FPBDJointUtilities::ConditionParentInertia

Increase the IParent inertia so that its largest component is at least MinRatio times the largest IChild component.

Windows

MacOS

Linux

Syntax

static FVec3 ConditionParentInertia
(
    const FVec3 & IParent,
    const FVec3 & IChild,
    const FReal MinRatio
)

Remarks

Increase the IParent inertia so that its largest component is at least MinRatio times the largest IChild component. This is used to condition joint chains for more robust solving with low iteration counts or larger time steps.

Returns

The max/min ratio of InI elements.

Parameters

Parameter	Description
IParent	The input inertia.
IChild	The input inertia.
OutIParent	The output inertia.
MinRatio	Parent inertia will be at least this multiple of child inertia
