I came across this equation that simulates the color on a butterfly wing.

So , you now have a new effect.
The RADIAN_SHIFT parameter is how much each frame the colors are shifted. I found values between .05 and .1 are good. The higher the number the faster the shift across the tree.

If you increase the radian shift, you get faster color movement

And if your show has heavy metal, try a radian shift of 1.0

Sean - - I don't think you truly realize what your tool means to everyone even "sort of" thinking of getting pixels - you've not only made it mind numbingly simple but also free. Even a basic Madrix license costs $500 and one to get to a good number of pixels is closer to $1500. I knew Madrix was out so I for one was resigned to generating simple chases, etc with my new tree - but now that has completely changed.


I'm sure quite a few of us would be more (and I mean MORE) than happy to kick in a few bucks to support you - better/faster web hosts, better PC, etc

Thanks for the support. I will put a pay pal donate if anyone wants to kick in a few bucks to offset some of my costs. It is NOT needed and the tool will stay free.


I have released a new verdsion of the butterfly effect.


Now you can define the color range that the butterfly wing will have.


Set START and END color to #FFFFFF and you will get the entire color spectrum.


Here are some examples of using a smaller color band.

Be aware that my animated gif's only use 256 colors. This causes banding on the animations, that should not be true on our actual trees.


thanks

Sean,


Have you made a model whereby we can construct an element with curves?


Charles

Not yet, i have maybe 30-50 new effects in my plan. curves is certainly one of them.


avi movies
fireworks using physics for the particles
snow in a snowstorm, particle movements
lots of f(x,y) functions. Look to the demo gallery on http://gnuplot.info for some ideas


.etc

short answer is yes. But i need to bring the radian back to the same value we started with. I need to calculate total radian shift and get it to come back to original value after maxFrams.
I dont like the jump either. Just more stuyff on my to do list.

Ok,


Enhancement.


I now readjust your radian shift parameter so that it is a multiple of 2pi


You pass in a variable called $radian_shift. This is what causes the movement betweem frames. The issue is it was not an even multiple of 2pi over the frames.


This corrects your entry.


$new_radian_shift = intval(($maxFrame*$radian_shift+0.5)/$pi2)*$pi2/$maxFrame;


some examples


radian_shift new_radian_shift
.01 .0785
.05 .0785
.1 .2355
1.0 .942
3 2.983
7 6.9865


You just pick values, ill make them into a multiple of 2pi and the max frames.


try Butterfly now, there should be no jumps.


thanks
 
Sean,


I am trying to relate the one you listed to some type of Christmas element. That looks more like a grid in Blender that is used to warp video than it does a matrix grid.


I will stay tuned. Either next month or May, I am buying enough pixel ribbons and controllers to demo each one of these designs with LOR S3. Should be fun.

New feature.


Butterfly now has 3 equations u can use


1)
NumberedEquation1.gif





2) sin(x*x + y*y) / (x*x + y*y)
hidden.3.png



3) sin(x) * cos(y)
hidden.4.png



New option , butterfly fomula. Values 1,2 or 3


So , leaving all other parameters alone, here is formula 1 (our original butterfly wing).
