What is Lineair fanning and how to use?

erm what was wrong with this?? http://www.freestylersupport.com/fsforu ... p?f=5&t=11

sorry didn't kno that one only could remember there was this topic about it at the old forum, so searched that one. Your version probably is better :p

lol no worries m8

I clipped it out and saved it for future use—guess its the future.
Hope it helps

Linear Fanning - An Explanation

I've noticed a lot of people asking how fanning works.

Basically fanning allows you to give a regular offset to lights. This means than instead of all of your lights pointing straight out (I'll say you are using 5 lights), the middle one will be pointing straight out, the far left and far right ones will have the maximum off set, and the two between the centre and outside lights will be half way between straight out and maximum offset. The lights will have regular fan effect (like a fold out fan, the middle is straight up, the rest of the folds have a gradually increasing angle until the last one which has the maximum offset from the center.)

If you have managed to follow that (i don’t know how clear it will be), the option should make obvious sense to you. First = offset of the first light from center (if you have them addressed from left to right, First=Far left). Last = offset of the last light from center (Right). Center = offset of center light - if you want the entire fan pointing generally left/right you use this value.

Center Offset = defines where center is in the line of lights (0% defines far left as center, 100% defines far right as center so 50% is default. - remember, center in this case is the light (or point between lights) that is not affected by the fan, if the center is on a light, thn that light will point straight out and will not be affected by the fan.)

So its a bit complicated but very useful - especially for an interesting look on big rigs (try fanning multiple set of 4 or 5 lights). Hopefully this will help you all understand how this cool new feature works

Sorry, I don't understand that. I think my english is not good enough.
Is there someone who can explain it a bit easier?

[Crrispy]

I second this. My english is not too bad but it's difficult to understand. Maybe someone made a video that can explain/show the effects and use of this feature better than a few sentences?

Thanks.

Linear fanning gives a regular offset to lights, like when you fold out a paper fan - the lights point out to follow the lines in the fan - like this one: http://www.garden-gifts.com/images/redfan.jpg . If you applied a basic linaer fan to 3 lights they would face like below:

/ | \

On a little to the left, one in the centre, and one a little to the right. The slider for "First" adjusts how much of an offset the first light is given, so following on from the last example, if you increased the value on the "First" slider, your lights would point like below:

<- | \

The first one fully to the left, the other two as they were before. If you increased the slider marked "last", you would this:

<- | ->

the first light fully to the left, the centre one pointing straight out and the last one fully right.

Now if you left the settings the same, but applied them over 5 lights, you would get this:

<- / | \ ->

Can you see how they "fan" out from each other?
----------------------------------------------------------------------------------------------------------------------------------------------------------
Lets go back to saying we have 3 lights. The "centre" of the fan is the light which points straight out - the one which is not affected by the fan. In the last few examples, the 'centre offset' would have been set to 50% - making the centre of the fan, the middle light of the 3 lights - therefore it is pointing straight out. So if you were to set the centre offset to "0", you would make the far left light the 'centre' of the fan and you would get this:

| \ ->

The far left light is pointing straight out, the middle one is a bit to the right and the last one is fully right. If you set "centre offset" to 100% you would get this:

<- / |

Now the far right light is straight out. Basically you only have half of the "fan" because the centre of it is moved all the way left or right.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
DO NOT confuse "centre offset" with "centre". "Centre offset" moves the "centre" along the line of lights as described above. "centre" applies an angle to the centre light so it is not point straight out anymore - basically this allows you to apply a fan, then make the whole fan point the left or right. Imagine you are holding a paper fan and you rotate the whole thing to the left or right - the spacing between the lines in the fan has not changed, but the whole thing is pointing in a different direction, this is what the "centre" control does to the fan you have in your lights.

Hopefully this is an even MORE basic explanation that the old I posted on the old forums that seems to have made its way to the new ones... maybe the rough pictures even help....

OK thanks this makes things more clear! I suppose this is mostly used for moving heads?

Ok, now I understand how lineair fanning works. Many Thanks! I thing it woul be nice to have a wave generator in one of the next versions of Freestyler. So you can create a moving fan/wave.

[Mattotone]

fairly easy to create now.
Select your fixtures apply a vertical fan.
Set the movement to relative.
Scene 1. select fixtures in fan but select the lowest fanned position last and move all fixtures to top.
Scene 2. Do same but select the highest positioned fixture last and move to bottom.
Creates a nice fan effect.

Hmmm got my 4 moving heads yesterday, going to try this as soon as possible. I also want to create this "wave" effect with the 4 heads, it rocks!
But first have to make a fixture file and also in 3D easy viewer...
