Create a hierarchical model of the object in figure composed of four cylinders connected at the end.

You have available the geometric primitive DrawCylinder$($float r$,$ float h$),$ which draws a cylinder of

radius r and height h$,$ whose center is the origin and where the height is along the x axis. Write a

pseudo code that draws Figure $2$ by moving from the position in Figure $1$ to the position in Figure $2.$

$($Hint: use a chain of matrix multiplications$)$Figure $1.$

Figure $2.$

The other functions you may need are:

glRotate$($angle$,$ axisx, axisy, axisz$)$

glTranslate$($dx$,$dy$,$dz$)$

glPushMatrix$()$

glPopMatrix$()$
