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

addHash(hash: int, threshold: float) → int: Adds the vector into the running hash.

almostEqual(other: LVecBase4f) → bool: Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.

compareTo(other: LVecBase4f) → int: This flavor of compareTo() uses a default threshold value based on the numeric type.

compareTo(other: LVecBase4f, threshold: float) → int: Sorts vectors lexicographically, componentwise. Returns a number less than 0 if this vector sorts before the other one, greater than zero if it sorts after, 0 if they are equivalent (within the indicated tolerance).

componentwiseMult(other: LVecBase4f)

dot(other: LVecBase4f) → float

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

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

length() → float: Returns the length of the vector, by the Pythagorean theorem.

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

normalize() → bool: Normalizes the vector in place. Returns true if the vector was normalized, false if it was a zero-length vector.

normalized() → LVecBase4f: Normalizes the vector and returns the normalized vector as a copy. If the vector was a zero-length vector, a zero length vector will be returned.

operatorNew(size: int)

output(out: ostream)

project(onto: LVecBase4f) → LVecBase4f: Returns a new vector representing the projection of this vector onto another one. The resulting vector will be a scalar multiple of onto.

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().

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.
