Struct CameraView 

pub struct CameraView { /* private fields */ }

A camera view structure for visualizing camera poses.

Implementations

impl CameraView

pub fn new(name: impl Into<String>, params: CameraParameters) -> Self

Creates a new camera view from camera parameters.

pub fn from_look_at( name: impl Into<String>, position: Vec3, look_at: Vec3, up: Vec3, fov_vertical_degrees: f32, aspect_ratio: f32, ) -> Self

Creates a camera view with position and look direction.

pub fn params(&self) -> &CameraParameters

Gets the camera parameters.

pub fn set_params(&mut self, params: CameraParameters) -> &mut Self

Updates the camera parameters.

pub fn color(&self) -> Vec4

Gets the widget color.

pub fn set_color(&mut self, color: Vec3) -> &mut Self

Sets the widget color.

pub fn widget_focal_length(&self) -> f32

Gets the widget focal length (distance from camera origin to frame).

pub fn set_widget_focal_length( &mut self, length: f32, is_relative: bool, ) -> &mut Self

Sets the widget focal length.

pub fn widget_thickness(&self) -> f32

Gets the widget thickness (line/sphere radius relative to focal length).

pub fn set_widget_thickness(&mut self, thickness: f32) -> &mut Self

Sets the widget thickness.

pub fn needs_reinit(&self, length_scale: f32) -> bool

Returns true if geometry needs to be (re-)initialized because length_scale changed.

pub fn init_render_data( &mut self, device: &Device, bind_group_layout: &BindGroupLayout, camera_buffer: &Buffer, queue: &Queue, length_scale: f32, )

Initializes GPU render data.

pub fn render_data(&self) -> Option<&CurveNetworkRenderData>

Returns the render data if available.

pub fn take_fly_to_request(&mut self) -> bool

Returns true if the user has requested to fly to this camera view. The flag is automatically cleared after reading.

pub fn build_egui_ui(&mut self, ui: &mut Ui)

Builds the egui UI for this camera view.
