Camera FOV

Other Standards COLLADA
1

Hi,

The COLLADA spec states:

The <perspective> element must contain either a single <xfov> element, a single <yfov> element, both <xfov> and <yfov> elements, or one of <xfov> or <yfov> and the <aspect_ratio> element. These describe the field of view of the camera.

What should I be doing if only an <xfov> or <yfov> element are specified? Should I assume a default aspect ratio?

Thanks,
David

This means that the application can calculate camera aspect ratio based on the viewport aspect ratio.
