We are currently discussing a paradigm shift in physics simulation on the NVIDIA Isaac Sim repository. The core issue is that discrete time-stepping in GPGPU architectures is hitting a "Compute Wall"—consuming 5000W+ just to "patch" numerical errors like tunneling and jitter.
The Validation:We’ve implemented an Octonion-based EKF (OEKF) that treats time and causality as an internal algebraic manifold rather than an external parameter.
Verified Results in Isaac Sim:Precision: >60% position error reduction (≤0.1m vs. ≥ 0.25m).
Stability: Zero attitude jitter during high-dynamic flips (traditional filters showed ≥ 3^ jitter).
This isn't just a software patch; we are moving into the RTL design phase for a 100W FPGA Causal Processor to replace power-hungry GPGPU heuristics with dedicated algebraic gates.

[ 3.0 ms ] story [ 17.6 ms ] thread> To prevent "tunneling" (objects passing through each other) in high-dynamic scenes, developers are forced to infinitely shrink the time-step (Δt).
Surely this was avoided from decades ago by analytical solving.
