I have been getting requests for more targets than i have coded so far.
Most are requesting the horizontal matrix.
I will build a target generator for that, but i wanted to let all of you know that you can make your own target files.
horizontal matrix, LEDs wrapped around your bush, leds on the side of your house, stack matrix quads on top of each other. You can do it.
Here is the basic concept for Nutcracker targets. Whatever you have has to be divided into vertical strands. Each strand has pixels. Those pixels will always start with Pixel #1 at the top. For each pixel include the x,y,z location in world coordinates.
Well, thats it.
Here is what a target file looks like. It should be a space delimited ASCII file. Comments begin with a hash mark. Blank lines are ignored.

So let me show you how to make one in pseudo code:
A user here has 12 flat strings, 30 pixels each. He wants to string them horizontally and make a horizontal matrix.
He probably wants scrolling text to work and create a nice sign board.
We need the above file to be created.
# In x,y,z world coordinates, we can consider this a 2D object. In Nutcracker space the z axis is up and down, the x axis is left and right, the y axis is front and back
# we will start at the bottom of his first string and consider that (0,0,0).
# Y axis will always be 0 since this is a 2d object. Let us assume 3" spacing between his pixels and 3" spacing between the rows of strings. My aha moment was
# when i realized these dimensions do NOT have to match your display, they only have to be keep referential intact for my calculations. Let me simply this
# by saying always use 3" or 8cm for the spacing between your objects and all my effects will work.
for (s=1;s<=12;s++) # Lets go through all of his strings
for (p=1;p<=30;p++) # and for each of his strings look at all of his pixels.
{
y=0.0; # we have a 2d shape, the matrix will be a flat plane
x=p*3; # in a horizontal matrix, pixels are going horizontally
z=s*3; # and strings stack on top of each other.
strand =p; # i need the verticals to be strands. 30 pixels laid out horizontally. We will therefore have 30 strands
pixel = 13-s; The very top string needs to be labeled as pixel #1, the very last (bottom string) needs to be labels as pixel 12
print "HMATRIX ",strand,pixel,x,y,z,s,p;
}
The code in red will produce a target file for a horizontal matrix.,
This will work with all effects in the Nutcracker.
As you can see , making the target files is pretty simple. It gets a little more complex if the object is in 3d.
Make a target file and email it to me, i will add it into your library of targets. I will make a screen where you can upload your own targets. The only other little cleanup is each target has to be entered into the mysql database.
Most are requesting the horizontal matrix.
I will build a target generator for that, but i wanted to let all of you know that you can make your own target files.
