__init__()¶

__init__(point: LPoint3i): Constructs an LVecBase4 from an LPoint3. The w coordinate is set to 1.0.

__init__(copy: LVecBase3i, w: int)

__init__(param0: LVecBase4i)

__sub__(other: LVecBase4i) → LVecBase4i ¶

__sub__(other: LVecBase4i) → LVecBase4i ¶

addHash(hash: int) → int ¶: Adds the vector into the running hash.

addToCell(i: int, value: int)¶: 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:

addW(value: int)¶

addX(value: int)¶

addY(value: int)¶

addZ(value: int)¶

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.

assign(copy: LVecBase4i) → LVecBase4i ¶

assign(fill_value: int) → LVecBase4i

compareTo(other: LVecBase4i) → int ¶: This flavor of compareTo() uses a default threshold value based on the numeric type.

componentwiseMult(other: LVecBase4i)¶

dot(other: LVecBase4i) → int ¶

fill(fill_value: int)¶: Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.

fmax(other: LVecBase4i) → LVecBase4i ¶

fmin(other: LVecBase4i) → LVecBase4i ¶

generateHash(hashgen: ChecksumHashGenerator)¶: Adds the vector to the indicated hash generator.

getCell(i: int) → int ¶

static getClassType() → TypeHandle ¶

getData()¶: Returns the address of the first of the four data elements in the vector. The remaining elements occupy the next positions consecutively in memory.

getHash() → int ¶: Returns a suitable hash for phash_map.

static getNumComponents() → int ¶

getW() → int ¶

getX() → int ¶

getXy() → LVecBase2i ¶: Returns the x and y component of this vector

getXyz() → LVecBase3i ¶: Returns the x, y and z component of this vector

getY() → int ¶

getZ() → int ¶

isNan() → bool ¶: Returns true if any component of the vector is not-a-number, false otherwise.

lengthSquared() → int ¶: Returns the square of the vector’s length, cheap and easy.

operatorNew(size: int)¶

output(out: ostream)¶

readDatagram(source: DatagramIterator)¶: Reads the vector from the Datagram using get_stdfloat().

readDatagramFixed(source: DatagramIterator)¶: Reads the vector from the Datagram using get_float32() or get_float64(). See writeDatagramFixed().

set(x: int, y: int, z: int, w: int)¶

setCell(i: int, value: int)¶

setW(value: int)¶

setX(value: int)¶

setY(value: int)¶

setZ(value: int)¶

static size() → int ¶

static unitW() → LVecBase4i ¶: Returns a unit W vector.

static unitX() → LVecBase4i ¶: Returns a unit X vector.

static unitY() → LVecBase4i ¶: Returns a unit Y vector.

static unitZ() → LVecBase4i ¶: Returns a unit Z vector.

writeDatagram(destination: Datagram)¶: 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.

writeDatagramFixed(destination: Datagram)¶: 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.

property x → int ¶

property xy → LVecBase2i ¶: Returns the x and y component of this vector

property xyz → LVecBase3i ¶: Returns the x, y and z component of this vector

property y → int ¶

property z → int ¶

static zero() → LVecBase4i ¶: Returns a zero-length vector.
