[1/4] I've just finished updating our VAT utils package for VFX Graph to the great VAT3.0 from @sidefxlabs.

Spent months figuring out how to add dynamic lights to Gaussian Splats without surface normals.

Turns out? Just use the view direction. It's "fake" but runs at 60+ FPS and looks great:-)

Sometimes good enough is better than perfect.

If you're interested in learning more about fake lighting with Gaussian Splatting, you can read my research paper on this topic:

I rarely post AI stuff (even if I work a lot with it) but as @OlixOliver said, this one combines utility and ethics
I really like when AI is focused in pipeline production

[Oliver Pavicevic🇺🇦 @OlixOliver]

This is some useful and ethical AI usage. This is what an AI should be about. It simply generates material passes from photos. Pretty awesome if you want to do some de-lighting or create advanced materials. It still requires some of the manual work to make it work well. But it is a useful tool.

This year, with @BonjourLab we will support the great event @Mo_Plus_Design in paris 💪

@KeJyunWu @unity Just.. wow 🔥🔥🔥

[Alexandre Rivaux @AlexR4]

@KeJyunWu @unity Nice work 👏👏👏
I want to see more now 🤣

[Alexandre Rivaux @AlexR4]

@OlixOliver @janusch_patas @DigitalTwin @unity Your results are really nice 👍
Juste to be sure to follow you correctly on the pipeline. Basically deckard will work on the legacy pipeline in unity, handling the image camera realism. GS is handle with @aras_p implementation or this is also handle by deckard?

Mais là on vient de claquer un triplé NORMAL ?

SVP C'EST CA MA FRANCE 🇫🇷💙

@maximebodereau Ohhh nice 😁
Merci

[Matt DesLauriers @mattdesl]

Also looking for this!

[Alexandre Rivaux @AlexR4]

@maximebodereau Merci pour le partage 😁, c est ouf comment ça va vite la recherche dans ce domaine 🤩

Hi SDF friends, here's a full rewrite about smooth-minimums (soft blends/unions), where I introduce Normalization, Kernels, a circular smooth-min and an analysis of several blend functions. Hope you enjoy it!

(new stuff starts about 1/3 into the article)

[Alexandre Rivaux @AlexR4]

Hi @Magnific_AI, I juste have a quick question about your great tool (in fact two). Is there a plan for batching images to upscale/enhance or an API in the near future ? Would be great for animation

[Alexandre Rivaux @AlexR4]

This was such an avant-garde approach and we can see it now as the vid2vid is so much hyped in AI creation

[memo akten @memoakten]

I'm very happy that my 2017 experimental AI film "Learning to see: Gloomy Sunday" has been included in the "Early Pioneers of AI Art" collection by @jediwolf.

Custom GLSL Shader Modifiers for @Modyfi_ are super close to be release as an experimental feature. Replay or RT if you are interested on trying it out. Just image coding shaders inside a non-destructive / generative web tool which also leverage GenAI.

VAST AI releases Triplane Meets Gaussian Splatting on Hugging Face

Fast and Generalizable Single-View 3D Reconstruction with Transformers

demo: https://t.co/qB5Tp8Ih65

TGS enables fast reconstruction from single-view image. It builds the 3D representation upon a hybrid Triplane-Gaussian representation by evaluating a transformer-based framework, from which 3D Gaussians would be decoded

Starting the year exploring ideas on recursive subdivisions

Oh my... I wanted this feature for so long. I really need to test it

[Keijiro Takahashi @_kzr]

I'm trying out the custom HLSL node feature of VFX Graph (available from Unity 2023.2). Now I can extend VFX Graph with custom shader code.

@aras_p @GabRoXR @LumaLabsAI @Polycam3D Thank @aras_p for the explanation 👍💪
I also tried the edit capabilities on the package, which is great, I just wanted to check if there was en interoperability between the two ;)
