Using translate in order for rotation to work properly Make a new color with an alpha component Int loc = (video.width – x – 1) + y*video.width // Reversing x to mirror the image Server = new SyphonServer(this, “Processing Syphon”) Start capturing the images from the camera Video = new Capture(this, width, height) This the default video input, see the GettingStartedCapture Number of columns and rows in our system * Each pixel from the video source is drawn as a rectangle with rotation based on brightness. It appeared the normal picture and the appearance of the picture was upside down in Arena.Ĭan you help me to solve it?Thank you so much ! I connected Arena and processing but the effect of mirror didn’t appear in Arnea. If I use processing example Video mirror with syphon

I hope that was all clear, feel free to comment below if you have an questions or comments.įull Processing source with tons of comments: Add the following to the end of your draw function and you’ll be set to move on to projecting.ĩ) Open up MadMapper now and you should be able to load in footage directy from your code, updated in realtime. The sketch will now show the drawing that is being done to the canvas.Ĩ) Finally we need to tell the server to serve the canvas to MadMapper. To fix this, add the following after canvas.endDraw(). That’s because we’re drawing to the canvas rather than the sketch itself.

Example code below:ħ) You’ll notice at this point that pressing play doesn’t show anything. Follow that with canvas.endDraw() to finish writing to the canvas. The normal drawing functions work from here now, but also must be prefixed with “canvas.” (for example canvas.line, canvas.ellipse). Before doing anything we must let Processing know we want to draw to the canvas rather than in the typical manner. We also construct the server here as well.Ħ) Now move on to the draw function. We also instantiate the canvas in a similar manner, with a matching resolution. In the setup function we declare the size of the screen with size, but add a third argument “P3D”, necessary for syphon to run correctly. We also create a variable “server” of type SyphonServer which is what ultimately serves the images to MadMapper. We have to do our drawing through this PGraphics instead of the typical method, but it really doesn’t change a whole lot in the end. Things to note, after importing the syphon library from step 4, we create a variable “canvas” of type PGraphics. Server = new SyphonServer(this, "Processing Syphon") Create syhpon server to send frames out. This should add an import command at the top of your source code.ĥ) Add the following both inside and outside your setup function to prepare to send the images: If it isn’t there, you messed up one of the previous steps :(. You should see an INSTALL.txt and a folder simply called Syphon.ģ) Drag the folder called Syphon into your libraries folder in your Processing folder, which is typically located at /Users/your_name/Documents/Processing/librariesĤ) Restart processing if it was running, and then go to Sketch>Import Library>Syphon.

Full Source code is at the bottom.ġ) Download Syphon for Processing through this link: Ģ) Extract the folder from the zip, and look inside.
Syphon allows the user to directly send the output of a Processing Sketch into MadMapper, or equivalent program.
