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_w()¶

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.

componentwise_mult()¶

dot()¶

static extract_data()¶

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 four 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_w()¶

get_x()¶

get_xy()¶: Returns the x and y component of this vector

get_xyz()¶: Returns the x, y and z component of this vector

get_y()¶

get_z()¶

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

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

static operator_delete()¶

Don’t inherit from MemoryBase directly to work around GCC<10.1 bug.

static operator_delete()¶

Don’t inherit from MemoryBase directly to work around GCC<10.1 bug.

static operator_new()¶

Don’t inherit from MemoryBase directly to work around GCC<10.1 bug.

static operator_new()¶

Don’t inherit from MemoryBase directly to work around GCC<10.1 bug.

output()¶

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_w()¶

set_x()¶

set_y()¶

set_z()¶

static size()¶

static unit_w()¶: Returns a unit W vector.

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

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

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

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