Yes. That is the plan. I’ll make a tutorial about how you can generate datasets of an interior with Camera Array Tool.

@ thank you, I have bought your plug-in, so tutorial will be useful

Yes. My intentions is to make a separate tutorial on making of the interior datasets. It will come later.

True! That's a good question. I forgot to provide a file size comparison. Since the Batman run loop was created using the ADC profile, the PLY files are comparatively much lighter. approx. 7Mb per PLY file. If you want to download the animation sequence from this sample package, you can get it here: nappiboxi.net/downloads/BatmanRunloop_4DGS.zip

@@OlliHuttunen78 Wow! awesome thanks!

Nvidia RTX 3070 with 8Gb vram.

Really? Interesting! How do you do that? How you change the images during the training?

@@OlliHuttunen78 No, images need to be exchanged prior to importing them into PostShot. For example, you can export images for frame 1, along with the PLY point cloud and COLMAP camera poses. Then, you can copy images for, say, frame 10 into the images folder. If they are named in the same manner and imported into PostShot, you should be able to train successfully on frame 10, even if your PLY point cloud does not match. I'm not sure if this has any practical use, and I'm surprised it actually works.

In Postshot you can export these animated camera movements as alembic .abc format. Perhaps there is some way to import or convert these camera files in such format that 3Ds max will understand.

Like said in video it is a upcoming feature. The update where this 4DGS feature will be is coming soon. If you already bought this add-on you will get the update for free when it is ready.

@@OlliHuttunen78 thank you

I understand the idea and such a technique would certainly be exactly what the 4DGS compression method is intended to be. In this sequence technique, however, all the Gaussians are new and the model is completely retrained in each frame. And that is currently the only way to produce these PLY sequences for regular Postshot users at least. This thing will certainly develop and change soon and we will get a similar process as in video compression and only moving Gaussians are changed. Those that are in place will stay in place. Thus, the size of the Dynamic Gaussian Splatting file will certainly decrease as soon as such a format is developed.

Yes! Gracia is interesting VR solution.

Yes. I’ve been thinking about that point also. Currently there are not much use to generate dynamic Gaussian Splatting for games since polygon solutions can do it so much better and lighter at the moment. I can only see that these gaussians could come usable on simulations like smoke or explotions or something that is very heavy to render with traditional methods.

Spectacular video. Thank you very much for the effort in explaining how the 4dgs works. I am experimenting with Trellis, a Gaussian Splat generator through images, post-shot, and then viewing it in MetaQuest via Gracia VR. I am eager to try it.

@@OlliHuttunen78 thank you Olli!

Sure the batch Trainer which I made works also for regular images. It just takes longer time to train them because postshot needs to make a camera tracking phase to them. Just put your images to numbered folders and the batch trainer will automate this task. But be aware also that error issue which I mentioned in video. Postshot is not that stable yet. It can crash during the training. So you at least need to check out the process on time to time.

@OlliHuttunen78 I see, thank you for your reply :) This works well if you already have the image sets and only want a .ply file in the end. I was more interested in using video as an input and I would like to get a .psht file (with "Store Training Context" enabled). Is this possible with a script?

Yes. This batch trainer of mine is designed to export PLY sequeces. But you can save Postshot own native format .PSHT trough the command line also. Just check out the dokumentation in Postshot page here: www.jawset.com/docs/d/Postshot+User+Guide/Command-line+Interface
