Flash on Clash™ Mixing Techniques
During the development of CFv6 and our Flexiblend color mixing engine, the Flash on
Clash effect was modified to fit specific color mixing requirements, so that the Flash
on Clash color (defined by fled1, 2 and 3). However, customers liked a lot the FoC
effect developed for CFV5 and further referred as “on-top” FoC as it is defined by
adding a secondary color or die (dice) on top of the blade main color. So, technically,
from the Flexiblend color mixing engine point of view, it is not a color change but
rather the addition of another light source (which defines pretty well what the Flash
on Clash is).
So due to popular demand, I designed a Flash on Clash engine that is compatible with
both FoC styles by selecting, for each led die, which one will be color mixed during the
Flash on Clash, and which one(s) will be added “on top”.
The FoC configuration uses a new parameter
focmix
in the configuration file. The
parameter is defined as a bit field, in a similar way than the accent LED sequence
states. The left most digit (0 or 1) is color channel #3 (or formerly FoC2) while the
rightmost digit is color channel #1 (onboard driver).
A zero indicates the concerned die isn’t mixed (therefore “on-top”) while a one means
that the die will be color mixed.
As an an example, the default focmix value is:
focmix=011
which means that color channels #1 and #2 will be color mixed while color channel
#3 will be added on top.
The di(c)e added on top have their own timeline and behavior using the parameters
focd
(duration),
focp
(period),
focr
(randomness) and
foc%
(strength) while the
mixed di(c)e will be handled by the color mixing engine and shimmer parameters &
timeline.
That very flexible FoC mixing system allows a lot of scenarios to be achieved. Here are
a few examples.
A)
Using a GGW tri-rebel or tri-cree. Both green dice are wired in parallel. The
main blade color isn’t affected per say during Flash on Clash, the white die is
added on top of the 2 green ones during the FoC effect.
The green dice are configured for a drive of 900 channel #1, white dice is on
color channel #2, leading to the following configuration:
color= 900,0,0
fcolor = 900,900,0
focmix=001
B)
Using a RGB tri-rebel or tri-cree. The 3 dice are mixed. One color is defined as
the main blade color, while the FoC has another color. That configuration will
use FoC mixing on all dice. Let’s say the led is wired as RGB. Main blade color is
purple (red + blue) and FoC color is whitish. FoC parameters aren’t used, only
