A real-time 2D simulation of a fabric mesh using spring forces and gravity. The simulation demonstrates elastic deformation, force application, and interactivity with nodes that can be dragged and linked to simulate fabric behavior.
- Gravity: A constant force applied downward on the fabric mesh.
- Springs: Each node in the fabric is connected to its neighbors using springs. These springs behave according to Hooke's Law, generating forces based on their displacement.
- Damping: A damping force is applied to the fabric to simulate realistic friction or air resistance.
- Node Interactions: Nodes can be grabbed and moved interactively, and links between nodes can be toggled with a right-click.
- Left-click to grab and move nodes.
- Right-click to unlink nodes from their neighbors.
- Drag nodes to change the shape of the fabric in real-time.
- Real-time updates with a fixed time step for physics simulations to maintain stability across machines.
- Node Rendering: Each node is represented as a circle on the canvas, and springs are drawn between neighboring nodes.
- Real-time Force Application: Spring forces, gravity, and damping forces are visually reflected in the simulation.
- Click-drag mechanics for easy manipulation of individual nodes.
- Right-click to unlink nodes and disrupt connections.
