gaussian-splatting
Images or video to 3D Gaussian splats plus a refined mesh. Full-scene and per-object
capture. Emits a collision proxy aligned to the visual splat, so a reconstruction is
usable in a PhysX scene without re-authoring it. FVDB, COLMAP, Kaolin.
heatmap_kit
Real-time contact heatmaps, heat diffusion running as NVIDIA Warp GPU kernels.
Scale-aware re-baking keeps the radius physical when a stage is authored in mm
instead of m. Split out of gaussian-splatting into a standalone extension with an
engine-agnostic backend and isolated UI.
agv_motion_kit
Path authoring with record/playback for AGVs and forklifts. Rear-steer kinematics,
virtual-commissioning-style replay. Follow controller is a progress P-controller;
true lookahead is still deferred.
crane_rope_simulation
Heavy-lift crane with deformable rope on PhysX 5 FEM. Ships a tuning extension plus a
root-cause writeup on rope instability under load.
Factory twin automation. Pick-and-place built on Isaac Sim's manipulator framework (RMPflow, SurfaceGripper, 10-phase task state machine), with OmniGraph-driven conveyors. The stage is the team's; the automation layer on top is mine.
Regression gates. Headless SimulationApp + Replicator runs that are bit-for-bit
reproducible, so a physics change that shifts contact results gets caught before merge
rather than in a client scene.
Condition monitoring. GPU synthetic telemetry (RAPIDS cuDF/cuML, CuPy) to Parquet and MQTT, bridged onto the Isaac Sim carb message bus. The predictive-maintenance and Triton Inference Server parts are NVIDIA reference workflows I worked through, not things I shipped.
