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.

LPoint2f LPoint3f::get_xy

(

)

const [inline]

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

Reimplemented from LVecBase3f.

Definition at line 281 of file lpoint3.h.

LPoint2f LPoint3f::get_xz

(

)

const [inline]

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

Reimplemented from LVecBase3f.

Definition at line 292 of file lpoint3.h.

LPoint2f LPoint3f::get_yz

(

)

const [inline]

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

Reimplemented from LVecBase3f.

Definition at line 303 of file lpoint3.h.

LPoint3f LPoint3f::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 418 of file lpoint3.h.

LPoint3f LPoint3f::project

(

const LVecBase3f &

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 LVecBase3f.

LPoint3f LPoint3f::rfu	(	float	right,
		float	fwd,
		float	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.
