interpolate method
Implementation
@override
interpolate(int i1, num t0, num t, num t1) {
var result = resultBuffer;
var values = sampleValues;
var stride = valueSize;
double v0 = t + (t0 * -1);
double v1 = t1 + (t0 * -1);
double alpha = v0 / v1;
var offset = i1 * stride;
for (var end = offset + stride; offset < end; offset += 4) {
Quaternion.slerpFlat(result, 0, values, offset - stride, values, offset, alpha);
}
return result;
}
