LVecBase2d.add_hash()

Adds the vector into the running hash.

Adds the vector into the running hash.

LVecBase2d.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:

LVecBase2d.add_x()
LVecBase2d.add_y()
LVecBase2d.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.

LVecBase2d.assign()
LVecBase2d.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).

LVecBase2d.componentwise_mult()
LVecBase2d.dot()
LVecBase2d.fill()

Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.

LVecBase2d.fmax()
LVecBase2d.fmin()
LVecBase2d.generate_hash()

Adds the vector to the indicated hash generator.

Adds the vector to the indicated hash generator.

LVecBase2d.get_cell()
static LVecBase2d.get_class_type()
static LVecBase2d.get_data()

Returns the address of the first of the two data elements in the vector. The next element occupies the next position consecutively in memory.

LVecBase2d.get_hash()

Returns a suitable hash for phash_map.

Returns a suitable hash for phash_map.

static LVecBase2d.get_num_components()
LVecBase2d.get_x()
LVecBase2d.get_y()
LVecBase2d.is_nan()

Returns true if any component of the vector is not-a-number, false otherwise.

LVecBase2d.length()

Returns the length of the vector, by the Pythagorean theorem.

LVecBase2d.length_squared()

Returns the square of the vector’s length, cheap and easy.

LVecBase2d.normalize()

Normalizes the vector in place. Returns true if the vector was normalized, false if it was a zero-length vector.

LVecBase2d.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 LVecBase2d.operator_delete()
static LVecBase2d.operator_delete()
static LVecBase2d.operator_new()
static LVecBase2d.operator_new()
LVecBase2d.output()
LVecBase2d.project()

Returns a new vector representing the projection of this vector onto another one. The resulting vector will be a scalar multiple of onto.

LVecBase2d.read_datagram()

Reads the vector from the Datagram using get_stdfloat().

LVecBase2d.read_datagram_fixed()

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

LVecBase2d.set()
LVecBase2d.set_cell()
LVecBase2d.set_x()
LVecBase2d.set_y()
static LVecBase2d.size()
static LVecBase2d.unit_x()

Returns a unit X vector.

static LVecBase2d.unit_y()

Returns a unit Y vector.

static LVecBase2d.validate_ptr()
LVecBase2d.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.

LVecBase2d.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 LVecBase2d.zero()

Returns a zero-length vector.
