Movement Effects on the Leap Frog

[rom]

Can somebody please explain me the functionality of the Offset and Rotation-effects on the LeapFrog :?:

 

I played around with these functions but was not able to figure out the exact function, or how I could use that

 

Even with RTFM I was not able to acquire furhter informations on that.

 

Thanks in advance,

rom.

Offset is one of the six parameters which defines a movement effect on the frog series of desks.

 

The Offset parameter determines how far through the movement, the effect starts when it is triggered or resynchronised.

 

Example: You have 4 scanners all doing the same movement effect (effect, size x, size y, offset, rotation and speed). If the offset has the same value for each scanner they will all do the same effect, starting at the same position.

 

By adjusting the offset parameter for each fixture using the fan-functions on the wheels, you can create a 'wave' effect or you can set the offset absolutely for each fixture using the control wheel.

 

Example: Set up four scanners with the same movement effect (effect = quad, size x as required, size y as required, rotation = 0, speed as required) Then for each of the four scanners set up the offset value individually as follows:

 

Scanner 1 offset = 0

Scanner 2 offset = 25%

Scanner 3 offset = 50%

Scanner 4 offset = 75%

 

Save the data to a memory, and then trigger the memory.

 

All four scanners will do the same effect but each will start at a different corner of the quad effect.

 

Rotation is another of the six movement effect parameters which simply rotates the shape by the specified number of degrees.

 

Example - Set up a simple 'vertical line' effect (effect = ellipse, X size = 0, Y size = as required, Speed = as required, Offset = 0). Adjust the Rotation parameter and you will see the line rotate.

Thank you K-Nine for your fast reply. I'll play around with this tonite!

With movement effects, it's often easier to try different parameter values and see what they look like .. it's not the easiest function to desribe clearly in words.

 

It's often easier to see what the diffferent effect parameters do if you have a number of fixtures of the same type all doing exactly the same effect initially. Then change one of the parameters, such as offset, giving each fixture a different value.

 

If you use the fan functions on the control wheels, remember that the function works across the selected fixtures in fixture number order, so it can be useful if your physical scanners or moving heads are arranged logically on the rig.
