  • RE: Regular polygons example

    There are many ways to do anything. ✌

    The simpleRotate() function isn’t wrong but reminded me of a small piece in the new star primitive (new in V2).

    const getPoints = (vertices, radius, startAngle, center) => {
    var a1 = degToRad(startAngle)
    var a = 2 * Math.PI / vertices
    var points = []
    for (var i = 0; i < vertices; i++) {
    let point = vec2.fromAngleRadians(a * i + a1)
    vec2.scale(point, radius, point)
    vec2.add(point, center, point)
    return points

    I hope this provides some encouragement.

  • RE: V2 cylinders

  • V2 cylinders


    One of the BIG goals of V2 is consistency across the API. However, there's an issue with cylinder(), and before making changes we thought a little discussion should take place.

    The internal API for V1 Cylinder looks like this...

    CSG.cylinder({start: [0, -5, 0], end: [0, 5, 0], radius: 3})

    And on top of this, the SCAD-like API looks like this...

    cylinder({h: 10, r: 3, center: true})

    In order for V2 to be consistent, we would like to move to an API that centers the cylinder by default, and creates a cylinder with the given height and size (radius).

    cylinder({height: 10, size: 3})

    Personally, I have always wondered why start and end points were required, as translating and rotating a shape into place is far easier to understand.

    There is one downside. The ability to create oblique cylinders will only be possible by extruding a circle from start to end points.

    @johnwebbcole has a project which does something simular. hopefully, he will be able to add a few pointers.

  • RE: Multicolor (by faces) model

    @gilboonet Cool innovations!

    Colors are becoming very important with the growing number of multiple head/filament printers. The slicing software requires different colors when deciding on the filament to use.

    It would be nice to add the support for colors (materials?) into the OBJ import/export library. I'll chat with you later when revisiting the OBJ libraries.

  • RE: Maker Faire Tokyo 2019

    WOW! That's really cool. I would enjoy that immensely but I doubt you could ship it to Japan.

    Alternatively, if you make a video of the whole process then I could show that during the faire. 🙂

    If anyone has a nice design then I’d be glad to show at the faire. If small, I may even print an example.

  • RE: google+ data?

    OK. I archived what I could down load using the crappy tools from Google.

    I’m pretty peaved at the results. Obviously, Google thinks that a bunch of monkeys can write software to download web content. SIGH

    Greetings Everyone!
    What video or website do you suggest for a total JSCAD beginner.
    Specifically, 5 middle schoolers were challenged to create ancient Egyptian artifacts using jscad.
    How do you suggest we begin?
    Thank you for any references.

    Gilbert,  Thank you so much.  You were so helpful that I found Tinkercad.  After watching your video I realized that jscad may be the next step for those who want to dive deeper after learning the basics.  Have a great day!

    New JSCAD User Group Forums

    We have tried and tested several solutions, and decided that an easy to use neutral forum would be best. So, the new forums are located here:

    Please say 'Hello' via any of the new forums.

    If you find any issues or shortcomings then please let us know.

    By the way, NodeBB has graciously hosted the new forums for free. And that's a huge plus for the JSCAD project and the JSCAD users.
