Android material L image transition interpolator
- by Diolor
This is more of a mathematics question rather than programming.
Well, I would like to ask id you know what is the interpolator described in Material design:
It looks to be an AccelerateDecelerateInterpolator but the deceleration effect decays slower.
My best hatch is :
public class MaterialInterpolator implements Interpolator {
@Override
public float getInterpolation(float input) {
if(input<1./3f)
return new AccelerateInterpolator().getInterpolation(input);
else
return new DecelerateInterpolator().getInterpolation(input);
}
}
Which creates a gap between the values:
Time / Value
0.3,0.09
0.317,0.100489
0.333,0.110889 <-- gap
0.35,0.57750005
0.367,0.599311
0.383,0.61931103
0.4,0.64
