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