LVecBase4d

Inheritance:

Methods of LVecBase4d:

addHash
unsigned int LVecBase4d::add_hash(unsigned int hash) const;

Description: Adds the vector into the running hash.

addToCell
void LVecBase4d::add_to_cell(int i, double 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:

addW
void LVecBase4d::add_w(double value);

Description:

addX
void LVecBase4d::add_x(double 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 LVecBase4d::add_y(double value);

Description:

addZ
void LVecBase4d::add_z(double value);

Description:

almostEqual
bool LVecBase4d::almost_equal(LVecBase4d const &other, double 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 LVecBase4d::compare_to(LVecBase4d 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
double LVecBase4d::dot(LVecBase4d const &other) const;

Description:

fill
void LVecBase4d::fill(double fill_value);

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

getCell
double LVecBase4d::get_cell(int i) const;

Description:

getClassType
static TypeHandle LVecBase4d::get_class_type(void);

Undocumented function.

getData
double const *LVecBase4d::get_data(void) const;

Description: Returns the address of the first of the four data elements in the vector. The remaining elements occupy the next positions consecutively in memory.

getHash
unsigned int LVecBase4d::get_hash(void) const;

Description: Returns a suitable hash for phash_map.

getNumComponents
int LVecBase4d::get_num_components(void) const;

Description: Returns the number of elements in the vector, four.

getW
double LVecBase4d::get_w(void) const;

Description:

getX
double LVecBase4d::get_x(void) const;

Description:

getY
double LVecBase4d::get_y(void) const;

Description:

getZ
double LVecBase4d::get_z(void) const;

Description:

isNan
bool LVecBase4d::is_nan(void) const;

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

operator !=
bool LVecBase4d::operator !=(LVecBase4d const &other) const;

Description:

operator *
LVecBase4d LVecBase4d::operator *(double scalar) const;

Description:

operator *=
void LVecBase4d::operator *=(double scalar);

Description:

operator +
LVecBase4d LVecBase4d::operator +(LVecBase4d const &other) const;

Description:

operator +=
void LVecBase4d::operator +=(LVecBase4d const &other);

Description:

operator -
LVecBase4d LVecBase4d::operator -(void) const;

Description:

operator -=
void LVecBase4d::operator -=(LVecBase4d const &other);

Description:

operator /
LVecBase4d LVecBase4d::operator /(double scalar) const;

Description:

operator /=
void LVecBase4d::operator /=(double scalar);

Description:

operator <
bool LVecBase4d::operator <(LVecBase4d 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().
