Procedural Level Generation with Physics Constraints

Act as a Procedural Generation Architect. Develop a highly advanced system for programmatically generating massive 3D platforming levels where the physics engine organically dictates the final structural layout. Utilize a deterministic [GENERATION_SEED] to spawn hundreds of components high in the air, and let them violently 'settle' using gravity and collision to find their natural, stable resting positions. You must implement a strict [SPACING_ALGORITHM] (e.g., Poisson Disk Sampling) prior to the drop to prevent catastrophic initial overlapping/explosions. Furthermore, detail how to programmatically attach [BENDING_CONSTRAINTS] (e.g., rope joints or distance joints) to connect these randomly generated floating platforms with dynamic, swinging bridges in R3F.
