C++ code is out! The Signed Heat Method has been added to geometry-central. In 3D, compute generalized SDFs to point clouds, triangle meshes, and polygon meshes. The method should "just work" on geometry with holes, intersections, nonmanifold-ness, etc. Links below 🔽

Demo projects here: The demo projects let you try things out right away: load your own data, play around with constraints, export solutions. I also included a Blender file with the shader I used to make our paper figures. Enjoy!

Do the point cloud methods make sense for 3D Gaussian splats?

Nicole Fengvor 1 Jahr

Haven't tried gaussian splats, but in principle the method should work as you have normals for the geometry - which for gaussians might be done by taking a gradient where you've deemed your zero level set surface to be. Might be some finicky details to figure out.

incredible! I'll see if I can replace CGAL's AlphaWrap with it (for offset surfaces)

Super clean and efficient meshes by an AI? YES! The typical 3D Generative AI solutions produce lots of artifacts and usually way to many polygons due to volumetric approaches. In comparison “MeshGPT creates triangle meshes by autoregressively sampling from a transformer model that has been trained to produce tokens from a learned geometric vocabulary. These tokens can then be decoded into the faces of a triangle mesh. This method generates clean, coherent, and compact meshes, characterized by sharp edges and high fidelity.” Surely it is limited by the trained vocabulary but various versions can be trained for specific sets to create generative model libraries for certain object groups. Very promising approach with the high quality.

Adobe is entering the image-to-3D game! Their new method, LRM, can create high-fidelity 3D meshes from a single image in just 5 seconds 🔥 It's trained on 1 million objects and is able to generate objects from real-world images and generative AI models.

It’s really cool to see “legacy” players in geospatial like ESRI adopt 3D gaussian splatting in ArcGIS. Radiance fields are v. complementary to point clouds and textured 3D meshes — exceedingly human readable and much closer to reality than anything else.

The subject of Sacred Geometry is FAR MORE IMPORTANT and RELEVANT than many people realize. Sacred Geometry holds the key to what has been called free/unlimited zero point energy technology. The cabal knows this and keeps it hidden and to themselves so they can keep us enslaved Sacred Geometry is like the signature and fingerprint of God.

To support massive, high-fidelity worlds, our engine implements an efficient LOD strategy with a cloud transcoding system that streams meshes and textures, even on lower end mobile devices. We are expanding this framework to AI upsampling of 3D worlds from prompts. In this preview video below, with a single user prompt, our 3D upsampling technology updates the geometry and texture to transform the classic Roblox game Crossroads into a fantasy world with rich organic detail. 3/4

📢Happy to present Convex Splatting, a novel way for 3D reconstruction based on 3D smooth convexes. For the first time, a splatting-based method reaches the quality of NeRF sota methods but with real-time rendering and few primitives!! I expect this to replace Gaussian splatting for 3D in the coming months. CODE RELEASED TODAY! joint work with collaborators from Université de Liège Visual Geometry Group (VGG) , KAUST Computer Vision Lab (IVUL) a thread 🧵 1/n

Curve hair, but you can set different meshes per curve strand! And have options to adjust them. And its using the flat wrapping method so its easy to work with! This is the hair workflow i've wanted for over 7 years, and it can finally be built #b3d

✏️Tutorial on how to achieve the eyeball effect: This effect is achieved by adding 2 meshes that have inverted normals on them! One is for the whites of the eyes and one is for the iris itself. You can see how the meshes look like in the video below.

New open-source 3D world-generation model. I'm rendering a couple of worlds in the video, so check it out. You'll find the GitHub and the Hugging Face links to the model below. This is a multi-modal world model that you can use for a bunch of things: • To generate new worlds • To reconstruct worlds • To simulate 3D interactive worlds from a prompt, images, or a video You can edit the 3D outputs in Unity and Unreal Engine (they export as meshes, 3DGS files, and point clouds). You can also generate 3D characters in the world and walk around. Pretty fun stuff!

Check this out. No Booleans, SDFs, or anything fancy. Just setting the normals via geometry nodes. And the setup is right in the 4.5 release notes! The new "Free Normals" option helps this calculate nice and fast.
