  • jupyter-cadquery

    • Project mention: Show HN: Consol3 – A 3D engine in the terminal that executes on the CPU | news.ycombinator.com | 2024-02-23

    supports WebGL over SSH/MoSH

    https://www.brow.sh/docs/introduction/ :

    > The terminal client updates and renders in realtime so that, for instance, you can watch videos. It uses the UTF-8 half-block trick () to get 2 colours from every character cell, thus simulating basic graphics.

    https://github.com/fathyb/carbonyl :

    > Carbonyl originally started as html2svg and is now the runtime behind it.

    Always wondered how brew.sh added the brew sprite there; that's real nice.

    TIL that e.g. Kitty term can basically framebuffer modified Chrome?

    https://github.com/chase/awrit :

    > Yep, actual Chromium being rendered in your favorite terminal that supports the Kitty terminal graphics protocol.

    FWIW Cloudflare has clientless Remote Browser Isolation that also splits the browser at the rendering engine.

    A TUI Manim renderer would be neat. Re: Teaching math with Manim and interactive 3d: https://github.com/bernhard-42/jupyter-cadquery/issues/99

    What would you add to make it easier to teach with this entirely CPU + software rendering codebase?

    What prompts for learning would you suggest?

    - Pixar in a Box, Wikipedia history of CG industry: https://westurner.github.io/hnlog/#comment-36265807

    - "Rotate a wireframe cube or the camera perspective with just 2d pixels to paint to; And then rotate the cube about a point other than the origin, and then move the camera while the cube is rotating"

    - OTOH, ManimML, Yellowbrick, and the ThreeJS Wave/Particle simulator might be neat with a slow terminal framebuffer too

  • MeasureIt_ARCH

    MeasureIt_ARCH is an addon for Blender, that adds tools to create design documentation and technical drawings that can be previewed within Blender's 3D viewport, and exported as images, vector graphics or .dxf files. Read the Doc's here:

    There is quite a few "code" CAD's around https://github.com/Irev-Dev/curated-code-cad. Cadquery has contraints but isn't really a DSL.

    • Project mention: Show HN: Flyde – an open-source visual programming language | news.ycombinator.com | 2024-03-07

    As a visual person (traditionally trained as a graphic artist), I've wanted this sort of thing for a long while, and I've been trying to use it for 3D.

    Surprisingly, there are multiple specialized tools for this:

    - https://www.blockscad3d.com --- an adaptation of Google's Blockly to OpenSCAD

    - https://github.com/derkork/openscad-graph-editor --- wires and nodes, it has the advantage of exposing _all_ of OpenSCAD's commands (the above has a subset)

    - https://github.com/Tanneguydv/Pythonocc-nodes-for-Ryven --- a module for using PythonOCC in Ryven --- when I finally succeeded, I found the language inscrutable, even when provided w/ quite nice examples (definitely a failing on my part, not that of the tool)

    - https://github.com/graphscad/graphscad --- it took a long while for the source code for this to be made available, and for a while it had compatibility problems (why was "cube" redefined?) --- probably defunct for political reasons, it had some interesting ideas, in particular the ability to have custom icons for modules

    - https://www.nodebox.net --- if memory serves I got hung up by not easily being able to do 3D, and when doing 2D having precision problems (or maybe that was Processing.org)

    and I've been using these tools to make various things:

    https://willadams.gitbook.io/design-into-3d/3d-project

    (and maybe eventually I'll finish something)

    The problem I've been running into is there doesn't seem to be an answer to the question:

    "What does an algorithm look like?"

    I recently had occasion to mention Herman Hesse's _The Glass Bead Game_ (also published as _Magister Ludi_) and I'll bring it up again --- what is a meaningful graphical representation of a program?

    The Drakon folks argued that there should be one true path but that's not really communicative and I would note that if this was a simple thing it wouldn't be decades since I last saw a physical Flowcharting Template:

    https://americanhistory.si.edu/collections/object-groups/flo...

    (and it's pretty rare to even see a well-done electronic drawing of a flowchart since Visio made its splash and vanished into the bowels of Microsoft)

    The main problem seems to be one of expressiveness not scaling up well, hence:

    https://blueprintsfromhell.tumblr.com/

    https://scriptsofanotherdimension.tumblr.com/

    Presumably, one doesn't want to define modules/variables unnecessarily --- but the question becomes where is that boundary?

    If you define too many, then you're back to the "wall of text" which one was trying to avoid (but wrapped up in nice boxes with some lines or shapes), and if one doesn't use them (well, look at the pretty/awful images in the links above).

    Ideally, a well-coded visual program would have a pleasing aesthetic appearance which is expressive and communicates flow and function, and I've tried for that at:

    https://willadams.gitbook.io/design-into-3d/programming

    (though I wish that there was an easy way to export an SVG version of a program)

    I believe that what is needed here is some graphical equivalent to Literate Programming: http://literateprogramming.com

    Is there a nice GUI toolkit integration which would allow making a graphical application with this? I have an idea I want to try it which might be a good fit.
