Module camera 

Camera: projection (intrinsic) × position/orientation (extrinsic).

A port of silx silx.gui.plot3d.scene.camera. silx caches matrices behind a change-notifier; here every matrix is rebuilt on demand (a 4×4 build per frame is negligible), so the observer machinery is dropped.

Structs

Camera

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

CameraExtrinsic

Camera position and orientation (the view matrix). Port of CameraExtrinsic.

Orthographic

Orthographic projection with optional aspect-ratio preservation. Port of transform.Orthographic.

Perspective

Perspective projection by field-of-view + aspect. Port of transform.Perspective.

Enums

CameraDirection

Rotation direction relative to the image plane, for CameraExtrinsic::orbit and CameraExtrinsic::rotate. Mirrors silx’s 'up'/'down'/'left'/'right'.

CameraFace

Pre-defined camera orientations, for CameraExtrinsic::reset. Mirrors _RESET_CAMERA_ORIENTATIONS.

CameraMove

Translation direction relative to the image plane, for CameraExtrinsic::move_to. Mirrors silx’s six move directions.

Projection

Camera intrinsic: either perspective or orthographic projection.
