Functions

LinearInterpolant.interpolate_(i1: any, t0: any, t: any, t1: any): TypedArray

Parameters:

• i1 any
• t0 any
• t any
• t1 any

Returns: TypedArray

Code

interpolate_( i1, t0, t, t1 ) {

        const result = this.resultBuffer,
            values = this.sampleValues,
            stride = this.valueSize,

            offset1 = i1 * stride,
            offset0 = offset1 - stride,

            weight1 = ( t - t0 ) / ( t1 - t0 ),
            weight0 = 1 - weight1;

        for ( let i = 0; i !== stride; ++ i ) {

            result[ i ] =
                    values[ offset0 + i ] * weight0 +
                    values[ offset1 + i ] * weight1;

        }

        return result;
