I was impressed by this picture but it did look like a bit of a stubby
pencil to me.

This data file makes a pencil along Y axis with the label "DKBtrace 2.11"

Translation to English and DKB version 2.10 by Aaron A. Collins with
a bit
of help from David on the imagemap registration.
NOTE - unless this is rendered at a minimum of 640 x whatever, the
DKB logo
is quite unreadable.
The Pencil - major export of Faber, Pennsylvania, due to the plentiful
presence of pencilwood trees and eraser-root plants, and the nearby
graphite mines.

{ Now for the complicated image mapping:
Currently, the pencil is standing up in the Z axis:
Z
eraser ^ *VP

| |----/ Y
| /
| /
| /
| /
| /
point |/
-------------->

We want the image to be mapped as follows (viewed from the +ve Y axis):
Right
---- z=28.0

Top |ar| Bottom

---- z=12.7

x=1.75 x=-1.75
The image map above gives (viewed from the Y axis):
^ Z
1,1 Right|
------|
| |
| |
Top | |Bottom
| |
| |
<----------
X Left
Which is at least in the right orientation.
Now, we must scale the image so the letters are the right size. }
SCALE <15 1 15> { Never use 0 for any scale value }
{ Now, we align the top left of the picture to the proper point on the
pencil. This is a bit tricky because the top left of the picture is now
at x=15 z=0. We have to move it to about x=-12, z=12 because the letters
don't start at the very top of the image. }

{ As you may have guessed, this still took a lot of trial and error to
get it
right, but some analysis of the picture before hand saved a lot of
time. }

you know, even at this early stage, the SDL is already better than most SDLs in
most other renderers, most notably Renderman! I understand they use it just to
exchange mesh data with external tools, but damn! Even better than all this XML
madness of late...

Strange, at the time I never thought of it as an early stage :-).
