Variables
| Type | Name | Description | |
|---|---|---|---|
   |
double | PelvisAdjustmentErrorTolerance | Specifies the pelvis adjustment distance error that is tolerated for each iteration of the solver |
   |
FVectorRK4SpringInterpolator | PelvisAdjustmentInterp | Specifies the spring interpolation parameters applied during pelvis adjustment. |
   |
double | PelvisAdjustmentInterpAlpha | Specifies an alpha between the original and final adjusted pelvis locations This is used to retain some degree of the original pelvis motion |
   |
double | PelvisAdjustmentMaxDistance | Specifies the maximum displacement the pelvis can be adjusted relative to its original location. |
   |
int32 | PelvisAdjustmentMaxIter | Specifies the maximum number of iterations to run for the pelvis adjustment solver Higher iterations will guarantee closer PelvisAdjustmentErrorTolerance convergence at the cost of performance |
