LVecBase2f LVecBase2f::LVecBase2f(void); Filename: lvecBase2_src.I Created by: drose (08Mar00) PANDA 3D SOFTWARE Copyright (c) Carnegie Mellon University. All rights reserved. All use of this software is subject to the terms of the revised BSD license. You should have received a copy of this license along with this source code in a file named "LICENSE." Description:

addHash unsigned int LVecBase2f::add_hash(unsigned int hash) const; Description: Adds the vector into the running hash.

addToCell void LVecBase2f::add_to_cell(int i, float value); 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: Description:

addX void LVecBase2f::add_x(float value); 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: Description:

addY void LVecBase2f::add_y(float value); Description:

almostEqual bool LVecBase2f::almost_equal(LVecBase2f const &other, float threshold) const; Description: Returns true if two vectors are memberwise equal within a specified tolerance. Description: Returns true if two vectors are memberwise equal within a default tolerance based on the numeric type.

compareTo int LVecBase2f::compare_to(LVecBase2f const &other) const; Description: This flavor of compare_to uses a default threshold value based on the numeric type. Description: 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).

dot float LVecBase2f::dot(LVecBase2f const &other) const; Description:

fill void LVecBase2f::fill(float fill_value); Description: Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero.

fmax LVecBase2f LVecBase2f::fmax(LVecBase2f const &other); Description:

fmin LVecBase2f LVecBase2f::fmin(LVecBase2f const &other); Description:

getCell float LVecBase2f::get_cell(int i) const; Description:

getClassType static TypeHandle LVecBase2f::get_class_type(void); Undocumented function.

getData float const *LVecBase2f::get_data(void) const; Description: Returns the address of the first of the two data elements in the vector. The next element occupies the next position consecutively in memory.

getHash unsigned int LVecBase2f::get_hash(void) const; Description: Returns a suitable hash for phash_map.

getNumComponents int LVecBase2f::get_num_components(void) const; Description: Returns the number of elements in the vector, two.

getX float LVecBase2f::get_x(void) const; Description:

getY float LVecBase2f::get_y(void) const; Description:

isNan bool LVecBase2f::is_nan(void) const; Description: Returns true if any component of the vector is not-a-number, false otherwise.

length float LVecBase2f::length(void) const; Description: Returns the length of the vector, by the Pythagorean theorem.

lengthSquared float LVecBase2f::length_squared(void) const; Description: Returns the square of the vector's length, cheap and easy.

normalize bool LVecBase2f::normalize(void); Description: Normalizes the vector in place. Returns true if the vector was normalized, false if it was a zero-length vector.

operator != bool LVecBase2f::operator !=(LVecBase2f const &other) const; Description:

operator * LVecBase2f LVecBase2f::operator *(float scalar) const; Description:

operator *= void LVecBase2f::operator *=(float scalar); Description:

operator + LVecBase2f LVecBase2f::operator +(LVecBase2f const &other) const; Description:

operator += void LVecBase2f::operator +=(LVecBase2f const &other); Description:

operator - LVecBase2f LVecBase2f::operator -(LVecBase2f const &other) const; Description:

operator - LVecBase2f LVecBase2f::operator -(LVecBase2f const &other) const; Description:

operator -= void LVecBase2f::operator -=(LVecBase2f const &other); Description:

operator / LVecBase2f LVecBase2f::operator /(float scalar) const; Description:

operator /= void LVecBase2f::operator /=(float scalar); Description:

operator < bool LVecBase2f::operator <(LVecBase2f const &other) const; Description: This performs a lexicographical comparison. It's of questionable mathematical meaning, but sometimes has a practical purpose for sorting unique vectors, especially in an STL container. Also see compare_to().

operator = LVecBase2f &LVecBase2f::operator =(LVecBase2f const &copy); Description:

operator == bool LVecBase2f::operator ==(LVecBase2f const &other) const; Description:

operator [] float LVecBase2f::operator [](int i) const; Description:

operator delete void LVecBase2f::operator delete(void *ptr); Undocumented function.

operator new void *LVecBase2f::operator new(unsigned int size); Undocumented function.

output void LVecBase2f::output(ostream &out) const; Description:

project LVecBase2f LVecBase2f::project(LVecBase2f const &onto) const; Description: Returns a new vector representing the projection of this vector onto another one. The resulting vector will be a scalar multiple of onto.

pythonRepr void LVecBase2f::python_repr(ostream &out, string const &class_name) const; Description:

set void LVecBase2f::set(float x, float y); Description:

setCell void LVecBase2f::set_cell(int i, float value); Description:

Setitem void LVecBase2f::__setitem__(int i, float v); Description:

setX void LVecBase2f::set_x(float value); Description:

setY void LVecBase2f::set_y(float value); Description:

size static int LVecBase2f::size(void); HAVE_PYTHON Description: Returns 2: the number of components of a LVecBase2.

unitX static LVecBase2f const &LVecBase2f::unit_x(void); Description: Returns a unit X vector.

unitY static LVecBase2f const &LVecBase2f::unit_y(void); Description: Returns a unit Y vector.

validatePtr static bool LVecBase2f::validate_ptr(void const *ptr); Undocumented function.

zero static LVecBase2f const &LVecBase2f::zero(void); Description: Returns a zero-length vector.
