I've come across a need to position a camera for an arbitrary (unknown) scene. The camera can be updated later, but I thought I'd give it a reasonable default, and the thought crossed my mind that there may be a decent "standard" for this.
At the very least, a given modeling program (Maya, 3dsMax, blender...) ships with a default position / orientation for a camera.
A default light would be useful too; is there a similar standard for this?
In the lack of any good suggestions here, I thought I'd try to orient the camera so that an object of approximate diameter of 2 (such as a unit circle) would fit well in the scene and provide a directional light in the direction of the camera.
Edit: while we're at it, what about:
- camera FOV / frustum
- light color / intensity / etc
