- 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).
