@z3dev I could easily adapt to any solution allowing to feed a list parameter with files, it will be far a better UI practice than my current one that requires the user to type the file name. Or maybe the ability for a text parameter to receive a file from a drag-drop operation.

I have a script that makes a volume from two svg files that are chosen from text parameters. Then a require is made from those parameters. Won't it be possible to have a list parameter that can be feeded from file names (naturally from project folder) filtered by a mask (like *.svg or profil??.svg ) ?

@z3dev the svg is here : https://github.com/gilboonet/gilboonet.github.io/blob/master/demos/demi_l.svg
What I'm trying to do is a composite volume made of half a revolution of extrudeRotate then extrudeLinear with the same shape. I was able to have both extrusion method return a volume, but they don't coincide.

colorize function accepts an array as parameter containing RGBA values, each from 0 to 1, A is for alpha transparency.
taken from the source :
/**

• Assign the given color to the given objects.
• Note: The color should only be assigned after performing all operations.
• @param {Array} color - RGBA color values, where each value is between 0 and 1.0
• let redSphere = colorize([1,0,0], sphere()) // red
• let greenCircle = colorize([0,1,0,0.8], circle()) // green transparent

@z3dev Do you know why extrudeRotate at 180° doesn't produce the same polygon as extrudeLinear (from the same polygon input) ? Or if there's a way to extrude a (flat) 3d polygon ?

I tried to dig further this design and decided to only keep half revolution of the extrudeRotate and add an extrudeLinear to its flat end. Seems that extrudeRotate and extrudeLinear with the same input result in volumes of different scales. And mirrorX on this input gives a polygon that must be reversed to be correct. At first I tried to use the polygons from the extrudeRotate to do the extrudeLinear, but seems that it doesn't work with 3d polygons, I will try to 2d it as I have a function for that. Unfortunately, I don't see how to find the correct scale to align rotate and linear parts of this design.

This is very nice to be able to do such design even if for the moment it is not complete.

I tried to make a curved volume using extrudeRotate with a bezier curve (svg file) as input, but it didn't work (third meshlab window). So I replace the bezier by lots of lines, but it made the same (first meshlab window). By reversing points order when making the polygon (shape.points.reverse()), it was ok, but this operation result in an error with the bezier svg points. With bezier polygons, there is maybe a smarter way to reverse points ? maybe only reverse physical points and keep bezier control points order, but how ?

I converted some of V1 examples to V2 and when I run them both in V1 and V2, their performance looks the same. I'm on Ubuntu with Firefox both on a very old tabletop pc (with a 2011 Radeon) and on a recent laptop (with Ryzen 3).

@z3dev An option to show/hide slider value would be great. Long ago I made some tweaks to parameters that looked like that, but now jscad architecture is too complex for me to make such changes. On the bottom of the screenshot you can see file browser to import/export parameters that I also added and was of great help to make complex models.

@zorglups The syntax is not ?url=[your_url] but #[your_url]. But on this case, the url is a download url, the script must be downloaded then dropped to OpenJSCAD.org file drop zone (bottom left frame).

Here is its version with parameters, using sliders make an interface easy to understand, but as there is no way to save parameters values nor view slider values, it's not as practical as an interface where you type numeric values. Anyway, it's fine to be able to do that so easily.
It can be seen here : https://jscad.xyz/#https://raw.githubusercontent.com/gilboonet/gilboonet.github.io/master/scripts/PiedGen1.js and the code : https://github.com/gilboonet/gilboonet.github.io/blob/master/scripts/PiedGen1.js

Thanks to V2 examples, I was able to make a script to create a curved and sheated furniture foot generator. I only need to make it parametrable and it will be done.

That's great to be able to use the WEB UI, especially with loading of remote URL ! (Seems that the link to www.jscad.xyz points to this discussion)

@BarbourSmith I saw your post but didn't reply as I wasn't sure it was about. I already tried on V2 the function that splits a solid into pieces as it is something that i use a lot : https://jscad.xyz/#https://raw.githubusercontent.com/gilboonet/gilboonet.github.io/master/demos/gig2i.js The function is scission3d() and the source is here : https://github.com/gilboonet/gilboonet.github.io/blob/master/demos/gig2i.js

Hello, today I needed to make a surface of revolution model, usually I first draw a profil (with Openscad Polygon Editor) then uses jscad.

I did it with V1 (magenta) and V2 (orange). The V2 model is neat, where the V1 model has some faces that I usually need to change by hand in order to extract the pattern I need Once again, this is very good job..

Hello, as on my workflow I'm using obj files where I have groups (facets) that I colored, I was wondering if it could be done with jcsad 2. I didn't realize that immediately, but obj require handle groups by creating an array instead of a sole polyhedron, so it was not hard to do. For the moment I read the groups colors by hand, but they are into the companion file .mtl and could be fetched (I suppose it's for each group on 'kd' entry. Anyway that's already very nice.

const jscad = require('@jscad/modeling')
const { colors } = jscad
const { colorize } = colors

//const obj = require('./Gargouille692.obj')
const obj = require('./6ZonesMat.obj')

const main = () => {
  let cols = [
  [0,153,0],
  [0,153,255],
  [153,214,255],
  [163,102,0],
  [163,254,102],
  [254,204,255],
  [255,255,1]
  ].map(x=> x.map(y => y/255))
  
  let r = obj.map((x, index)=> colorize(cols[index], x))
  
  return r
}

module.exports = { main }

I'm trying now csg on a .obj file imported (require) into V2. It works fine with an intersect, but when I try to make lots of intersect, the return statement has errors.

On my example, height is 104 units, I can return a slice every 3 units, but when I try to return a slice every 2 units (and my real process needs smaller slices) it bugs :

elapse for solid generation: 39 design.js
total time for design regeneration 7015 17 design.js
Uncaught (in promise) TypeError: a is undefined (2 times)

@z3dev Indeed, for those examples I didn't use serializer but import data from obj files exported to .jscad format by Wings 3d. When imported on V2 using require (I suppose that's the way to use serializer), it's visually correct. I will try to do some csg to see if it ok. Anyway, here are the files.
https://github.com/gilboonet/gilboonet.github.io/blob/master/demos/objs.zip

@z3dev The same data applied to V2 gives the same results, the visually correct polyhedra are those having faces order reversed.

@sheffieldnick As V2 is on active development, I don't think that new functionality could be add to V1, but I'm only a user not a developer. This project could maybe help you :
https://github.com/danmarshall/jscad-gallery
Or you could also do a fork. Long ago, I added some functionalities to OpenJSCAD v0.5 so the user can select a data file that will load openJSCAD with a .jscad file and populate it with parameters, but it's very old code (from 2016) that's not on github... http://gilboo.carton.free.fr/OJSC5/edit_ner2.html
