Struct Camera 

pub struct Camera {
    pub eye: Vec3<f32>,
    pub target: Vec3<f32>,
    pub up: Vec3<f32>,
    pub projection: Projection,
}

Validated look-at camera.

Fields

eye: Vec3<f32>

Camera position in world coordinates.

target: Vec3<f32>

Look-at target in world coordinates.

up: Vec3<f32>

Approximate world-space up direction.

projection: Projection

Camera projection.

Implementations

impl Camera

pub fn try_new( eye: Vec3<f32>, target: Vec3<f32>, up: Vec3<f32>, projection: Projection, ) -> VizResult<Self>

Creates a validated look-at camera.

pub fn fit_perspective_bounds( min: Vec3<f32>, max: Vec3<f32>, view_direction: Vec3<f32>, up: Vec3<f32>, vertical_fov_radians: f32, aspect: f32, padding: f32, ) -> VizResult<Self>

Fits a perspective camera around finite axis-aligned bounds.

view_direction points from the eye toward the bounds center. padding must be at least one and expands the bounding sphere used for clipping.

Trait Implementations

impl Clone for Camera

fn clone(&self) -> Camera

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Camera

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Camera

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Camera

fn eq(&self, other: &Camera) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Camera

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Camera

impl StructuralPartialEq for Camera
