i¶ Returns a zero-length vector.
- Return type
-
static
unitX() → LVecBase4i¶ Returns a unit X vector.
- Return type
-
static
unitY() → LVecBase4i¶ Returns a unit Y vector.
- Return type
-
static
unitZ() → LVecBase4i¶ Returns a unit Z vector.
- Return type
-
static
unitW() → LVecBase4i¶ Returns a unit W vector.
- Return type
-
static
size() → int¶
-
isNan() → bool¶ Returns true if any component of the vector is not-a-number, false otherwise.
-
getCell(i: int) → int¶
-
setCell(i: int, value: int) → None¶
-
getX() → int¶
-
getY() → int¶
-
getZ() → int¶
-
getW() → int¶
-
getXyz() → LVecBase3i¶ Returns the x, y and z component of this vector
- Return type
-
getXy() → LVecBase2i¶ Returns the x and y component of this vector
- Return type
-
setX(value: int) → None¶
-
setY(value: int) → None¶
-
setZ(value: int) → None¶
-
setW(value: int) → None¶
-
addToCell(i: int, value: int) → None¶ These next functions add to an existing value. i.e. foo.set_x(foo.get_x() + value) These are useful to reduce overhead in scripting languages:
-
addX(value: int) → None¶
-
addY(value: int) → None¶
-
addZ(value: int) → None¶
-
addW(value: int) → None¶
-
getData() → None¶ Returns the address of the first of the four data elements in the vector. The remaining elements occupy the next positions consecutively in memory.
-
static
getNumComponents() → int¶
-
fill(fill_value: int) → None¶ Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.
-
set(x: int, y: int, z: int, w: int) → None¶
-
dot(other: LVecBase4i) → int¶
-
lengthSquared() → int¶ Returns the square of the vector’s length, cheap and easy.
-
compareTo(other: LVecBase4i) → int¶ This flavor of compare_to uses a default threshold value based on the numeric type.
-
getHash() → size_t¶ Returns a suitable hash for phash_map.
- Return type
size_t
-
addHash(hash: size_t) → size_t¶ Adds the vector into the running hash.
- Return type
size_t
-
generateHash(hashgen: ChecksumHashGenerator) → None¶ Adds the vector to the indicated hash generator.
-
componentwiseMult(other: LVecBase4i) → None¶
-
fmax(other: LVecBase4i) → LVecBase4i¶ - Return type
-
fmin(other: LVecBase4i) → LVecBase4i¶ - Return type
-
almostEqual(other: LVecBase4i) → bool¶ Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.
-
almostEqual(other: LVecBase4i, threshold: int) → bool Returns true if two vectors are memberwise equal within a specified tolerance.
-
output(out: ostream) → None¶
-
writeDatagramFixed(destination: Datagram) → None¶ Writes the vector to the Datagram using add_float32() or add_float64(), depending on the type of floats in the vector, regardless of the setting of
Datagram.setStdfloatDouble(). This is appropriate when you want to write a fixed-width value to the datagram, especially when you are not writing a bam file.
-
readDatagramFixed(source: DatagramIterator) → None¶ Reads the vector from the Datagram using get_float32() or get_float64(). See
writeDatagramFixed().
-
writeDatagram(destination: Datagram) → None¶ Writes the vector to the Datagram using add_stdfloat(). This is appropriate when you want to write the vector using the standard width setting, especially when you are writing a bam file.
-
readDatagram(source: DatagramIterator) → None¶ Reads the vector from the Datagram using get_stdfloat().
