You may download our most recent Excel spreadsheet from http://www.marvl.com/downloads/Raeli_Science_Study.xls. We can reliably predict the RGB colors expressed for a given HSL vector, but we have not been able to determine the mapping relationship between Location and Colors.
The Raeli_Science Guild has been torn down. Please see Raeli Ovens if you are interested in our current Raeli related activities.
We obtained the exact color information that we wanted, for approximately two dozen ovens.
We rebuilt ovens in identical locations, offset by 4 coordinates NSEW, at various times and with various avatars, and the HSL vector remained the same. Likewise, we could not detect any correlation with elevation.
We were not able to find a mapping transform between location and the HSL vector. The map appears to be a complex sinusoid, akin to the carrot waves, but we can't generate enough periodic data for a Fast Fourier analysis.
Raeli Oven Profiles
We already have a ton of Raeli Oven information that is based on color sequences and RGB measurements, such as the Color Map, but Teppy did a nice job of concealing the Location:HSL:RGB transform for the Raeli Ovens. Right now we have more bad fits than good theories, but we're still working on it, hence the current effort.
The Raeli Science guild exists for the sole purpose of sharing Raeli Ovens while they are being evaluated.
All members will be elders who will first transfer Raeli Ovens to the guild, and then recover them.
Our objective is to correlate the location of any Raeli Oven and the associated HSL vector, and thereby predict where to look for an available clay patch if you need a particular color sequence. Once we understand the Location:HSL:RGB transform, we'll modify the values currently shown as replicate X and Y.
Methods
Join the Raeli_Science guild, just north of the Seven Lakes Chariot Stop at 1443 1830. You must own several Raeli Ovens, you must be a guild Elder if the ovens are guild owned, and you must be willing to transfer your ownership to Raeli_Science for a few days so that we can chart your ovens.
Transfer the Ownership of your Oven to Raeli_Science and contact Seshat or MarvL. The status will be listed as Shared. You'll be an elder in Raeli_Science, so you'll be able to use your ovens and you'll be able to recover your ovens at any time.
MarvL or Seshat will chart your oven, taking a snapshot of the oven color and /clockloc every game minute. We're using Hypersnap to automatically take a snapshot every 20 seconds, 400 snapshots per Raeli Oven. The full set of snapshots are available if you need them for analysis. The status will be listed as Charted. The owner should recover the oven at this point.
We'll pick off the first snapshot after each color change, with it's timestamp, and post the snapshots at Raeli Ovens and the subsequent pages. The status will be listed as Posted.
We'll also be picking off the RGB colors of a color change snapshot that's near the midpoint, on raw snapshots we're looking at the thumbnails and looking for RGB 260 <= Min+Max <= 261 and then scanning a row near the bottom of the snapshot looking for jitter, and using the jitter corrected values in our Excel Model to determine the associated HSL (Hue, Saturation, Luminance) vector.
As the displayed RGB colors are an approximation of the actual HSL colors, and as there's a bit of artifacting and some roundoff error in the display, the sampled RGB values and consequently the HSL values are only +/- 0.5%. The model for the indicated HSL value occasionally misses an observed tile color; we know that.
We'll provide a link to the HSL model as soon as we get it tighted up. The calculated Hue and Saturation values will be posted both on this page and on the snapshot page. Once we're happy with the Location:HSL:RGB transforms, we'll go back and determine a more reliable means of sampling the RGB values, if need be. Hopefully an accurate Location:HSL:RGB transform will allow us to entirely ignore the RGB values.
Theory
Our working theory is as follows:
Hue and Saturation are static for a given oven, regardless of time of day or avatar position. The Luminance is recalculated approximately every 30 realtime seconds and ranges from White to Black in about 140 realtime minutes.
There are small variations in the minutes per color, and the minutes per color is erratic. The time per color is not locked to either realtime nor to the game time. There's a run to run variance of about 10%. Take a look at the test runs for the Sunset Enterprises oven in Caldera Park. Fleeting colors can be hit or miss.
There are never more than 8 unique values in a color swatch. Basically, inbetween HSL values will jitter between adjacent R, G, and B values, and 2^3 = 8. Occsionally one of the values will jitter by two rather than one.
Hue is a function of Cosine(Y), although there is enough varience to suggest that there is some other factor as well, perhaps the elevation of the oven.
Saturation may be a short period function of X, but we don't have enough data yet for a useful approximation.
A low saturation oven shows up as Gray, regardless of its Hue
The displayed RGB colors, and therefore the HSL vector, is far more sensitive to changes than is the indicated tile color, which snaps to the nearest of 142 predetermined RGB values.
Clay Patches repeat about every 100 coordinates along the river, but they have been found as high as 30 feet above the water, and in areas with no water in sight.
Raeli Ovens must be separated by 50 coordinates, but you can fudge this as much as 4 coordinates by standing on the far side of the oven
The edges of the map wrap around, which is an inherent characteristic of a periodic function.
We're currently examining the elevation of previously tested ovens, and we most certainly need to collect rigorous data for more ovens.
