...make a half circle with my fixtures...

Recommended Posts

Interesting thing came to my mind recently...How do I program a half circle movement in the fixture section... I was first thinking about a 2 step chase with the circle effect but how do I exactly get the timing for my half circle and what is, when I have to adjust for example speed parameter or so live, because it's necessary for the show...Or is there maybe another solution except of the "chase" one....????

Hi Morn,

try when using "moving head´s " the ellipse effect is your friend,

give your fixtures a tilt value above 128-128 set effect size X to 50 and speed to 5 / 8 voilá your fixtures follow a half circle.

 

another solution is to use the triangle effect value with little more speed then the scans can´t reach all three points regulary...

 

Viel erfolg :D

Don't you just get a simple line, when you set one X/Y Parameter to Zero?

You would with a moving mirror fixture, but not necessarily with pan on a moving head. Like Haytech says, set the tilt value so the fixture is not pointing straight up. It depends on which way up your fixtures are rigged and which way they are pointing, but it can be done. It's all tied up with the same movement maths that makes a circle effect on a moving head come out as a figure of 8.

I'm using Technobeam Iris Moving Mirrors.... :?

As I remember the Technobeams have a Movement Speed function when programming a tri effect i.e. X=50 Y=25 Speed=8 MovSpeed=25

by playing around with these values you should get a half circle.

The mirror moves that slow, that it cant reach the 3points of the triangle.

maybe this works for you.
