physicalWidth
An image’s width in centimeters.
Overview
This property informs the runtime how wide the image is in the physical environment. The runtime calculates the height based on the image’s aspect ratio.
Because this property describes a real-world width, the prim’s transform hierarchy doesn’t modify this property’s value.
Declaration
