Finally had some time to put finger to keyboard and I thought it was
about time I expanded my repertoire and stopped drawing stereograms.

Rather than just stop them altogether, I thought I'd gradually wean
myself off them, so I had a go at drawing isometric projections.

I have tried to keep the projections very clean and simple, aiming
for a CAD-like image.

These drawings are not really finished, but I've spent enough time
on them and I want to move onto to something else now.

First, here's a rectangle, projected isometrically:


                      . '   -  .
                  . '              '   -  .
              . '                             '   -  .
          . '                                            '   -  .
      . '                                                        .'
  . '                                                          .'
  '.                                                         .'
     '.                                                    .'
        '.                                               .'
           '.                                          .'
              '.                                     .'
                 '.                                .'
                    '.                           .'
                       '.                      .'
                          '.                 .'
                             '.            .'
                                '.       .'
                                   '.  .'
                                      '

The biggest problem I had was making the lines continous. I tried
several methods of linking characters together, but I kept getting
'kinked' lines. Rather than draw lines that I didn't like the look
of, I decided to leave the gaps blank and rely on my brain (bad
mistake!) to fill in the gaps and give the impression of a solid
continous line.


Following on from the rectangle, I thought I'd try and draw something
on the 'floor' that I had created. After several false starts, I
decided to draw a house:

                                                        .d88b.
                                                       d888888b
                                                       Y888888P
                     .   -    .                         'Y88P'
               .'   .               ' .  -.
             .           '    . .  '        ' .
           .                   .              .'
          '..                 .          .  ' :
           :   '  .          .      .  '  . : :
           :         '  .   .  .  '       : ' :
           :               ':'    .:          :   -  .
          .:                :  :'  :    . . : :          '   -  .
      . '  :                :  :      :': : '.'                  .'
  . '      '                :     .:  : : . '                  .'
  '.           -            :  :'  '  :.:'                   .'
     '.                     :  :    . '.   ' .             .'
        '.           '      :    . '     ' .    '  .     .'
           '.            -  : . '              .      '.'
              '.            ''                     . .'
                 '.                                .'
                    '.                           .'
                       '.                      .'
                          '.                 .'
                             '.            .'
                                '.       .'
                                   '.  .'
                                      '

There are quite a few gaps in the lines above, but I didn't like the
kinks that appeared when I filled them in. I also tried to restrict
myself to only a few characters to maintain the clean lines, using
lots of different characters gave a very 'messy' appearance.


Finally, I thought I'd better 'render' my drawing and fill in a shadow
cast by the sun:

                                                        .d88b.
                                                       d888888b
                                                       Y888888P
                     .   -    .                         'Y88P'
               .' . .               ' .  -.
             .  .  .  .  '. .   .  '        ' .
           .  .  .  .  .  .  . .              .'
          '..  .  .  .  .  .  .          .  ' :
           :::.'.  .  .  .  ..      .  '  . : :
           :::::::::.'. .   .  .  '       : ' :
           :::::::::::::::.':'    .:          :   -  .
          .::::::::::::::::::  :'  :    . . : :          '   -  .
      . '  ::::::::::::::::::  :      :': : '.'                  .'
  . '     .':::::::::::::::::     .:  : : . '                  .'
  '.   . . . . ':::::::::::::  :'  '  :.:'                   .'
     '. . . . . . '':::::::::  :    . '.   ' .             .'
        '. . . . . . ''::::::    . '     ' .    '  .     .'
           '. . . . . . .'::: . '              .      '.'
              '. . . . . . .''                     . .'
                 '. . . .                          .'
                    '.                           .'
                       '.                      .'
                          '.                 .'
                             '.            .'
                                '.       .'
                                   '.  .'
                                      '

Again, the shadow doesn't look how I'd hoped it would, but my eyes
were going funny and I figured that the drawing had gone as far as
I could take it.

I'll probably do a few more isometric projections, but I need to
set up a library of lines all the way from horizontal to vertical
first!
