Softbody Simulator

This is a gpu softbody simulator using webgl2.

Data

The world will be divided into individual "Particles". Each "Particle" will have an ID (array index), and the following values:

• Deleted: u8
• Position: i32x2
• Velocity: i32x2
• Connections:
  • Orthagonal (u32x4)
  • Diagonal (u32x4)

Any 0 values in the Connections will be ignored, as the zeroth particle will always be deleted.

Current Physics Simulation Method

At each physics step (600 steps per second), the simulator iterates over all the particles, and applies a force equal to (where c is the connection length, and d is the distance):

d^2 / c^2 - c^2 / d^2

This makes the softbodies much harder to compress.
