#[repr(C)]pub struct DVec3x2 {
    pub x: f64x2,
    pub y: f64x2,
    pub z: f64x2,
}

Expand description

A set of three coordinates which may be interpreted as a point or vector in 3d space, or as a homogeneous 2d vector or point.

Generally this distinction between a point and vector is more of a pain than it is worth to distinguish on a type level, however when converting to and from homogeneous coordinates it is quite important.

Fields

x: f64x2y: f64x2z: f64x2

Implementations

`impl DVec3x2`[src]

`pub const fn new(x: f64x2, y: f64x2, z: f64x2) -> Self`[src]

`pub const fn broadcast(val: f64x2) -> Self`[src]

`pub fn unit_x() -> Self`[src]

`pub fn unit_y() -> Self`[src]

`pub fn unit_z() -> Self`[src]

`pub fn into_homogeneous_point(self) -> DVec4x2`[src]

Create a homogeneous 3d point from this vector interpreted as a point, meaning the homogeneous component will start with a value of 1.0.

`pub fn into_homogeneous_vector(self) -> DVec4x2`[src]

Create a homogeneous 3d vector from this vector, meaning the homogeneous component will always have a value of 0.0.

`pub fn from_homogeneous_point(v: DVec4x2) -> Self`[src]

Create a 3d point from a homogeneous 3d point, performing division by the homogeneous component. This should not be used for homogeneous 3d vectors, which will have 0 as their homogeneous component.

`pub fn from_homogeneous_vector(v: DVec4x2) -> Self`[src]

Create a 3d vector from homogeneous 2d vector, which simply discards the homogeneous component.

`pub fn dot(&self, other: DVec3x2) -> f64x2`[src]

`pub fn wedge(&self, other: DVec3x2) -> DBivec3x2`[src]

The wedge (aka exterior) product of two vectors.

This operation results in a bivector, which represents the plane parallel to the two vectors, and which has a ‘oriented area’ equal to the parallelogram created by extending the two vectors, oriented such that the positive direction is the one which would move self closer to other.

`pub fn geom(&self, other: DVec3x2) -> DRotor3x2`[src]

The geometric product of this and another vector, which is defined as the sum of the dot product and the wedge product.

This operation results in a ‘rotor’, named as such as it may define a rotation. The rotor which results from the geometric product will rotate in the plane parallel to the two vectors, by twice the angle between them and in the opposite direction (i.e. it will rotate in the direction that would bring other towards self, and rotate in that direction by twice the angle between them).

`pub fn rotate_by(&mut self, rotor: DRotor3x2)`[src]

`pub fn rotated_by(self, rotor: DRotor3x2) -> Self`[src]

#[must_use = "Did you mean to use `.normalize()` to normalize `self` in place?"] pub fn normalized(&self) -> Self [src]

`pub fn normalize_homogeneous_point(&mut self)`[src]

Normalize self in-place by interpreting it as a homogeneous point, i.e. scaling the vector to ensure the homogeneous component has length 1.

#[must_use = "Did you mean to use `.normalize_homogeneous_point()` to normalize `self` in place?"] pub fn normalized_homogeneous_point(&self) -> Self [src]

`pub fn as_mut_slice(&mut self) -> &mut [f64x2]`[src]

`pub fn as_mut_byte_slice(&mut self) -> &mut [u8]`[src]

`pub const fn as_ptr(&self) -> *const f64x2`[src]

Returns a constant unsafe pointer to the underlying data in the underlying type. This function is safe because all types here are repr(C) and can be represented as their underlying type.

Safety

It is up to the caller to correctly use this pointer and its bounds.

`pub fn as_mut_ptr(&mut self) -> *mut f64x2`[src]

Returns a mutable unsafe pointer to the underlying data in the underlying type. This function is safe because all types here are repr(C) and can be represented as their underlying type.

Safety

`pub fn splat(vec: DVec3) -> Self`[src]

`pub fn blend(mask: m64x2, tru: Self, fals: Self) -> Self`[src]

Blend two vectors together lanewise using mask as a mask.

This is essentially a bitwise blend operation, such that any point where there is a 1 bit in mask, the output will put the bit from tru, while where there is a 0 bit in mask, the output will put the bit from fals

`impl Lerp<f64x2> for DVec3x2`[src]

Linearly interpolate between self and end by t between 0.0 and 1.0. i.e. (1.0 - t) * self + (t) * end.

For interpolating Rotors with linear interpolation, you almost certainly want to normalize the returned Rotor. For example,

let interpolated_rotor = rotor1.lerp(rotor2, 0.5).normalized();

For most cases (especially where performance is the primary concern, like in animation interpolation for games, this ‘normalized lerp’ or ‘nlerp’ is probably what you want to use. However, there are situations in which you really want the interpolation between two Rotors to be of constant angular velocity. In this case, check out Slerp.
