A camera is a set of several elements:
a sensor: a set of information concerning the rendering that is applied when the camera is used for viewing. Its modifiable settings include:
Sensor size / Aspect ratio,
Type of render (post-process, overlays, backgrounds),
Type of projection : isometric/perspective ,
a lens: information linked to the position of the object viewed in relation to the camera:
Focal distance / Field of view angle (FOVX or FOVY),
Depth of field (aperture, focal point distance),
a camera position: the position and the orientation of the camera.
Cameras are used to prepare rendering by setting up a particular view of a product in a viewport. This view can then be saved, recalled, or used to create films and images.
