Enum trackball::Fixed

pub enum Fixed<N: Copy + RealField> {
    Hor(N),
    Ver(N),
    Upp(N),
}

Fixed quantity wrt field of view.

• Implements Default and can be created with Fixed::default() returning Fixed::Ver(N::frac_pi_4()).
• Implements From<N> and can be created with N::into() returning Fixed::Ver().

Variants

Hor(N)

Fixed horizontal field of view aka Vert- scaling.

Ver(N)

Fixed vertical field of view aka Hor+ scaling.

Upp(N)

Fixed unit per pixel on focus plane at distance from eye of one aka Pixel-based scaling.

Implementations

impl<N: Copy + RealField> Fixed<N>

pub fn to_hor(self, max: &Point2<N>) -> Self

Converts to fixed horizontal field of view wrt maximum position in screen space.

pub fn to_ver(self, max: &Point2<N>) -> Self

Converts to fixed vertical field of view wrt maximum position in screen space.

pub fn to_upp(self, max: &Point2<N>) -> Self

Converts to fixed unit per pixel on focus plane at distance from eye of one wrt maximum position in screen space.

pub fn max_and_upp(&self, zat: N, max: &Point2<N>) -> (Point2<N>, N)

Maximum position in camera space and unit per pixel on focus plane wrt distance between eye and target and maximum position in screen space.

pub const fn into_inner(self) -> N

Underlying quantity.

pub fn cast<M: Copy + RealField>(self) -> Fixed<M>

where N: SubsetOf<M>,

Casts components to another type, e.g., between f32 and f64.

Trait Implementations

impl<N: Copy + RealField> Archive for Fixed<N>

Available on crate feature rkyv only.

type Archived = Fixed<N>

The archived representation of this type.

type Resolver = ()

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve(&self, _: usize, (): Self::Resolver, out: *mut Self::Archived)

Creates the archived version of this value at the given position and writes it to the given output.

impl<N: Clone + Copy + RealField> Clone for Fixed<N>

fn clone(&self) -> Fixed<N>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<N: Debug + Copy + RealField> Debug for Fixed<N>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<N: Copy + RealField> Default for Fixed<N>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, N> Deserialize<'de> for Fixed<N>

where N: Deserialize<'de> + Copy + RealField,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<De: Fallible + ?Sized, N: Copy + RealField> Deserialize<Fixed<N>, De> for Fixed<N>

Available on crate feature rkyv only.

fn deserialize(&self, _: &mut De) -> Result<Self, De::Error>

Deserializes using the given deserializer

impl<N: Copy + RealField> From<N> for Fixed<N>

fn from(fov: N) -> Self

Converts to this type from the input type.

impl<N: PartialEq + Copy + RealField> PartialEq for Fixed<N>

fn eq(&self, other: &Fixed<N>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Ser: Fallible + ?Sized, N: Copy + RealField> Serialize<Ser> for Fixed<N>

Available on crate feature rkyv only.

fn serialize(&self, _: &mut Ser) -> Result<Self::Resolver, Ser::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.

impl<N> Serialize for Fixed<N>

where N: Serialize + Copy + RealField,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<N: Copy + Copy + RealField> Copy for Fixed<N>

impl<N: Eq + Copy + RealField> Eq for Fixed<N>

impl<N: Copy + RealField> StructuralPartialEq for Fixed<N>
