Description:

operator =
LPoint2f &LPoint2f::operator =(LVecBase2f const &copy);

Description:

pythonRepr
void LPoint2f::python_repr(ostream &out, string const &class_name) const;

Description:

unitX
static LPoint2f const &LPoint2f::unit_x(void);

Description: Returns a unit X point.

unitY
static LPoint2f const &LPoint2f::unit_y(void);

Description: Returns a unit Y point.

zero
static LPoint2f const &LPoint2f::zero(void);

Description: Returns a zero-length point.

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.

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.

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 -(void) 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().
