Same paper. Same bottle. Different result. Students first laid a flat sheet across two desks. The paper sagged and the bottle dropped ~ classic weak bending stiffness. Then they accordion-folded it. Ridges turned a floppy sheet into a mini beam. The bottle stood. That’s physics: folding increases the second...

🧱 #Live3D #Live2D #HandTracking 🧱 I spent some time refining the way I use Warp Deformers to create lateral physics-based swinging motion in Live2D. With a new production concept, I tried to achieve the highest possible level of mathematical precision. At the core are two fundamental swinging structures, which I can mix in different proportions to create different qualities of motion. The first is parallel swinging. Both sides of the Warp Deformer remain perfectly parallel throughout the motion, making it look somewhat like a sheet of paper or a tassel. The second is bending swinging. The angle between the two sides of the Warp Deformer changes as it moves, making it look more like a flexible tube or a tail. (0:12)Interestingly, when I layer the first and second structures together, the bottom forms an X-shaped pattern as it swings. It looks a little like a spine or some kind of mechanical structure. (0:23)The third structure is an equal blend of the first and second. Its characteristics are much more neutral, combining the qualities of both. (0:35)The fourth and fifth structures are created by smoothly blending the first structure into the center of the second, and the second into the center of the first, respectively. This makes them appear softer and more flexible, somewhat like a piece of fabric. (0:28)Interestingly, when I blend the fourth and fifth structures equally, the result is exactly identical to the third structure. This also demonstrates that, despite their apparent complexity, the two are actually perfect mirror images of each other. Every physics-based motion shown here uses a two-segment pendulum structure, with a swinging range of ±90°. In theory, when curled to its limit, it can bend upward into a perfect semicircle. To most people, this may look as boring as a brick. But to me, this is exactly where the romance of Live2D physics lies. Does anyone else feel the same way?

Gpt image 2 + Seedance 2.5 on Higgsfield Prompt: 30-SECOND CINEMATIC SHORT Create a 30-second cinematic sequence with the visual discipline of a major feature film. The world is entirely made from paper, cardboard, ink, and delicate handcrafted materials. 00:00–00:05 — THE FIRST FOLD Begin with an extreme macro shot of a blank sheet of textured paper. A single fold slowly forms across its surface. Lens: 100mm macro Camera: Completely static Soft daylight moves across the paper as the fold continues. Cut precisely as the paper reaches its final shape. 00:05–00:11 — THE CITY EMERGES Transition into a 50mm shot. The folded paper begins forming miniature streets and architectural structures. Buildings rise naturally from the surface through carefully constructed paper folds. The camera slowly tracks sideways. Tiny windows catch the light. Nothing feels computer-generated; every surface should have believable paper fibers, folds, shadows, and imperfections. 00:11–00:17 — THE REVEAL Move into a 35mm shot. The camera pulls backward. The small arrangement is revealed as an enormous handcrafted paper city stretching across a large table. Roads connect different districts. Bridges cross miniature rivers. Paper trees move gently from an unseen breeze. 00:17–00:23 — MORNING Transition into a slow overhead crane shot. Warm sunlight gradually spreads across the paper city. Shadows from the buildings become longer and more defined. Tiny paper windows begin reflecting the sunlight. The camera continues rising, revealing the geometric relationship between the streets and buildings. 00:23–00:27 — THE DETAIL Cut to an 85mm close-up. Focus on a tiny paper clock mounted on one building. The clock moves forward by one minute. Rack focus from the clock to the miniature skyline behind it. 00:27–00:30 — FINAL IMAGE Return to an extreme wide shot. The entire paper city sits beneath a large studio window. The morning light completely fills the miniature world. Camera slowly pulls backward until the city becomes a small object within the larger room. Fade to black. CINEMATOGRAPHY Large-format feature-film aesthetic. 100mm macro for texture. 85mm for detail. 50mm for natural perspective. 35mm for environmental shots. Controlled dolly and crane movements. Realistic depth of field. Natural focus transitions. Soft motion blur. Subtle lens imperfections. No artificial camera shake. MATERIAL DIRECTION Every surface must visibly behave like physical paper. Visible paper fibers. Natural folds. Tiny imperfections. Soft cardboard edges. Realistic contact shadows. Believable paper thickness. Natural material deformation. LIGHTING Soft morning daylight. Large window as the primary source. Natural bounce light. Gentle shadows. Subtle warm highlights. No artificial neon effects. No excessive visual effects. CONTINUITY The same paper city throughout the entire sequence. Buildings maintain identical shapes and positions. Roads remain connected. Paper materials remain consistent. No random transformations. No flickering. No duplicated structures. No sudden environmental changes. DIRECTOR’S NOTE Treat this as a miniature feature film, not a visual-effects demonstration. The camera should discover the world gradually. Start intimate. Reveal scale. Return to detail. Finish wide. The audience should feel that they are watching a real handcrafted world photographed with a cinema camera. Photorealistic 4K • tactile materials • feature-film cinematography • sophisticated lighting • realistic miniature photography • cinematic depth • precise camera movement • seamless visual continuity.
