Hi my name is Peter.
And today on behalf of Pangolin Laser Systems, I'll be showing you how to use the new automatic
distributed scanning technology.
Distributed scanning is a great way to get more complex laser graphics at higher refresh
rates, through the use of more laser projectors automatically.
Rather than the more time-consuming method of manually dividing content over multiple
laser projectors.
Before distributed scanning, the entire image could be either split over projectors based
on the position.
So there would be always moments where one projector would be doing most of the work.
Or the animation would need to be manually drawn over multiple projectors, which made
more than two systems can be very confusing and rapidly time consuming.
Distributed scanning technology automatically determines the amount of points per laser
projector.
The minimum amount of points per projector is 500 points.
Over every increase of 500 the content will be passed on to the next laser projector until
there's no more projectors available.
Once there are no more projectors available the point count will be added up to all projectors.
To get started we need to make sure of the following things: One.
Projectors of equal brightness, color balance and beam quality.
If we do not have these things we'll see when other projectors take over the image.
You can learn more about setting your color balance by watching the video "Advanced color
palette settings in BEYOND".
Two.
You need to make sure your projectors are tuned to the ILDA test pattern.
Making sure that the blue circle is inside the green square.
We also need to make sure that the color shift is set correctly.
The color shift can be set correctly by looking at the space in between the dividing line.
It should be equal.
That way the color timings of every projectors is correct and we have no tails or disconnects.
The image needs to be equally overlapping and geometric correction needs to match.
If we don't do this, we'll get disconnections or deformed images.
Three.
You need FB4 hardware to do this.
A QM2000 or FB3 will not work.
Before starting with the demonstration, there are a few things to consider.
Since we were making use of mechanical devices to scan the image, we have a few things like
thermal drift and resolution limitations.
These shouldn't be a problem unless we're talking about very far distances.
In general the mechanical properties of laser projectors will smooth out resolution problems.
If this is an issue, a way to circumvent the thermal drift, is to run your laser projector
at zero percent brightness scanning images for a while.
Getting started.
In this demonstration I'll be showing you how to set up the laser projectors for distributed
scanning.
So what you want to do first is, go to your projector settings and shift-click to select
all.
Let's click back and forth.
Set all projectors from 50 by 50 to 100 by 100 to get the full angle of projection.
Now we want to go to our settings again, and go to our projection zones.
We click that, and so how I have it set up is, for every projector I have a zone.
One, two, three, four, five, six, going to each projector set separately, as you can
see.
So what I want to do is, I want to distribute all content that goes to the zone projector
one, to projector two, three, four, five and six.
So how I would do that is, first I have to set up the geometric correction to overlap
each other.
Because the content needs to be fitting inside of the same image.
So what I want to do is, bring up projector number one, and I will make a rough square
with this.
So let me just set that up.
Okay just make a rough zone here.
And that seems about right.
You can also use your mouse and the arrow keys to set this up.
John ward has a really good guide on this.
I will mention or I will put a link in the description, which you can follow along.
Because to save time on the video, I will be speeding up part of this setup.
So what I want to be doing is, bring up a grid.
The grid helps you to overlap the entire projection zone correctly.
So what i'm going to do is, make a match for each zone and make them overlap.
Also please spend your time on this, because it it's really needed.
It's a very precise alignment thing.
You can reduce the brightness if it helps you to align it.
Because it's going to get really bright.
I will fast forward the video to save time.
And once you've got it set up, where all projectors overlap, we can follow on to the next step.
Okay I'll call this done.
So now if you overlap all of them, you can see it's one really bright image.
So now what we want to do is, want to disable all these zones on this.
And we want to go to distribution.
So once we select distribution, we get an option of some projectors here.
These are only FB4 projectors that we can use.
So what we want to do is, we want to add all these projectors.
The order technically doesn't matter.
But it's what beyonds going to be using to distribute to an order.
So we click enable distributed scanning.
We should see two little arrows pointing.
And if you click ok now, and we project something complex or just something in general to our
projector number one, it will start distributing that content over multiple projectors.
I'll grab a better example.
I'll grab the city.
I'll set it to projected number one.
And now it will distribute this content over multiple projectors, automatically.
Make sure that the color shift of all your projectors is set equally.
So make sure that you go to your your size and position or scan rate.
And make sure that color shift is equal and even everything.
So make sure you open your ILDA test pattern and check the spacing between between those
lines.
Between the the lines I will point out in the video.
Those need to be evenly spaced in between.
If the timing is anywhere off then lines will start also disconnecting and things will just
look wrong.
So as you can see now the lines are nicely connecting.
Alright that will be it for this tutorial.
Thank you so much for watching.
And I hope you have a great day!
