Implementations

impl Camera

pub fn new() -> Self

Create a new camera with default 3D settings

pub fn new_2d(bounds: (f32, f32, f32, f32)) -> Self

Create a 2D orthographic camera for 2D plotting

pub fn update_aspect_ratio(&mut self, aspect_ratio: f32)

Update aspect ratio (call when window resizes)

pub fn view_proj_matrix(&mut self) -> Mat4

Get the view-projection matrix

pub fn mark_dirty(&mut self)

Mark the camera matrices as dirty (call after manually modifying projection)

pub fn view_matrix(&mut self) -> Mat4

Get the view matrix

pub fn projection_matrix(&mut self) -> Mat4

Get the projection matrix

pub fn pan(&mut self, delta: Vec2)

Pan the camera (screen-space movement)

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

Zoom the camera (positive = zoom in, negative = zoom out)

pub fn rotate(&mut self, delta: Vec2)

Rotate the camera around the target (for 3D)

pub fn look_at(&mut self, target: Vec3, distance: Option<f32>)

Set camera to look at a specific target

pub fn reset(&mut self)

Reset camera to default position

pub fn fit_bounds(&mut self, min_bounds: Vec3, max_bounds: Vec3)

Fit the camera to show all data within the given bounds

pub fn screen_to_world( &self, screen_pos: Vec2, screen_size: Vec2, depth: f32, ) -> Vec3

Convert screen coordinates to world coordinates (for picking)

Trait Implementations

impl Clone for Camera

fn clone(&self) -> Camera

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 Default for Camera

fn default() -> Self

Returns the “default value” for a type.
