that is definitely question for regl folks

This is a cross post from https://github.com/jscad/OpenJSCAD.org/discussions/875
this demo also aims to be a template for future jscad tutorials

Here is a presentation of a proposal for a new jscad feature: http://3d.hrg.hr/jscad/three/new_params_proposal/parameters.html#0

It is an additional syntax that can be used instead getParameterDefinitions to simplify writing scripts that use parameters.

The intention is to keep getParameterDefinitions and have also this alternative way of defining parameters

the idea is allow developer to write the source source file like this:

function main({//jscadparams
  // size
  radius = 22,// Radius {type:'slider', live:1}
  // location (initially closed) {initial: 'closed'}
  x=0, // {type:'slider', live:1}
  y=0, // {type:'slider', live:1}
  z=0, // {type:'slider', live:1}
}){
  return translate([x,y,z],sphere({radius, height:x}))
}

and the script does not have to provide getParameterDefinitions

The parser would internally generate this definition based on the source above

function getParameterDefinitions(){
  return [
    {"name":"_group_1","type":"group","caption":"size"},
    {"caption":"Radius","type":"slider","name":"radius","initial":22,"live":1,"min":0,"max":44},
    {"name":"_group_2","type":"group","caption":"location (initially closed)","initial":"closed"},
    {"caption":"x","type":"slider","name":"x","initial":0,"live":1,"min":0,"max":100},
    {"caption":"y","type":"slider","name":"y","initial":0,"live":1,"min":0,"max":100},
    {"caption":"z","type":"slider","name":"z","initial":0,"live":1,"min":0,"max":100},
  ]
}

and the form would be something like this:

also, this demo uses a new worker implementation (with regl-renderer) that renders to offscreen canvas transferControlToOffscreen so both renderer and script execution are in the worker.

I am rather new here and I am trying to contribute a bit, but all in some spare fun time for myself.

I am curious to know what you are trying to accomplish, but unfortunately have no time to freelance.

So if no devs are available, I could help a bit.

@z3dev does your sabatical mean: no more releases until sept 1st ?

it shoud be no problem, as you can generate 2d as well as 3d shapes.

You could have different colors, but I think right now, you have no option for line type.

If you start with a simple file design.js, save it in a folder and use editor of your choice.

open https://openjscad.xyz/ and make sure you check the option "Enable Auto-reload"
drag and drop the file into the window and you will see the model

change your js file and save, changes will be picked-up automatically.
openjscad checks for changes every second, but if you want to see changes even faster you can use livereload.

one way to use livereload is via nodejs
if you have nodejs just run
npm -g install livereload
go to the folder with your design and run:
livereload

you must do the livereload step before you drag and drop design into openjscad window.

@RunningUtes

there is one discord server with many cad channels, there are just few ppl on jscad channel . Spread the word, add tickets to github, it is nice to have new community members.

@z3dev did a really nice job, I am stealing his thunder a bit by letting you see the preview of the project function

it is in the master branch if you have openjscad dev enviroment you could test it right away.
I am sure it will be available soon on the https://openjscad.xyz/ website

again , thnx @z3dev , this looks veery nice

I think you need to wait just a bit more.
https://github.com/jscad/OpenJSCAD.org/pull/843

based on the comment for that pull request, the project function is comming soon

@gilboonet if not localStorage, postMessage could work ... as design is running in worker.

and I will look into how to integrate more closely so we can communicate with the embeded jscad script.

PDF button fires a node js script that read that file and create a pdf from it, as I didn't find a way to fire that button with V2 I didn't add it.

can u share that script ?

Hi ,

I have taken your script and added some performance improvements to enable cool user interaction with the slicer

http://3d.hrg.hr/jscad/three/threejscad.html?uri=examples/sqed/index.js

by default "model preview" is ON and you can see the slices in 3D superimposed over the selected obj model.

speed improvements mean you can move sliders and have live preview.

if you uncheck the "model preview" you will get the 2d view of the parts with all the cuts for interconnecting like in the original version.

I will look into making a a new type of param that is file upload/url so that way users can use your script with their model just by accessing the website and no needing to know how to tweak the script.

this version ov jscad viewer has only stl export (I was lazy and it is only one I use) ... how did you generate PDF ?

@gilboonet this one?
https://cricut.com/en_us/essentials/machine-tools/blades/knife-blade-drive-housing.html

that is actually a cool machine. I use a 3d printer alone, but I think my wife would use this machine too.
Do you have some recommendtations, I feel like buying it:
https://cricut.com/en_us/machines/cricut-maker/cricut-makerr-essentials-bundle-champagne.html#product_detail

are there some other useful things there to buy aside from the machine ?

... I mean are there some must haves that would be good to take right away ?

which cutter ?

There’s a new projection function in the works. Hopefully, it will be available in one or two weeks.

there is need for projection and slice ...

although one could make a thin slice with subtract and then use projection to make a 2d shape out of it.

For now, maybe a new page in the user guide would help.

ok, I am ok with that, but for what part exactly ?

That is a very interesting use-case.

One thing that comes to mind is that for example if you can have an additional type of parameter (file) we could make a script that returns empty array in the begining and then when file is uploaded into that paremeter (local file, or external url) the you can play with other options.

It would be a type of script that would work directy on the openjscad.xyz ... and of-course in that case emdbeded in your website for example.

I will look into it and see if I can incorporate support for the use-case in the new jscad website.

One of the things other users have asked for is to have a showcase page/website to link to interesting projects using jscad and of course if those projects link back that helps too.

This would help to build an active community and give incentive for others to join.

I am sure @z3dev would like this too.

I would not go overboard with big ideas, but instead small steps in that direction (like that url proposal for integration and sharing). I would like to connect with you as you are active here (from what I can see) .

@gilboonet I have sent you my email in the chat section of this forum, so we can get in touch as I would like to work closely with you regarding the jscad integrations.

Hi,

I am actually in process of taking apart jscad web V2. The devs that made it are gone and the framework used is confusing for me.

I have an alternative engine that I know how to setup with already few nice improvements that I woul like to bring back to openjscad.xyz

http://3d.hrg.hr/jscad/three/threejscad.html?uri=examples/parametric_butt_hinge_3.7.js

drag and drop of files like openjscad does not work, but you can run scripts with uri=parameter.

I have seen few cool projects of yours that use openjscad in the forums here, and I am interested in helping you bringing them to V2. you have a pretty interesting set of use-cases and it would be great to support them.

I have also created a discussion page to improve embedability of jscad:
https://github.com/jscad/OpenJSCAD.org/discussions/837
that mentions tight integration via postMessage but there are few security concerns.
