# geometry parametric issue : find M in [tx-rx] defined as M = alpha*rx + (1-alpha)tx where alpha in [0-1]. # if alpha = 0 then M = tx ; if alpha = 1 then M = rx. # Besides, M is defined as M = pg + beta*uw + gamma*uh then alpha*rx + (1-alpha)tx = pg + beta*uw + gamma*uh # [rx-tx , -uw, -uh]*[alpha,beta,gamma].T = pg - tx <==> Ax = b solved by la.solve ; x[0]=alpha, x[1]=beta and
