Struct cxx_qt_lib::QVector3D

#[repr(C)]
pub struct QVector3D { /* private fields */ }

The QVector3D class represents a vector or vertex in 3D space.

Implementations

impl QVector3D

pub fn is_null(&self) -> bool

Returns true if the x, y, and z coordinates are set to 0.0, otherwise returns false.

impl QVector3D

pub fn length(&self) -> f32

Returns the length of the vector from the origin.

impl QVector3D

pub fn length_squared(&self) -> f32

Returns the squared length of the vector from the origin. This is equivalent to the dot product of the vector with itself.

impl QVector3D

pub fn normalize(&mut self)

Normalizes the currect vector in place. Nothing happens if this vector is a null vector or the length of the vector is very close to 1.

impl QVector3D

pub fn normalized(&self) -> QVector3D

Returns the normalized unit vector form of this vector.

If this vector is null, then a null vector is returned. If the length of the vector is very close to 1, then the vector will be returned as-is. Otherwise the normalized form of the vector of length 1 will be returned.

impl QVector3D

pub fn set_x(&mut self, x: f32)

Sets the x coordinate of this point to the given finite x coordinate.

impl QVector3D

pub fn set_y(&mut self, y: f32)

Sets the y coordinate of this point to the given finite y coordinate.

impl QVector3D

pub fn set_z(&mut self, z: f32)

Sets the z coordinate of this point to the given finite z coordinate.

impl QVector3D

pub fn x(&self) -> f32

Returns the x coordinate of this point.

impl QVector3D

pub fn y(&self) -> f32

Returns the y coordinate of this point.

impl QVector3D

pub fn z(&self) -> f32

Returns the z coordinate of this point.

impl QVector3D

pub fn new(xpos: f32, ypos: f32, zpos: f32) -> Self

Constructs a vector with coordinates (xpos, ypos, zpos). All parameters must be finite.

pub fn distance_to_line(&self, point: QVector3D, direction: QVector3D) -> f32

Returns the distance that this vertex is from a line defined by point and the unit vector direction.

If direction is a null vector, then it does not define a line. In that case, the distance from point to this vertex is returned.

pub fn distance_to_plane(&self, point: QVector3D, normal: QVector3D) -> f32

Returns the distance from this vertex to a plane defined by the vertex plane and a normal unit vector. The normal parameter is assumed to have been normalized to a unit vector.

The return value will be negative if the vertex is below the plane, or zero if it is on the plane.

pub fn distance_to_point(&self, point: QVector3D) -> f32

Returns the distance from this vertex to a point defined by the vertex point.
