🫧 Soft Body Physics

A real-time Soft Body Physics simulation built with C++ and SFML 3.0, featuring jelly-like objects that stretch, squish, and wobble using a mass-spring system.

✨ Features

• Mass-Spring System — each blob is a grid of point masses connected by structural, shear, and bend springs
• Realistic Deformation — blobs stretch and squish on impact, then spring back
• Gravity & Bouncing — full gravity with energy loss on wall/floor collisions
• Grab & Throw — drag any blob with the mouse and fling it across the screen
• Explosion Mode — launch all blobs into the air simultaneously
• Pin Points — pin individual mass points to anchor blobs in mid-air
• Spring Wireframe — toggle spring visualization to see the internal structure
• Multi-color Blobs — 5 rotating colors, randomized grid sizes
