MaxMSP/Jitter to MadMapper tutorial

Hi, in this tutorial, we will quickly learn how to send Jitter’s output to MadMapper.
To share video frames between application, we’ll use Syphon,
a framework developped by v002 team.
You can download a demo version of MadMapper at MadMapper’website

STEP#1
Download Syphon Max object.
You can get it from here Syphon Site
The direct download link is Syphon Jitter object
Once downloaded, make a new folder in your Max/patches folder, where you’ll copy the patches and helpfiles.
Here’s a view of my Max5 folder (normally located in /Applications)

STEP#2
Make a simple Jitter patch to playback a movie file.
Here, I’ve made a big bang button that triggers a metro object and a read message.
The read message uses the built-in countdown.mov quicktime video file.
All these are connected to a jit.qt.movie (sized at 320 by 240 pixels), whose output is connected
to a jit.pwindow (which is a in-patcher jitter window).
Normally, you should see the movie playing.
Note that you can send any Jitter matrix to Syphon, or and Jitter GLcontext, not just Quictime movies.

STEP#3
Send the movie to a Syphon server.
Now it is time to add all the objects necessary for Syphon to send the shared video frames to MadMapper.
So I’ve added:
- a jit.gl.syphonserver object, named JitterOutput, shown in red color.
- a jit.gl.videoplane object, to eventually visualize the shared context used by Syphon.
- a jit.window that will receive the Syphon context. It is currently invisible, but present in the patch.
- a jit.gl.render that will actually render the syphon context.
- a FPS counter, to check my framerate

STEP#4
Load MadMapper.
Syphon output coming from Jitter should be automatically displayed in the input media list,
under the Syphon section.
It is named ” JitterOuput” (as we did set it in STEP#3).
Now double click it in the list, and it should appear in the input view of MadMapper.
The size should be 320 by 240, as set in STEP#2.

STEP#5
Go to the Surface tab and make a Quad primitive.
Adjust its size and input cropping portion, using the blue handles.
The Quad should now appear in your Preview output on the right side of MadMapper.

STEP#6
Duplicate the selected Quad (Command-D) and make a few copies,
adjusting the size and position of each copies.

STEP#7
Now that your connexion is working, minimize MadMapper,
go back to Jitter and start experimenting.
Try with a Jitter matrix for instance, and fill it with random data.
