Daz 3D’s Post

Last week we talked about face reconstruction but how about something much more detailed like hairs? Like skin you have complex geometry, subsurface scattering and a lot of movement! Well a new challenger appears Have a look at "Gaussian Haircut ✂️ Human Hair Reconstruction with Strand-Aligned 3D Gaussians" a new paper presented at ECCV2024 by the team at ETH Zürich, Max Planck Institute, Meta and Technische Universität Darmstadt. They introduce a new hair modeling method that uses a dual representation of classical hair strands and 3D Gaussians to produce accurate and realistic strand-based reconstructions from multi-view data. In contrast to recent approaches that leverage unstructured Gaussians to model human avatars, their method reconstructs the hair using 3D polylines, or strands. This fundamental difference allows the use of the resulting hairstyles out-of-the-box in modern computer graphics engines for editing, rendering, and simulation. Their 3D lifting method relies on unstructured Gaussians to generate multi-view ground truth data to supervise the fitting of hair strands. The hairstyle itself is represented in the form of the so-called strand-aligned 3D Gaussians. This representation allows us to combine strand-based hair priors, which are essential for realistic modeling of the inner structure of hairstyles, with the differentiable rendering capabilities of 3D Gaussian Splatting.

🥊 Midjourney vs. DALL·E Which is the best text-to-image creator? Here is an example how they perform with the same prompt. The Prompt: Create an image that achieves undoubted photorealism, capturing the intricate imperfections of a human subject. The skin should have a complex texture map that includes pores, moles, fine lines, and slight variations in pigmentation, with a multiscale roughness map to simulate varying levels of shininess and matte across the face. Implement advanced subsurface scattering techniques to emulate the semi-translucent property of skin with irregular diffusion, especially around the nose and ears. Render the hair with a physics-based simulation that reflects the natural grouping and adhesion of wet strands, varying in transparency and glossiness. Each strand should catch and diffract light based on its relative wetness. The eyes should have a deep-set look, with a multi-layered iris texture that includes fine fibrous details and an irregular, non-uniform catchlight reflecting a realistic light environment. Include micro-veins in the sclera with subtle color gradients to mimic the natural variance in human eyes. Ensure facial symmetry is not absolute, introducing micro-variations in the position and scale of features to reflect the natural asymmetry of a real human face. The lips should have a detailed texture map that defines dry versus moist areas, causing light to scatter differently across them. Employ a dynamic range lighting setup that casts defined but soft-edged shadows to sculpt the facial features, using a combination of a strong key light and a softer fill light to create a realistic interplay of light and shadow. Include ambient occlusion particularly in areas where the hair casts a shadow on the forehead, and where the neck meets the jaw. The final render should incorporate environmental lighting effects, reflecting subtle colors from the surroundings onto the skin, and should be free from any noise or rendering artifacts. Capture this with the precision of a full-frame sensor camera, through an 85mm prime lens set at f/2.0 for a shallow depth of field, rendering a softly blurred background that complements the sharply focused subject --v 6

I created this Quixel Mixer Skin Palette to provide a variety of human skin tones, undertones, and features like skin damage, freckles, and moles for my 3D asset production projects. Let me know if you have a specific use case for this & similar 3D production pipeline tools: I am happy to make it 1000 times superb for your own projects. Here’s how I use it: SKIN TONE LAYERS: Activate one base color of your choice. Adjust the opacity to add a skin undertone. SKIN UNDERTONE LAYERS: Activate one undertone layer to change the resulting skin color. You can adjust the opacity for multiple undertones, but for PBR material export, using just one undertone is recommended. SKIN DAMAGE, FRECKLES, MOLES: Activate these layers as needed. They are placed at the top so the skin tone and undertone layers can still show through. For human and humanoid characters with different undertones on different parts of the face and body, create the model with relevant material IDs for each location. For example, if a face has dark pink undertones on the chin and nose, assign a 'pink undertone' material ID to those areas and a 'blue undertone' material ID under the eyes. In the Quixel Mixer Skin Palette, design and export your customized skin materials with the specific undertones. Apply these customized skin materials to the relevant locations on your 3D model. For a procedural material workflow, create and export individual skin damage materials for your preferred skin tones and undertones. For procedural material workflow, use the customized skin palette material exports (tone material, undertone material, damage material, freckle material) in applications like Blender Shading Editor, Geo Nodes, Substance Designer, and similar tools.

Diamond Cut Craftsmanship, 3D Diamond Hologram? – Part II -- Yesterday I posted a genuine face-up technical picture of our Octavia diamond and asked if anyone might notice an optical phenomena occurring on its parallel face-up position. No-one picked up the glove… So let me try to explain. We have quite a few technology tools that can assist in analyzing diamond lapidary works. Most will depend on the few non-contact scanners available on the market like Sarine Diamension® and Lexus Helium etc… but what to do with their realistic margins of errors? The companies mentioned admit to some minimal margins of error in their 3D diamond scanning (I will not get into the numbers as they are not really relevant for this post), lets take a scenario of our subject.. Each Octavia diamond possesses 57 facets including the table, now imagine each single one of those facets is measured with a tiny error translating its light measured data erroneously while realistically light rays have no deviation… could be a messy affair! In order to surpass such hurdles, lapidaries must tackle such tech limitation by forfeiting tech data at a certain apex for genuine intellectual data. This is where product differentiating becomes interesting and unique! Did you know diamond are able to display a 3D hologram via precision craftsmanship alone? A genuine signature for mastership. In this picture collage, I am displaying the Octavia from Part I encircled by a red frame displaying its unique 3D optical hologram composed by the human ability to mirror crown & pavilion symmetry arrangements. Will be continued… ……………………. #gemconcepts #optical #3Dopticalsymmetry #opticalsymmetry #diamonddesign #cuttingdiamonds #diamondstories #uniquediamonds #therealrarediamonds #stepcut #asschercutdiamond #squareemerald #opticalphenomena #octaviadiamond

One of the many things that I love about being a patient at @gerrishmedesthetics_az is that @drscottgerrish keeps up on the latest and greatest in aesthetic technology. He is the guru on laser treatments and travels around the world, teaching and creating protocols for these lasers. Now… Dr Gerrish has brought in this new 3D technology that captures your face in every dimension.. it sees what your skin looks like below the surface, and measures the dimensions of your face. This allows you and the doctor to see measured results. Why is this beneficial? *If you have cool sculpting, the results can be deceiving. Now you will actually be able to measure the exact results. *If you think that the filler in your lips have dissolved, that can also be measured Just a few examples.. These results don’t lie. It will help both you and the Gerrish team achieve the best results. This is a $300 value that is free with an appointment booked in the month of September. You will also receive 15% off your first visit just mention Jules go to https://lnkd.in/g_MJtqgK to schedule your appointment

Dropping 2D videos of #NeRF scans back into #GenAI with a few prompts can produce striking eye candy. This example was captured through the glass of a display cabinet by pushing my phone lens flush with the glass (to reduce reflections). After uploading and rendering 3D in LumaLabs.ai, I keyframed a new path through the display cabinet and rendered a 4K video. I then dropped this into Kaiber.ai video to video setting with these prompts: Subject Insert realistic eyeballs in these skulls and make them follow the camera, the sword to glint with shiny reflective gold and the faces of each skull to smile broadly, background to arc neon blue, purple, red with static electricity Art style photo taken on film, film grain, vintage, 8k ultrafine detail, private press, associated press photo, masterpiece, cinematic Not quite a perfect match, but its early days.
