Cameras

class yt_idv.cameras.base_camera.BaseCamera(**kwargs: Any)

Bases: HasTraits

Camera object used in the Interactive Data Visualization

Parameters:

• position (iterable, or 3 element array in code_length) – The initial position of the camera.

• focus (iterable, or 3 element array in code_length) – A point in space that the camera is looking at.

• up (iterable, or 3 element array in code_length) – The ‘up’ direction for the camera.

• fov (float, optional) – An angle defining field of view in degrees.

• near_plane (float, optional) – The distance to the near plane of the perspective camera.

• far_plane (float, optional) – The distance to the far plane of the perspective camera.

• aspect_ratio (float, optional) – The ratio between the height and the width of the camera’s fov.
