 Returns the twist arc length distance between two quaternions, using a specific twist basis vector as reference.
Public function Static float

RBFKernel::Cubic ( float Value,
float Sigma
)

 A cubic falloff, with identical clamping behavior to the linear falloff, but with a smooth peak
Public function Static float

RBFKernel::Exponential ( float Value,
float Sigma
)

 An exponential falloff with a sharp peak
Public function Static float

RBFKernel::Gaussian ( float Value,
float Sigma
)

 A gaussian falloff
Public function Static float

RBFKernel::Linear ( float Value,
float Sigma
)

 A simple linear falloff, clamping at zero out when the norm of Value exceeds Sigma
Public function Static float

RBFKernel::Quintic ( float Value,
float Sigma
)

 A quintic falloff, with identical clamping behavior to the linear falloff, but with a flatter peak than cubic
