◆ BM_face_uv_calc_center_median_weighted()

void BM_face_uv_calc_center_median_weighted	(	const BMFace *	f,
		const float	aspect[2],
		int	cd_loop_uv_offset,
		float	r_cent[2] )

Computes the UV center of a face, using the mean average weighted by edge length.

See BM_face_calc_center_median_weighted for matching spatial functionality.

Parameters

aspect Calculate the center scaling by these values, and finally dividing. Since correct weighting depends on having the correct aspect.
