cha_twirl.yafa

Lets use the cool twirl effect.

(do not forget the output name!)

{wftut:halve_size/results/cha_twirl.yafa}

Variable:      rotate
Points:         5
Nr. 1:          0,    0   ... Start 0°
Nr. 2:         20,  100 
Nr. 2:         30,  210
Nr. 2:         40,  100
Nr. 2:         60,    0   ... End 0°
Interpolation: spline

We add the twirl effect in the processor:

{ADD TWIRL}

We choose the following settings:

{INPUT Stream}       ... Input Pictures
{OUTPUT Stream}      ... Output animation
{FALLOFF out}        ... Direction of more power
{CENTREX 88}  [176]  ... centre of the pictures
{CENTREY 72}  [144]
{RADIUS 150}  [220]  ... twirl-radius
{AMOUNT rotate}      ... degrees
{POWER 1}            ... Power stays the same
{ZOOM 1}             ... zoom-amount

The twirl effect is very time-consuming. Start the converting and if you
have a slow amiga just drink a can of coffee :-)

After this interesting effect we go on with  Part 5 .
