A souvenir waterbottle for the Low-Key Hillclimbs.

Cylindrical AXFET :
This is a simple rendition of a cylindrical-gate AXFET. A metal S/D is connected to the Si channel with a thin (rendered green)
passivation layer. The focus device is cut-away. This is part of my return to POV after a long absence.

Inspired by the
2007 Low-Key Hillclimbs,
dice and coins rest atop a crystalline pillar which extends into the sky.
The pillar: the mountain, the dice: the luck of cycling, the coins: its value.
My first worthwhile POV project after a long absence.

Capture the Night II :
This is variation on my first project in POV-Ray,
which was a close rework of a similar
scene rendered in Ray Dream Studio. This one uses the spark
generator credited in the Alto Velo image. The moon is captured
by Clarkian monoliths on some unknown location while the Earth
shines unmolested in the nighttime sky. The cage superstructure
is the latest addition to this image (rerender 11 Apr 1998
with adaptive supersampling -- 20 hours!!!).
less-compressed version was submitted to the
Internet Ray Tracing Competition
for the April
1998 (Night) round. It scored 12.52 points (20 maximum) to
place 29th out of 131 images.
Voter comments are available from the contest web site.
Alto Velo :
POV Project #2, and the first to use text:
This is a variation on the
Alto Velo Cycling Club
logo. The mountain was generated using
a height field done with Bryce 3D. The lightning was done with
the spark generator available at
Pile POV-Ray Archive. The rest is pure POV-Ray... nothing
The ball is mapped to a sphere from a GIF from the Worth web site... other objects
are all pure POV (29 Jun 98). A
was entered in the
June 1998 (Nature) round
Internet Ray Tracing Competition,
hammered by the voters, placing 85th out of 112 entries. Clearly my
assetion that baseball was the "natural" sport didn't fly... :)
ordered GeSi deposited via diborane-doped chemical vapor deposition
from germane and silane sources in lamp-heated quartz reactor.
Modeling : POV using a blob, halo, fog, and some CSG. This is version
6 of this image.... it had to be rendered in two parts because the
whole lattice couldn't be stored in 128 MB memory at once. Nevertheless,
it took 4 CPU days to render. (16 Aug 98)
A less compressed version
of this image was submitted to the
30 Aug 1998 (Elements) Internet Ray
where it placed 34/109 (full tabulated
source code (zip),
A closeup view of the rear portion of the drivetrain, modeled in all CSG. Note there is a flaw in the
derailler due to the simple modeling used there -- te partition in the ellipsoids is quite clear.
This is the second revision rendered since I finished the bike model... it was rerendered
using radiosity, which really added richness to the shadows, and in a vertical aspect (08 Aug 1998).
A 27 frame GIF to test my chain routing algorithm (16 Jun 98).
Work on this has been delayed by other projects (see above), but I am
finally finished. Cables and housings are in place,
with the valuable help of Ron Parker's "torpatch.inc" 3.1 macro.
This version is a rerendering with different lighting, radiosity on,
and a different camera position (20 Aug 98).
This is another view of the bike.... the lighting on this rendering
could perhaps use some work. This version was done with
radiosity, my first attempt at this. This rendering corrects a minor
error in the rear brake cable routing (17 Aug 98).
Bike Shop :
This is a very early version of my bike shop. Clearly there is still
a lot to do -- it's way too empty. For example -- no bikes! The
wrench is from
Bill Fleming's work.
The phone and clock are from
the POV Object Collection.
The poster is a seriously hacked photo. The rest is CSG with some help
from sPatch for the crank arm and rags. More to follow...
Version 6 -- texture adjustments, yellow pages added : 01 Dec 1998
Truing Stand :
This is detail from the current version (as of posting date) of my bike shop
scene. All objects are hand-coded by me except for the phone, which is
modified slightly by the phone object at The
Twysted.net POV Objects Collection. It remains a work in progress.
(version 3 -- see bikeshop.jpg : 04 Dec 1998)
This is the result of an experiment I did for the last IRTC round.
Rendering time was 31 hours due to the high sampling rate used in the
media (1000 media intervals). This remains a work in progress, and in that spirit
the source code is also available. This is
the second version posted here.
