During the recent POVCOMP 2004 competition, I created a lot of fairly detailed models that I think other people might find useful for their own ray-tracing work.
By clicking on the above picture, you can download a zip file that
Pencil.inc and the
files. The include
file contains the models and the pov file demonstrates their use.
This model is very similar to the one I used for pencils in my POVCOMP
entry. I wasn't quite satisfied with that one, since I hadn't had
time to work on the textures, so I improved them before releasing this
include file. The model is built using the hexagon shape from
I used a created a "sharpener", an object made up of zy-planes rotated
in the z-axis
and around the x-axis to cut away the material at the tip of the
pencil. In order to get a slightly used looking pencil tip, I
clipped the first three millimeters off the tip of the pencil and stuck
on a small sphere. The text impressed into the pencil by
subtracting a text object from the body of the pencil.
There are several macros in the include file. The only two you
are likely to use are
. There are examples in the
Pencil.pov file that
is included in the zip file.
