Content Summary

The post is about a stress test of a physics-based cable system developed in Unity. The author tested 90 cables, each made of 20 rigidbody spheres, with real-time shadows and mesh updates every frame. While there was some stutter due to the high number of interactions, the author found it visually impressive and shared it to inspire others. They also promoted their game projects and encouraged community engagement.

Opinion Analysis

Mainstream opinion seems to be positive about the visual appeal and creativity of the cable system, with many users expressing admiration for the implementation. Some users suggested potential use cases for such a system, like snake or worm simulations. There are some debates around performance and optimization, with one user suggesting moving vertex updates to the GPU for better efficiency. Others commented on the visual style, comparing it to gummy snakes or Resident Evil 5. Overall, the discussion highlights both appreciation for the creative effort and practical concerns about scalability and performance.
