# panda3d.core.LVector3d¶

class LVector3d

Bases: LVecBase3d

This is a three-component vector distance (as opposed to a three-component point, which represents a particular point in space). 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.

angleDeg(other: LVector3d) → float

Returns the angle between this vector and the other one, expressed in degrees. Both vectors should be initially normalized.

angleRad(other: LVector3d) → float

Returns the unsigned angle between this vector and the other one, expressed in radians. Both vectors should be initially normalized.

static back(cs: CoordinateSystem) → LVector3d

Returns the back vector for the given coordinate system.

getXy() → LVector2d

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

Return type

LVector2d

getXz() → LVector2d

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

Return type

LVector2d

getYz() → LVector2d

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

Return type

LVector2d

static left(cs: CoordinateSystem) → LVector3d

Returns the left vector for the given coordinate system.

Return type

LVector3d

normalized() → LVector3d

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.

Return type

LVector3d

project(onto: LVecBase3d) → LVector3d

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

Return type

LVector3d

relativeAngleDeg(other: LVector3d) → float

Deprecated: Do not use.

relativeAngleRad(other: LVector3d) → float

Deprecated: Do not use.

static rfu(right: float, fwd: float, up: float, cs: CoordinateSystem) → LVector3d

Returns a vector that is described by its right, forward, and up components, in whatever way the coordinate system represents that vector.

Return type

LVector3d

static right(cs: CoordinateSystem) → LVector3d

Returns the right vector for the given coordinate system.

Return type

LVector3d

signedAngleDeg(other: LVector3d, ref: LVector3d) → float

Returns the signed angle between two vectors. The angle is positive if the rotation from this vector to other is clockwise when looking in the direction of the ref vector.

Vectors (except the ref vector) should be initially normalized.

signedAngleRad(other: LVector3d, ref: LVector3d) → float

returns the signed angle between two vectors. The angle is positive if the rotation from this vector to other is clockwise when looking in the direction of the ref vector.

Vectors (except the ref vector) should be initially normalized.
