LPoint3d

class LPoint3d

Bases: LVecBase3d

This is a three-component point in space (as opposed to a three-component vector, which represents a direction and a distance). Some of the methods are slightly different between LPoint3 and LVector3; in particular, subtraction of two points yields a vector, while addition of a vector and a point yields a point.

LPoint3d(void) = default
LPoint3d(LVecBase3d const &copy)
LPoint3d(double fill_value)
LPoint3d(double x, double y, double z)
LPoint3d(LVecBase2d const &copy, double z)
LPoint3d(LPoint3d const&) = default
LPoint3d cross(LVecBase3d const &other) const
static TypeHandle get_class_type(void)
LPoint2d get_xy(void) const

Returns a 2-component vector that shares just the first two components of this vector.

LPoint2d get_xz(void) const

Returns a 2-component vector that shares just the first and last components of this vector.

LPoint2d get_yz(void) const

Returns a 2-component vector that shares just the last two components of this vector.

LPoint3d normalized(void) const

Normalizes the vector and returns the normalized vector as a copy. If the vector was a zero-length vector, a zero length vector will be returned.

LPoint3d const &origin(CoordinateSystem cs = ::CS_default)

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.

LPoint3d project(LVecBase3d const &onto) const

Returns a new vector representing the projection of this vector onto another one. The resulting vector will be a scalar multiple of onto.

LPoint3d rfu(double right, double fwd, double up, CoordinateSystem cs = ::CS_default)

Returns a point described by right, forward, up displacements from the origin, wherever that maps to in the given coordinate system.

LPoint3d const &unit_x(void)

Returns a unit X point.

LPoint3d const &unit_y(void)

Returns a unit Y point.

LPoint3d const &unit_z(void)

Returns a unit Z point.

LPoint3d const &zero(void)

Returns a zero-length point.
