Class TwoBoneSolver

Namespace: ValveResourceFormat.Animation
Assembly: ValveResourceFormat.dll

Two-bone inverse kinematics.

public static class TwoBoneSolver

Inheritance

object ← TwoBoneSolver

Methods

HasChain(Skeleton, int)

Whether a bone has the parent and grandparent that form the chain to solve.

public static bool HasChain(Skeleton skeleton, int effectorBoneIdx)

Parameters

skeleton Skeleton

effectorBoneIdx int

Returns

bool

Solve(Pose, int, FrameBone, float, IKBlendMode, float)

Solves the two bone chain ending in the effector towards the target, in place on the pose. The chain rotation weight picks how the effector rotation is solved: 0 fully rotates the effector, 1 rotates the chain.

public static void Solve(Pose pose, int effectorBoneIdx, FrameBone targetTransform, float chainRotationWeight = 0, IKBlendMode blendMode = IKBlendMode.Effector, float blendWeight = 1)

Parameters

pose Pose

effectorBoneIdx int

targetTransform FrameBone

chainRotationWeight float

blendMode IKBlendMode

blendWeight float

Solve(Span<FrameBone>, ReadOnlySpan<FrameBone>, FrameBone, float)

Solves a three bone chain in model space towards the target, in place. Returns false for a degenerate chain.

public static bool Solve(Span<FrameBone> modelSpaceBoneTransforms, ReadOnlySpan<FrameBone> modelSpaceReferenceTransforms, FrameBone targetTransform, float chainRotationWeight)

Parameters

modelSpaceBoneTransforms Span<FrameBone>

modelSpaceReferenceTransforms ReadOnlySpan<FrameBone>

targetTransform FrameBone

chainRotationWeight float

Returns

bool
