add_hash()¶

Adds the vector into the running hash.

add_to_cell()¶: 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:

add_x()¶

add_y()¶

add_z()¶

almost_equal()¶

Returns true if two vectors are memberwise equal within a specified tolerance.

Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.

assign()¶

compare_to()¶

This flavor of compare_to uses a default threshold value based on the numeric type.

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).

componentwise_mult()¶

cross()¶

cross_into()¶

dot()¶

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

fmax()¶

fmin()¶

generate_hash()¶

Adds the vector to the indicated hash generator.

get_cell()¶

static get_class_type()¶

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

get_hash()¶

Returns a suitable hash for phash_map.

static get_num_components()¶

get_standardized_hpr()¶

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.is_same_direction() for that. See Also: get_standardized_rotation, LQuaternion::is_same_direction

get_x()¶

get_xy()¶: Returns a 2-component vector that shares just the first two components of this vector.

get_xz()¶: Returns a 2-component vector that shares just the first and last components of this vector.

get_y()¶

get_yz()¶: Returns a 2-component vector that shares just the last two components of this vector.

get_z()¶

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

length()¶: Returns the length of the vector, by the Pythagorean theorem.

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

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

normalized()¶: 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.

static operator_delete()¶

static operator_delete()¶

static operator_new()¶

static operator_new()¶

output()¶

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

read_datagram()¶: Reads the vector from the Datagram using get_stdfloat().

read_datagram_fixed()¶: Reads the vector from the Datagram using get_float32() or get_float64(). See write_datagram_fixed().

set()¶

set_cell()¶

set_x()¶

set_y()¶

set_z()¶

static size()¶

static unit_x()¶: Returns a unit X vector.

static unit_y()¶: Returns a unit Y vector.

static unit_z()¶: Returns a unit Z vector.

static validate_ptr()¶

write_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.

write_datagram_fixed()¶: 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.set_stdfloat_double(). 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 → float¶

property xy → LVecBase2f¶: Returns a 2-component vector that shares just the first two components of this vector.

property y → float¶

property yz → LVecBase2f¶: Returns a 2-component vector that shares just the last two components of this vector.
