It doesn’t look like the information on morph rotation is correct
any longer - exercises 7.3 and 7.4 and the associated text around
that on page 115.</blockquote>
<p>I see.</p>
<p>I have not checked it yet, I remember discussing with Juan about
the possibility to alter the center of rotation.<br>
</p>
<p>Juan will it not be better to keep it backward compatible: if not
specified the center of rotation will be (0;0)?<br>

<div>When I rotate any of the example morphs from this chapter -
the line/cross, triangle and the rectangle - they all rotate
about the centre and not the 0@0 point; this includes the
triangle, which is fun to see.</div>
<div><br>
</div>
<div>I’ve had a little dig through the morph handle code - just
enough to be potentially wrong - and it seems that if a rotation
centre isn’t specified then one is computed to be the middle of
the morph bounds.</div>
<div><br>
</div>
<div>Finally a really tiny typo - in section 6.2.2, first sentence
of third paragraph it reads:</div>
<div><span style="font-family: CMR10; font-size: 11pt;"><br>
</span></div>
<div><span class="Apple-tab-span" style="white-space: pre;"> </span>So
far in our model, a torpedo is not subjected to the <i>central
<span style="font-family: CMR10; font-size: 11pt;">start</span></i><span
style="font-family: CMR10; font-size: 11pt;"><i> gravity pull</i>
nor its engine acceleration</span></div>
<div><br>
</div>
<div>I think that the central start should be central star’s.</div>

<p>Yep.</p>
<p>Thanks<br>
