Common Camera Parameters

This <extra> at the <camera> level includes common camera parameters supported directly by the FCollada library and used within ColladaMaya. These parameters are common to both perspective and orthographic types of camera. In 3.04, these parameters will be moved to the MAYA profile.

Element	Attributes supported	Description
<horizontal_aperture>	sid	Contains one floating point value: the horizontal size, in centimeters, of the camera lens. This element's contents can be animated using the 'sid' attribute. Moved to the MAYA profile in 3.04
<lens_squeeze>	sid	Contains one floating point value: a multiplicative factor for the horizontal size of the camera lens. This element's contents can be animated using the 'sid' attribute. Moved to the MAYA profile in 3.04
<vertical_aperture>	sid	Contains one floating point value: the vertical size, in centimeters, of the camera lens. This element's contents can be animated using the 'sid' attribute. Moved to the MAYA profile in 3.04
