LVecBase3f

Inheritance:

Methods of LVecBase3f:

addHash
unsigned int LVecBase3f::add_hash(unsigned int hash) const;

Description: Adds the vector into the running hash.

addToCell
void LVecBase3f::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 LVecBase3f::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 LVecBase3f::add_y(float value);

Description:

addZ
void LVecBase3f::add_z(float value);

Description:

almostEqual
bool LVecBase3f::almost_equal(LVecBase3f 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 LVecBase3f::compare_to(LVecBase3f 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).

cross
LVecBase3f LVecBase3f::cross(LVecBase3f const &other) const;

Description:

crossInto
void LVecBase3f::cross_into(LVecBase3f const &other);

Description:

dot
float LVecBase3f::dot(LVecBase3f const &other) const;

Description:

fill
void LVecBase3f::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
LVecBase3f LVecBase3f::fmax(LVecBase3f const &other);

Description:

fmin
LVecBase3f LVecBase3f::fmin(LVecBase3f const &other);

Description:

getCell
float LVecBase3f::get_cell(int i) const;

Description:

getClassType
static TypeHandle LVecBase3f::get_class_type(void);

Undocumented function.

getData
float const *LVecBase3f::get_data(void) const;

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

getHash
unsigned int LVecBase3f::get_hash(void) const;

Description: Returns a suitable hash for phash_map.

getNumComponents
int LVecBase3f::get_num_components(void) const;

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

getStandardizedHpr
LVecBase3f LVecBase3f::get_standardized_hpr(void) const;

Description: Try to un-spin the hpr to a standard form. Like all standards, someone decides between many arbitrary posible standards. This function assumes that 0 and 360 are the same, as is 720 and
-360. Also 180 and -180 are the same. Another
example is -90 and 270. Each element will be in the range -180.0 to 179.99999. The original usage of this function is for human readable output.
It doesn't work so well for asserting that foo_hpr is roughly equal to bar_hpr. Try using LQuaternionf::is_same_direction() for that. See Also: get_standardized_rotation, LQuaternion::is_same_direction

getX
float LVecBase3f::get_x(void) const;

Description:

getY
float LVecBase3f::get_y(void) const;

Description:

getZ
float LVecBase3f::get_z(void) const;

Description:

isNan
bool LVecBase3f::is_nan(void) const;

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

length
float LVecBase3f::length(void) const;

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

lengthSquared
float LVecBase3f::length_squared(void) const;

Description: Returns the square of the vector's length, cheap and easy.

normalize
bool LVecBase3f::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 LVecBase3f::operator !=(LVecBase3f const &other) const;
