[1/4] I've just finished updating our VAT utils package for VFX Graph to the great VAT3.0 from @sidefxlabs. youtu.be/Ms41cq63dQw #madewithunity #Houdini #gamedev #indiedev

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: …lattinghtml-production.up.railway.app @theworldlabs @chaoyuaw @the_f_key

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

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

@KeJyunWu @unity Just.. wow 🔥🔥🔥

My new work, Second Nature, is on the way. Can’t wait to share more details with you all!! @unity is on fire 🔥 #madewithunity #unity6

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

😙 a glimpse of my new artwork for a dome project. Can’t wait to show it to you all!! @unity is on 🔥 🔥 #madewithunity

@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?

Deckard Renderer is a plugin for @Unity that I've made. It is mostly based on Unity Engine, but it tackles problems of physical simulation of depth of field, color response of most of the cameras out there, motion blur, and antialiasing, and also soft shadowing. Most of the problems that are crippling a realtime graphics rendering. It doesn't work in realtime, but it is extremely fast. You can render a photorealistic scene 25-50 times slower than realtime. That means that you have a reasonable times for rendering, and more interactive preview.

Experimenting with #GaussianSplatting for #VFX with @DigitalTwin Fast test on simple reflections. As reflections in gaussians are practically a duplicated mesh, I'm just duplicating AT_AT walkers and reversing them up-down. Not a perfect, but this was done in 30 minutes time. Scans were made with @Scaniverse app. Rendered in Unity with #DeckardRender. GSplats use @aras_p plugin for @unity

Mais là on vient de claquer un triplé NORMAL ? SVP C'EST CA MA FRANCE 🇫🇷💙 #AllezLesBleus #Paris2024

@maximebodereau Ohhh nice 😁 Merci

@AlexR4 again

Also looking for this!

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

@AlexR4 😘

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! iquilezles.org/articles/smin/ (new stuff starts about 1/3 into the article)

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

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

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.

Continuing my recursive subgrid exploration while starting the conception of a new data art project #glsl #shader #Houdini @sidefx @Shadertoy

VAST AI releases Triplane Meets Gaussian Splatting on Hugging Face Fast and Generalizable Single-View 3D Reconstruction with Transformers demo: huggingface.co/spaces/vast-ai… 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

Gaussian Splatting Unity HDRP Lit Shader and Re-lighting with Vol.Light range attenuation ! Update 02 Sun/point/area light's #madewithunity #GaussianSplatting #gamedevs #VFX #Unity3D #VR #LumaLabsAI @LumaLabsAI

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

@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 ;)

@AlexR4 @GabRoXR @LumaLabsAI @Polycam3D The Unity package expects splat PLY files with very rigid vertex layout, basically same as in the splat paper: including the (unused) normal and full spherical harmonics. You can also edit/cleanup splats in the Unity project directly, btw.

Have you made some #3D models with #gaussiansplatting using @LumaLabsAI or @Polycam3D ? Here is how you can now clean them up directly on the web: People nowadays call them "Splats". These 3D models have the advantage of being extremely light compared to polygon-based 3D models. You can use various apps to generate these assets like the one I mentioned above. Often what you need is just a video or a set of images that you can shoot directly from your phone. To my knowledge, none of those apps right now offer the ability to edit and "clean" the model you get.... UNTIL NOW! You can go to playcanvas.com/super-splat from @playcanvas import the splats you have downloaded and start cleaning it up directly on your #browser. After that the asset is ready to be exported as a PLY file Was this useful? Follow me for more content around #XR and #AI 😉
