Functions

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

Parameters:

• i1 any
• t0 any
• t any
• t1 any

Returns: TypedArray

Calls:

• Quaternion.slerpFlat

Code

interpolate_( i1, t0, t, t1 ) {

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

            alpha = ( t - t0 ) / ( t1 - t0 );

        let offset = i1 * stride;

        for ( let end = offset + stride; offset !== end; offset += 4 ) {

            Quaternion.slerpFlat( result, 0, values, offset - stride, values, offset, alpha );

        }
