Detailed Description

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.

LPoint2d LPoint3d::get_xy

(

)

const [inline]

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

Reimplemented from LVecBase3d.

Definition at line 686 of file lpoint3.h.

LPoint2d LPoint3d::get_xz

(

)

const [inline]

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

Reimplemented from LVecBase3d.

Definition at line 697 of file lpoint3.h.

LPoint2d LPoint3d::get_yz

(

)

const [inline]

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

Reimplemented from LVecBase3d.

Definition at line 708 of file lpoint3.h.

LPoint3d LPoint3d::origin

(

CoordinateSystem

cs = CS_default

)

[inline, static]

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.

Definition at line 823 of file lpoint3.h.

LPoint3d LPoint3d::project

(

const LVecBase3d &

onto

)

const [inline]

Returns a new vector representing the projection of this vector onto another one.

The resulting vector will be a scalar multiple of onto.

Reimplemented from LVecBase3d.

Definition at line 790 of file lpoint3.h.

LPoint3d LPoint3d::rfu	(	double	right,
		double	fwd,
		double	up,
		CoordinateSystem	cs = CS_default
	)		[inline, static]

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

Definition at line 835 of file lpoint3.h.

const LPoint3d & LPoint3d::unit_x

(

)

[inline, static]

Returns a unit X point.

Reimplemented from LVecBase3d.

Definition at line 655 of file lpoint3.h.

const LPoint3d & LPoint3d::unit_y

(

)

[inline, static]

Returns a unit Y point.

Reimplemented from LVecBase3d.

Definition at line 665 of file lpoint3.h.

const LPoint3d & LPoint3d::unit_z

(

)

[inline, static]

Returns a unit Z point.

Reimplemented from LVecBase3d.

Definition at line 675 of file lpoint3.h.

const LPoint3d & LPoint3d::zero

(

)

[inline, static]

Returns a zero-length point.

Reimplemented from LVecBase3d.
