Bodytalk V2 - The Extended Skeleton Edition

The obvious question: Does tracking 145 bones kill your frame rate?

During beta testing on a standard Ryzen 5 with an RTX 3060, BodyTalk v2 ran at 90 FPS while tracking two full skeletons. The developers achieved this by using "LOD Bone Culling" – meaning the system prioritizes the hips and spine (Spine LOD 0) and degrades the fidelity of the toes (Spine LOD 3) when the user is moving quickly.

Memory footprint increased from 85MB in V1 to 210MB in V2. The trade-off is worth it for the sheer volume of anatomical data available via the AnatomyBuffer.

Vtubers and virtual production actors struggle with "dead hands" and "floating feet." The Extended Edition allows for natural hand resting poses and proper foot placement on virtual stages. It integrates seamlessly with LiveLink for Unreal Engine 5.4+, enabling cinematic-quality mocap without a $50,000 suit.

This is the "Talk" in BodyTalk. With the Extended Skeleton, we incorporate specific tactile cues that "wake up" dormant areas of the bone. By stimulating the periosteum (the membrane covering the bone), we send high-velocity signals to the brain. This refreshes the brain's map of the body, instantly improving range of motion and stability.
