konstantin magnus Posted October 5, 2016 Share Posted October 5, 2016 matrix3 mat = ident(); vector axis = {0,1,0}; float angle = relbbox(0, @P).y; rotate(mat, angle, axis); @P *= mat; rotate is a function that changes a matrix. you need to multiply the changed matrix with your point positions to actually rotate your geometry.
