The LSX tutorials thread!

Spirals are easy. There are two ways:

-Create a static dot with a high number of points (see very first tutorial here on how to do that)
-Place on timeline, use PreMoveX, PreMoveY, PreMoveZ
-Expressions:
PreMoveX: sin(idx*10*pi)*0.5+0.5
PreMoveY: cos(idx*20*pi)*0.5+0.5
PreMoveZ: idx

But it's also possible in the external PicEdit program (basic and pro only):
-Open PicEdit
-Edit >> Script
-It's easiest if you just open a new script: File >> Open, there are a number of example scripts in Global LSX Files/PicEdit Scripts, the Sinus3D one should work good as a basic example
-Change the code (basically just swap the X and Z coordinates around):

Elegant as always, CMB! You should consider adding to your equation book a series of equations/routines to take that same group of points and turn them in to a variety of basic shapes: circle, square, tetrahedron, goat, etc.

that would be awesome! even releasing a bunch of SFX modules for these functions would surely improve swami shows.

i had no idea you could do scripts in picedit..

But... that's just very basic! :P
Yeah I only found the script thing in PicEdit by sheer luck, it's not really documented anywhere. Does anybody recognise the language? The syntax isn't 100 % clear for me. Editing existing scripts is no problem but maybe it's nice to see how far you can push this... But I like expressions on the timeline more since then you can use real time parameters.

maybe to you, but i'm just a runt sasquatch shaved down and taught to talk.

It appears this is visual basic syntax. I was able to program an "if then else" statement as well as use the "modulus" function to make some segmented circles. This is so much easier than drawing color into the picture. I have also been able to blank segments of a circle using the same idea as below just using the blank command rather than color command. There is alot of potential here for quickly allocating part numbers or color to certain segments or points of a pattern. I am also wondering if you can load an existing Pic file and change the part number or color then re-save the file under a new name. This will be tested soon.

Anyway here is a script file have been playing with the last few hours. Enjoy.


Start Code:
n = 100

Pic.N = n

for i = 1 to n

segment = i/10
blank = segment mod 2
if blank = 1 then
Pic.R i,0
Pic.G i,0
Pic.B i,255
else
Pic.R i,255
Pic.G i,128
Pic.B i,0
end if


x = sin(i/n*2*3.1415)*0.49+0.5
y = cos(i/n*2*3.1415)*0.49+0.5
Pic.X i,x
Pic.Y i,y

next

SET objShell = CREATEOBJECT("WScript.Shell")

Pic.SaveToFile(objShell.SpecialFolders("MyDocument s") & "\My LSX Files\circle_001.pic")

End Code:

Thanks for sharing, but how to close the cirkle?

You can use the [ CODE] and [/ CODE] tags on the forum, it avoids the forum automatically splitting long text (there is a space in "MyDocument s" in your code)...

I think this would work:

x = sin(i/(n-1)*2*3.1415)*0.49+0.5
y = cos(i/(n-1)*2*3.1415)*0.49+0.5

I was wondering how to do that. Thanks

Thanks a lot CMB, works. First point have to be set blank manually to avoid repeat.
