Compo Revived webpage

Just to let people know that I’ve now generated a new webpage to (pun alerts!) illustrate and draw attention to the new release of “!Composition” and give an example of just what it can now be employed to do. The new page is at

https://jcgl.orpheusweb.co.uk/CompoRevival/CompoRevived.html

I’ve also updated slightly the original main “Compo Clues” page at

https://jcgl.orpheusweb.co.uk/Compo/clues.html

to serve as a starting point that now includes a link to the above.

I’ll add some more pages as-and-when the ‘round tuits’ supply permits. :-)

Animated versions of the above new example with user-adjustment of variables seems worth considering. :→ …

Thanks for these examples and Compo/clues is a good introduction to the scripting side of !Compo.
Waiting for the animated version.

Animated is intended. :-) Snag being, when! These days I do things at glacial ‘speed’ as I’m old and keep having other things to do. FWIW the original reason I had for looking at near-field patterns of antennas is for receiving antennas. People buy fancy VHF antennas and sometimes put them in a loft. The snag being that objects near the antenna can disrupt their behaviour and act like extra, ‘elements’ that scatter or absorb some of the EM fields. Thus often degrading performance. Diagnosing this is a bit of a ‘black art’. That allows salesmen to over-sell to buyers.

BTW if anyone else wants to have a go an ‘animating’ the antenna patterns you can look at an earlier ‘clue’

https://jcgl.orpheusweb.co.uk/Compo/script/page3/page3.html

which outlines the method. In this case based on repeated redrawing the pattern with an added phase change to the calculated field so it radiates out the peaks and dips from one ‘frame’ to the next over a cycle. :-)

I have already tested the animation of the sky and the planets, quick question can we save the animation, Intergif was seen by the filer…

I never did get around to writing the page on that! I’ll try and do it soon.

I have now found the files and scripts so may put up a zip of them to experiment with. But pro tem this composcript may give the needed clue if the relevant chars come out right…

(EDIT) Booger! Nope, the forum rendering loses control codes, etc. I’ll put up a zip and point to it.

But in essence:

Make the canvas the size and shape of the animated item. Then run a loop to step frame by frame, each time saving a sprite of the canvas with names in numeric sequence. So you can then feed them all to InterGif to animate as a gif.

Compo automatically creates each frame as a saved sprite. InterGif then takes these and makes the animated gif file.

Ok, have a look at this. IIRC it is what I used at the time to let me generate the animated gif for the web page.

http://jcgl.orpheusweb.co.uk/temp/Rotate3.zip

I’ll do a page on this when I can, and give more details/info. But the zipped file should show how the scripting can enable it.

Thanks, in the meantime I found the animation.move4 script and !Compo can also build the animated gif file, with a script for Intergif.
!Compo knows the current directory of the script, it’s simpler to manage the file:

 

 filename:<.composcript$dir>.tempfile
