(The plot might take a few seconds to render; be patient.) We want
to modify this plot so that a perspective projection is used, and with a
viewpoint as if we were standing near the edge of the vineyard:
set(gca,'proj','per')
axis equal
set(gca,'cameraposition',[.5 -1 .2])
axis vis3d off
set(gca,'cameraposition',[.5 -.1 0.03])
Exercise 18 (Page 132)
You should not use
title
instead of
text
because the title disappears
when you do
axis off
.
Exercise 19 (Page 145)
The following code does the job. Items are “grayed out” by setting their
“enable” property to “off”.
uimenu('Label','File')
uimenu('Label','View');
E = uimenu('Label','Edit')
uimenu('Label','Options')
uimenu(E,'Label','Cut','Enable','off')
uimenu(E,'Label','Copy','Enable','off')
uimenu(E,'Label','Paste')
uimenu(E,'Label','Rotate','Separator','on')
S = uimenu(E,'Label','Scale')
uimenu(S,'Label','10%',...
'Enable','off')
uimenu(S,'Label','50%',...
'Enable','off')
uimenu(S,'Label','150%',...
'Enable','off')
uimenu(S,'Label','200%',...
'Enable','off')
uimenu(S,'Label',...
'Custom Scaling...')
Exercise 21 (Page 164)
A truncated pyramid can be produced using the following code:
