addToCell
(i: int, value: float) → 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:
-
almostEqual
(other: LVecBase3d) → bool¶ Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.
-
almostEqual
(other: LVecBase3d, threshold: float) → bool Returns true if two vectors are memberwise equal within a specified tolerance.
-
assign
(copy: LVecBase3d) → LVecBase3d¶
-
assign
(fill_value: float) → LVecBase3d
-
compareTo
(other: LVecBase3d) → int¶ This flavor of
compareTo()
uses a default threshold value based on the numeric type.
-
compareTo
(other: LVecBase3d, 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: LVecBase3d) → None¶
-
cross
(other: LVecBase3d) → LVecBase3d¶
-
crossInto
(other: LVecBase3d) → None¶
-
dot
(other: LVecBase3d) → float¶
-
fill
(fill_value: float) → None¶ Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.
-
fmax
(other: LVecBase3d) → LVecBase3d¶
-
fmin
(other: LVecBase3d) → LVecBase3d¶
-
generateHash
(hashgen: ChecksumHashGenerator) → None¶ Adds the vector to the indicated hash generator.
-
generateHash
(hashgen: ChecksumHashGenerator, threshold: float) → None Adds the vector to the indicated hash generator.
-
static
getClassType
() → TypeHandle¶
-
getData
() → None¶ Returns the address of the first of the three data elements in the vector. The remaining elements occupy the next positions consecutively in memory.
-
getStandardizedHpr
() → LVecBase3d¶ Try to un-spin the hpr to a standard form. Like all standards, someone decides between many arbitrary possible standards. This function assumes that 0 and 360 are the same, as is 720 and -360. Also 180 and -180 are the same. Another example is -90 and 270. Each element will be in the range -180.0 to 179.99999. The original usage of this function is for human readable output.
It doesn’t work so well for asserting that foo_hpr is roughly equal to bar_hpr. Try using
LQuaternionf.isSameDirection()
for that. See Also: get_standardized_rotation, LQuaternion::is_same_direction
-
getXy
() → LVecBase2d¶ Returns a 2-component vector that shares just the first two components of this vector.
-
getXz
() → LVecBase2d¶ Returns a 2-component vector that shares just the first and last components of this vector.
-
getYz
() → LVecBase2d¶ Returns a 2-component vector that shares just the last two components of this vector.
-
normalize
() → bool¶ Normalizes the vector in place. Returns true if the vector was normalized, false if it was a zero-length vector.
-
normalized
() → LVecBase3d¶ 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.
-
project
(onto: LVecBase3d) → LVecBase3d¶ 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) → None¶ Reads the vector from the Datagram using get_stdfloat().
-
readDatagramFixed
(source: DatagramIterator) → None¶ Reads the vector from the Datagram using get_float32() or get_float64(). See
writeDatagramFixed()
.
-
static
unitX
() → LVecBase3d¶ Returns a unit X vector.
-
static
unitY
() → LVecBase3d¶ Returns a unit Y vector.
-
static
unitZ
() → LVecBase3d¶ Returns a unit Z vector.
-
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.
-
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.
-
property
xy
→ LVecBase2d¶ Returns a 2-component vector that shares just the first two components of this vector.
-
property
xz
→ LVecBase2d¶ Returns a 2-component vector that shares just the first and last components of this vector.
-
property
yz
→ LVecBase2d¶ Returns a 2-component vector that shares just the last two components of this vector.
-
static
zero
() → LVecBase3d¶ Returns a zero-length vector.
