current time (if the pedal is on and a key is depressed the value is halved, if the pedal is off the value is 0).
The rest of the definition is just to do something with this data. It uses these values to display each note as different floating colors that move with the wind (using Kangaroo). The strength of the wind changes as the music dynamics change.
If there are several devices connected you might have to change the line device.Open(0) to another number.
(to be displayed with a black background)…
Two things:
90 X 5 is wrong. There are 360 degrees in a circle so just use a constant (360), or 90 X 4.
Don't flatten the output of 'Flip' before 'IntCrv'.

The values in bold are then evaluated using the equations in the file perezlum.cal inside the RAYPATH directory in Radiance..
{ All-weather Angular Sky Luminance Distribution . Additional arguments required for calculation of skybright: A1 - diffus normalization A2 - ground brightness A3,A4,A5,A6,A7 - coefficients for the Perez model A8,A9,A10 - sun direction}skybright = wmean((Dz+1.01)^10, intersky, (Dz+1.01)^-10, A2 );wmean(a, x, b, y) = (a*x+b*y)/(a+b);intersky = if( (Dz-0.01), A1 * (1 + A3*Exp(A4/Dz) ) * ( 1 + A5*Exp(A6*gamma) + A7*cos(gamma)*cos(gamma) ), A1 * (1 + A3*Exp(A4/0.01) ) * ( 1 + A5*Exp(A6*gamma) + A7*cos(gamma)*cos(gamma) ) );
This data is then mapped to the "glow" material that represents the celestial hemisphere...You can edit the climate based sky produced by Honeybee and enter your own values. The other option would be to just use gendaylit from DOS Prompt.…
The angles at which isocurves meet are not necessarily 90 degrees. Rectangles always have 90 degree angles. So what needs to happen when your isocurves are skewed?
