Hello, I’ve developed a system for live visuals that involves rendering graphics in Processing, and I’m trying to add functionality to fade between two different displays: one that is currently being displayed on a projection, and a seocnd that is sort of a staging ground where I can preview visuals…

It’s not exactly clear to me what you are trying to do, but see if the following demo is somewhere close. The source code creates a PGraphics array which you can cycle through in the main default window. If you want one of those images to be shown in the Graphics window (PApplet) then you hit the …

Hi, thanks, this is helpful and is close to what I’m looking for. I actually think that the aspect that you’ve demonstrated is the part that I have figured out, which is getting a PGraphics instance to display on second window. The part I’ve been struggling with is drawing to a PGraphics instance th…

If it helps any further, this is an example of 3 windows where one fades between the other two (outside Processing IDE). [image] import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Rectangle; import processing.core.*; public class MultiSurface extends PApplet { …

I was wrong! I thought the drop in frame rate had to do with the fact that I was referencing the same PGraphics instance from two different PApplets, but it turns out I have the same problem even if I reference the same PGraphics instance twice within a single PApplet? Here’s something very similar…

Found a solution here: image() causes PImage reference to break when using PGraphics · Issue #5760 · processing/processing · GitHub A user there said: it looks like with the default Java2D renderer caching is not correctly cleared when calling endDraw() on an offscreen graphics, but only when dra…

Updating here for posterity’s sake. I did get everything set up in a multi-window setup by making calls to PGraphics.updatePixels(), but it seems like this is a pretty intensive function, so after a minute or two I start get pretty intense screen tearing: [output2] I don’t really know enough about…

[image] sdnorris: I’m guessing this has something to do with writing and reading to the buffer at the same time. This may be of interest: [image] Video Pixels Changing While I Process Them Libraries I’m using the Video 2.0 library with Processing 3.5.4 on Windows 10…
