The physical camera is a primitive meant to be a target for construction of
a physical camera model through applied, and multiply applied schemas.
The physical camera is a GeomXformable, and thus inherits the transform
schema. The physical camera also inherits the UsdGeomImageable schema,
which provides facilities for controlling visibility and rendering of the
camera.
The physical camera provides a number of attributes that are meant to be
authored by a user or by a DCC import process. These attributes are
generally meant to be authored once, and then left alone.
The concept is that the PhysicalCamera is just like a real camera that may
be used and measure on a real life stage, and it's attributes recorded in
a usd file. A real camera is a body, with a lens, and a film back, all
interchangeable, and these concepts are reflected in the proposed schema.
Physical Cameras for USD
On behalf of the Cameras in USD Working Group:
This schema usefully bridges the description of physical cameras to USD scenes.
