LVecBase4f.add_hash()¶

Adds the vector into the running hash.

LVecBase4f.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:

LVecBase4f.add_w()¶

LVecBase4f.add_x()¶

LVecBase4f.add_y()¶

LVecBase4f.add_z()¶

LVecBase4f.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.

LVecBase4f.assign()¶

LVecBase4f.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).

LVecBase4f.componentwise_mult()¶

LVecBase4f.dot()¶

static LVecBase4f.extract_data()¶

LVecBase4f.fill()¶: Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.

LVecBase4f.fmax()¶

LVecBase4f.fmin()¶

LVecBase4f.generate_hash()¶

Adds the vector to the indicated hash generator.

LVecBase4f.get_cell()¶

static LVecBase4f.get_class_type()¶

static LVecBase4f.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.

LVecBase4f.get_hash()¶

Returns a suitable hash for phash_map.

static LVecBase4f.get_num_components()¶

LVecBase4f.get_w()¶

LVecBase4f.get_x()¶

LVecBase4f.get_xy()¶: Returns the x and y component of this vector

LVecBase4f.get_xyz()¶: Returns the x, y and z component of this vector

LVecBase4f.get_y()¶

LVecBase4f.get_z()¶

LVecBase4f.is_nan()¶: Returns true if any component of the vector is not-a-number, false otherwise.

LVecBase4f.length()¶: Returns the length of the vector, by the Pythagorean theorem.

LVecBase4f.length_squared()¶: Returns the square of the vector’s length, cheap and easy.

LVecBase4f.normalize()¶: Normalizes the vector in place. Returns true if the vector was normalized, false if it was a zero-length vector.

LVecBase4f.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 LVecBase4f.operator_delete()¶

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

static LVecBase4f.operator_delete()¶

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

static LVecBase4f.operator_new()¶

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

static LVecBase4f.operator_new()¶

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

LVecBase4f.output()¶

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

LVecBase4f.read_datagram()¶: Reads the vector from the Datagram using get_stdfloat().

LVecBase4f.read_datagram_fixed()¶: Reads the vector from the Datagram using get_float32() or get_float64(). See write_datagram_fixed().

LVecBase4f.set()¶

LVecBase4f.set_cell()¶

LVecBase4f.set_w()¶

LVecBase4f.set_x()¶

LVecBase4f.set_y()¶

LVecBase4f.set_z()¶

static LVecBase4f.size()¶

static LVecBase4f.unit_w()¶: Returns a unit W vector.

static LVecBase4f.unit_x()¶: Returns a unit X vector.

static LVecBase4f.unit_y()¶: Returns a unit Y vector.

static LVecBase4f.unit_z()¶: Returns a unit Z vector.

LVecBase4f.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.

LVecBase4f.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.

static LVecBase4f.zero()¶: Returns a zero-length vector.
