Hello!
I’ve made a PR proposal for adding back plate and eventually image plane support in USD along with introducing a Gaussian thin lens camera model to interact with these features. Back plates can be thought of as a texture card that’s rendered in the scene, wheres image planes refer to images pasted onto the camera sensor itself. More details can be found in the proposal below!
Feedback welcome in this thread, or on the PR directly.
Thanks!
Denise
