Functions

func Ease

func Ease(x float32, w float32) float32

@no-mutate / @:sampler / @:interpolation / @:functional Maps linear interpolation to a exponential function where x is in the [0,1] in [0,1 domain]. w is an exponential scale parameter for e^(-wq)

func Lerp

func Lerp(c float32, v0 float32, v1 float32) float32

Linearly Interpolates between two values

func SampleAverage1D

func SampleAverage1D(domain []float32, values []float32, n int, start_domain float32, end_domain float32, bindIndex *int) (float32, error)

Returns an average value under a sampling domain given value slices and their domain areas we assume the data provided is sorted. Out r domains sample endpoint in the domain. We can pass in the sample rs as slices

Types

type SampleData_1D

type SampleData_1D struct {
	Domain []float32 `json:"domain,omitempty"`
	Values []float32 `json:"values,omitempty"`
