origin static LPoint3d LPoint3d::origin(CoordinateSystem cs = (CS_default)); Some special named constructors for LPoint3. Description: Returns the origin of the indicated coordinate system. This is always 0, 0, 0 with all of our existing coordinate systems; it's hard to imagine it ever being different. |

addHash unsigned int LVecBase3d::add_hash(unsigned int hash) const; Description: Adds the vector into the running hash. |
addToCell void LVecBase3d::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: |
addX void LVecBase3d::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: |

addZ void LVecBase3d::add_z(double value); Description: |
almostEqual bool LVecBase3d::almost_equal(LVecBase3d 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 LVecBase3d::compare_to(LVecBase3d 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). |

fill void LVecBase3d::fill(double fill_value); Description: Sets each element of the vector to the indicated fill_value. This is particularly useful for initializing to zero. |

getClassType static TypeHandle LVecBase3d::get_class_type(void); Undocumented function. |
getData double const *LVecBase3d::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 LVecBase3d::get_hash(void) const; Description: Returns a suitable hash for phash_map. |
getNumComponents int LVecBase3d::get_num_components(void) const; Description: Returns the number of elements in the vector, three. |
getStandardizedHpr LVecBase3d LVecBase3d::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 |
