Struct Camera 

pub struct Camera { /* private fields */ }

A 2D camera that can be zoomed and panned.

Implementations

impl PanZoomCamera2d

pub fn new(eye: Vec2, zoom: f32) -> PanZoomCamera2d

Create a new arc-ball camera.

pub fn at(&self) -> Vec2

The point the arc-ball is looking at.

pub fn set_at(&mut self, at: Vec2)

Get a mutable reference to the point the camera is looking at.

pub fn zoom(&self) -> f32

Gets the zoom of the camera.

pub fn set_zoom(&mut self, zoom: f32)

Sets the zoom of the camera.

pub fn zoom_step(&self) -> f32

Gets the zoom step of the camera.

pub fn set_zoom_step(&mut self, new_zoom_step: f32)

Sets the zoom step of the camera.

pub fn look_at(&mut self, at: Vec2, zoom: f32)

Move the camera such that it is centered on a specific point.

pub fn drag_button(&self) -> Option<MouseButton>

The button used to drag the PanZoomCamera2d camera.

pub fn rebind_drag_button(&mut self, new_button: Option<MouseButton>)

Set the button used to drag the PanZoomCamera2d camera. Use None to disable dragging.

pub fn drag_modifier(&self) -> Option<Modifiers>

The modifier used to drag the PanZoomCamera2d camera.

pub fn rebind_drag_modifier(&mut self, new_modifier: Option<Modifiers>)

Set the modifier used to drag the PanZoomCamera2d camera.

pub fn zoom_modifier(&self) -> Option<Modifiers>

The modifier used to zoom the PanZoomCamera2d camera.

pub fn rebind_zoom_modifier(&mut self, new_modifier: Option<Modifiers>)

Set the modifier used to zoom the PanZoomCamera2d camera.

Trait Implementations

impl Camera2d for PanZoomCamera2d

fn unproject(&self, window_coord: Vec2, size: Vec2) -> Vec2

Calculate the global position of the given window coordinate

fn handle_event(&mut self, canvas: &Canvas, event: &WindowEvent)

Handles window events to update camera state.

fn view_transform_pair(&self) -> (Mat3, Mat3)

Returns the view and projection matrices for 2D rendering.

fn update(&mut self, _: &Canvas)

Updates the camera state for the current frame.

impl Clone for PanZoomCamera2d

fn clone(&self) -> PanZoomCamera2d

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PanZoomCamera2d

impl Debug for PanZoomCamera2d

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

Formats the value using the given formatter.

impl Default for PanZoomCamera2d

fn default() -> PanZoomCamera2d

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PanZoomCamera2d

fn deserialize<__D>( __deserializer: __D, ) -> Result<PanZoomCamera2d, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PanZoomCamera2d

fn eq(&self, other: &PanZoomCamera2d) -> 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 PanZoomCamera2d

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
