  1. Catchwater The GameInteractive Particle-Based Fluid Simulation Modeling Water Flow Through Pipes Ken Brooks and Brian Clipp May 9, 2006

  2. The Game

  3. Demonstration

  4. Pipe Section Modeling

  5. Sliced Cylinders

  6. Catchers • Square at top, round at bottom • Interpolate in 4 strips per edge

  7. Modeling the Structure • 24 possible orientations of a pipe • How do its connectors connect? • Solution: • Have a unit vector for each connector • Keep a quaternion per pipe • Maintained as user rotates while placing • Multiply by that quaternion for true direction

  8. Pipe connector data • Tee • 0, 1, 0 (up connector) • 1, 0, 0 (right connector) • 0, -1, 0 (down connector)

  9. Smoothed Particle Hydrodynamics

  10. Fluid Dynamics Conservation of Mass Conservation of Momentum Particle Accelerations

  11. Pressure, Visosity and Surface Tension Forces Particle Density Calculation Pressure Force Calculation Color Field Surface Tension Force Viscosity Force Calculation

  12. From Particles to Pipes • Particle simulation is inefficient for horizontal flow • Capture and count particles at inflow • Generate particles at outflow

  13. User Interface Experience • Particle simulation is beautiful! • Free viewpoint movement is vital • ESDFWR are effective rotation controls • Not very satisfactory position controls
