Struct Camera 

pub struct Camera {
    pub intrinsic: Projection,
    pub extrinsic: CameraExtrinsic,
}

Combination of camera projection and extrinsic pose. Port of Camera.

Fields

intrinsic: Projection

extrinsic: CameraExtrinsic

Implementations

impl Camera

pub fn new( fovy: f32, near: f32, far: f32, size: (f32, f32), position: Vec3, direction: Vec3, up: Vec3, ) -> Self

A perspective camera, matching silx Camera defaults (fovy 30°).

pub fn matrix(&self) -> Mat4

The full clip-space matrix projection · view.

pub fn set_size(&mut self, size: (f32, f32))

Update the viewport size used for the projection aspect ratio.

pub fn reset_camera(&mut self, bounds: (Vec3, Vec3))

Position the camera so the axes-aligned bounds fit the frustum, and set the near/far depth extent to bracket them. Sight direction and up are preserved. Port of Camera.resetCamera.

pub fn size(&self) -> (f32, f32)

Current viewport size used for the projection.

pub fn pan(&mut self, from_ndc: Vec3, to_ndc: Vec3)

Pan: translate the camera so the scene point under from_ndc moves to to_ndc, both NDC positions sharing a fixed z (the pan plane). Port of CameraSelectPan.drag — un-projects both NDC points to scene space through the inverse camera matrix and shifts the camera by their difference. A no-op if the camera matrix is singular.

pub fn zoom_at(&mut self, ndc: (f32, f32), ndc_z: f32, zoom_in: bool)

Zoom keeping the point under the cursor invariant. Port of CameraWheel._zoomToPosition: for a perspective camera, move the camera toward/away from the un-projected cursor point; for orthographic, widen or narrow the clip rectangle around the cursor. ndc is the cursor in NDC, ndc_z the cursor’s pan-plane depth (perspective only), zoom_in true to move closer.

pub fn adjust_depth_extent(&mut self, bounds: (Vec3, Vec3))

Update only the near/far depth extent so axis-aligned bounds stay inside the frustum. Port of Viewport.adjustCameraDepthExtent: transform the eight box corners into camera space and bracket their z-range. Sight direction, up and position are unchanged.
