IMAGE DESCRIPTION:
This image is a brief look at how man has lit his world through the ages, from
the candle through the light bulb to the laser. Also in the image are some of
the discoveries about light - the background interference pattern and the three
freestanding images of interference patterns, the dispersion of light by a
prism, Maxwell's electromagnetic equations and a circuit for the demonstration
of the photoelectric effect (the latter are on the piece of paper and show the
wave-particle duality of light, hence the "YET" next to the circuit diagram).
The wave-particle duality is also shown by the wave and photons running through
the image.
The dark line inside the bulb is an artifact of the refraction in the material
applied to the outer piece of glass I think the only way to get rid of it would
be to increase the ray depth, but my machine isn't fast enough for me to do
this, unless I don't mind waiting many more hours for the render to complete.
DESCRITPTION OF IMAGE CREATION :
The candle, candlestick and most of the light bulb (which consists of many
separate objects. It is actually a complete model of a bulb, though not all
the detail is visible in this image) were created using the same technique -
create atube and make a reference clone of it. A MESHSMOOTH modifier is
applied to the clone and an EDIT MESH to the original. The mesh of the
original is then manipulated to get the basic shape, with the MESHSMOOTH giving
the clone the final smooth shape. An in-depth tutorial of this technique
(which we call the milkshake glass technique. See the tutorial and you'll know
why) is available thanks to Ashton Mason at
http://www.cs.uct.ac.za/~amason/silicon.trip/Tutorial.
The candle flame consists of 3 combustion effects of different size and colour
and inside the flame is the only light in the scene. The top part of the
candle is lit with two target spots to give the impression of the light passing
through the wax.
The wave and photons have a TAPER modifier applied to them to give a greater
impression of depth.
The "interference" patterns were all created in Photoshop wit Kai's Power Tools
3 GRADIENT DESIGNER. The 3 free standing ones started out as 3 separate
red-to-black, blue-to-black and green-to-black gradients which were then pasted
together using different glues (so they're actually just variations of the same
image).
