[Feature]: Adjust Camera Coordinates: Make +Z Axis Represent Forward Direction

[solemnwind]

What feature or enhancement are you proposing?

Change the behavior of genesis.vis.camera.Camera(transform=T), so that T represents a transform where +z is the forward direction of the camera. (Or mention explicitly in the document that +z points backward to avoid confusion)

Motivation

Right now the camera uses pyrender (OpenGL) conventions, +z points the backward of the camera. However I believe in many cases people use +z to represent the forward direction of a camera.

Potential Benefit

Avoid confusion for people who think +z should align with the forward direction of the camera. Especially when they are using camera.attach() to attach a camera to some object, this proposed change could reduce confusion.

What is the expected outcome of the implementation work?

Either document the convention of camera frame we use;

Or make +z align with camera forward direction default/optional.
