Functions
void	u_visibility_mask_get_default (enum xrt_visibility_mask_type type, const struct xrt_fov *fov, struct xrt_visibility_mask **out_mask)
	Default visibility mask, only returns a very simple mask with four small triangles in each corner, scaled to the given FoV so it matches the OpenXR conventions. More...
