nice, I always wanted something like this for "movie/sci-fi tv" style presentations. no idea what I'll do with it though.

interesting -- but i am not sure one would want to build an entire presentation with a lot of 3D effects and animations IMO this would be a good tool to have among many -- to use judiciously only when needed. -- Maybe if we could somehow integrate this capability into existing tools (not sure how). (I think MS Powerpoint has some 3D objects and animations -- but I dont see it used much in business. I used it once for a fancy presentation and it worked fine. It does support "Morph" transition so you can copy a slide 1it ha 3D object and move / scale / rotate it in 3D ... and powerpoint will interpolate it for you. you can also animate the objects - like apply a 3D rotation.)

    Right. I think if it’s a presentation about the object then there could be plenty of applications for this. I will definitely be trying it.

Looks pretty cool. Too bad immersa.app seems to be down.

You can do this kind of thing in Apple Keynote. It's one of those powerful features that you find in Apple software but for some reason they keep hidden. https://support.apple.com/en-gb/guide/keynote/tane2b2f4354/mac https://support.apple.com/en-gb/guide/keynote/tane2b2f4354/m... You can use "Magic move" to do the kind of stuff that Immersa is doing.

Thats quite an impressive amount of functionality for not much code. Tokei says 4.4k sloc in the ui dir which contains the editor implementation. I was over 25k sloc for a less ambitious editor in typescript recently. I'm also a bit jealous of how clean the reframe usage model is, i really liked the dominoes explanation when i first learned about it. https://day8.github.io/re-frame-wip/dominoes-60k/ https://day8.github.io/re-frame-wip/dominoes-60k/

  > impressive amount of functionality for not much code. Tokei says 4.4k sloc Curious about your process here. Do you evaluate repositories this way as a habit? Is there a Web interface for such tooling? Visualization? What are your heuristics to evaluate a project this way?

    I don't usually so i don't know unfortunately, i was just curious in this case

Looks pretty cool, congratz. Shaders are coming with the model right ?

The Readme is substantially LLM generated, yeah? Something about LLM readmes leave me cold. Including stuff like this feels like the sort of typical LLM time-wasting stuff that they output these days: Add 3D Model: Click "3D Model" → "Add 3D model (.glb)" → Select your file Add Image: Click "Image" → "Add image" → Select your file Add Text: Click "Text" or press T to add 3D text To add a 3d model I click "3d Model" and then "add 3D model" and then add my 3d model. Very clear, but not usually what I look for in a readme. LLMs love this sort of stuff though. To compare, the initial Readme (I guess this is a default re-frame readme?) doesn't have this same LLM vibe at all: https://github.com/ertugrulcetin/immersa/blob/7f585f5f544e2f27abb8b8df7cdbb5c49702cd39/README.md https://github.com/ertugrulcetin/immersa/blob/7f585f5f544e2f...

  Yes, sorry about that if it annoyed you. I was too busy to write a good human-sound readme. It was an old project, and I wanted to release it as open source as quickly as possible.
  - roywiggins 10mo ago
    I think I don't mind LLM generated documentation per se if they're marked as such up front! It's more when I get halfway through and realize that this is probably an LLM output that I get annoyed.

      100%, it's all about disclosure to manage expectations.

That reminds me a lot how one presentation from the Nvidia GTC was made! https://youtu.be/1qhqZ9ECm70?si=ESfE4ITfmSrq508y https://youtu.be/1qhqZ9ECm70?si=ESfE4ITfmSrq508y Truly impressive video.

Can you give some thoughts on why you decided for a UX that each transition required a new slide? If you had an animation heavy presentation, I can imagine there would hundreds or thousands of slides. On-click or timed animations in existing presentation software exist in a timeline within a single slide.
- ertucetin 10mo ago
  Hey, thanks for the feedback. Honestly, I don't know. It seemed pretty easy to do that way at that time. But I'd accept PRs that could improve the product.

  > why you decided for a UX that each transition required a new slide? Not OP but I imagine conceptually for a newcomer to 3D or animation that's actually great onboarding. They do not have concepts of keyframes but they do know about slides. When it becomes really long and complex... then IMHO it's not for the same audience anymore. They can install Blender or whatever other tool they need.

Nice! Very interesting idea and seems well executed in the demo video. “3D Presentations” seems like a very strange use case though. I actually think you could pivot this to be a very simple “3D movie maker”! Just make the presentation autoplay, allow different durations for each slide, different interpolation strategies… then you have a super clean and minimal 3D video maker!

I could use a 3D powerpoint. Even the most basic, boring arrows and boxes will look better in 3D. Some of the slides in a preso I use almost daily would convey the message better if they were in 3D.

This looks great! Would be good to download a ready binary too. I used to make similar in powerpoint, surprisingly it has good svg/obj support, with some creativity you can do wonders. Can the output be exported to common file types? Videos or similar, it would better imo.
- utopiah 10mo ago
  > Would be good to download a ready binary too. Binary? It's Web based so IMHO download a .html that packages it all including assets, would be a lot easier to do to keep it cross platform. Also yes it'd be very valuable because we all remember great presentations grinding to a painful halt because the connectivity is poor.
