◆ CalculateSpringPropertiesWithBias()
| void SpringPart::CalculateSpringPropertiesWithBias |
( |
float |
inBias | ) |

Calculate spring properties based on frequency and damping ratio
- Parameters
-
| inDeltaTime | Time step |
| inInvEffectiveMass | Inverse effective mass K |
| inBias | Bias term (b) for the constraint impulse: lambda = J v + b |
| inC | Value of the constraint equation (C). Set to zero if you don't want to drive the constraint to zero with a spring. |
| inFrequency | Oscillation frequency (Hz). Set to zero if you don't want to drive the constraint to zero with a spring. |
| inDamping | Damping factor (0 = no damping, 1 = critical damping). Set to zero if you don't want to drive the constraint to zero with a spring. |
| outEffectiveMass | On return, this contains the new effective mass K^-1 |
