formula says "Syntax error: Right hand value of operator ( is Null."
Any insights into why the formula isn't working?
Here is the formula that is plugged into the y-coordinate:
(-1/15)*Sin(u)*(3*Cos(v)-3*(Cos(u))^2*Cos(v)-48*(Cos(u))^4*Cos(v)+48(Cos(u))^6*Cos(v)-60*Sin(u)+5*Cos(u)*Cos(v)*Sin(u)-5*(Cos(u))^3*Cos(v)*Sin(u)-80*(Cos(u))^5*Cos(v)*Sin(u)+80*(Cos(u))^7*Cos(v)*Sin(u))
Here is the link to Wikipedia to see the formula:

inal surface, creating buckling.

I experimented with many different texture effects. In the end I decided i liked the idea of the outer surface being eroded smooth. With the articulate texture protected within folds.

and diffuse radiation for 365 days at noon (12:30)
As you can see there are some bumps that I have discarded as dependant of geometry (Did simulations with different geometries even with just an horizontal surface to analyse and nothing else.) Also discarded from the solar position since the bumps happen in different days as you may see in the graph. I have also tested it with Diva and honeybee so I guess it has to be with RADIANCE. I got this data reading the illuminance files from an annual daylight simulation.
I guess it has something to be with how RADIANCE transform radiation to luminance (luminance = (RED*.263 + GREEN*.655 + BLUE*.082) * 179) And how it determines the values Red, green and blue of the spectrum for a determined solar radiation. I guess, because I was unable to learn how RADIANCE calculates this spectrum, that it has to be dependant of the radiation and solar position with a quite large difference of spectrum.
Normally this bumps are hiden behing the variation of radiation over the year, and I guess that the tool was not designed to have such unrealistic constant radiation, but I would like to know why this happens.
Can anyone help? Any clue is welcome!
Thank you.

ase to give the same result using a graph mapper with a parabola as in the attached file
Unfortunately it never gave the same result ..... is it a mistake in the book ?!…
15 and >90 then add "red" to the strings/int list.
pseudocode :
create list of strings
load bitmap from file path
get bitmap height
get bitmap width
count pixels -> (width*height) -> create a new int (pixelCount)
check every pixels color :
loop till i = pixelCount-1
if hue < 20 and >80 then add "red" to string list
if hue >20 and <40 then add ... etc.
output string list

(about 80 000), with closest point, area and a point distance components set in "cross reference", so it was very very loud... (10^7 or 8 tree elements, and it takes 15minutes).
As you say in your second paragraph, it could be possible to divide this amount of points into multi-threaded lists, without touching the sdk, one component at the time. Is it something everybody can script in a VB component? Because if it is, I start scripting immediately...…

However, this is not your problem. The file you have uploaded abruptly stops. This is usually a case of saving the file to an external drive and disconnecting it before file save has completed. If you don't have another copy then you will not be able to recover this.…
ies for the inconvenience.
If possible, we would like to show DIVA during our workshop in Sao Paulo. Is Radiance installed during the setup process and is it going through Ecotect?
Many thanks and all the best,
Arthur…
