[TheForge] basket candlestick models uploaded to photo page.

[Terry L. Ridder]

hello;

i have uploaded 4 povray renderings of the basket candlestick
project on page 45 of blacksmith cookbook, recipes in iron by
francis whittaker.

just plain straight 1/4" round rod.

the 1/4" round rods have been expanded out.

the function used to expand out the baskets was a
damped simple harmonic motion--underdamping function.
the function and parameters are given below.

exp((-beta / 2) * t) * (A * cos(gamma * t) + B * sin(gamma * t))

where t is equal to the twist_count. twist_count range was 0 to 300.
A       = 0.0;
B       = 3.0;
beta    = 0.3;
w0      = 0.4;
alpha0  = pow(beta, 2) - 4 * pow(w0, 2);
gamma   = sqrt(-alpha0) / 2;

the 1/4" round rods have been twisted in a simple sine wave.
the angle range was 0 to 1-2/5 pi.

the completed candlesticks.
combine the damped simple harmonic motion--underdamping function
and the sine wave function the completed basket candlestick
project is obtained.

now i do have a couple ideas now about how to make each rod.
