Threading. From Processing This tutorial is based on my (somewhat outdated) Java tutorial about threads: The source code below from the examples below can be downloaded from here:
Threads at daniel shiffman. If you are looking for a tutorial about using threads in Processing, I’ve adapted this page on the Processing wiki: Examples: Related: Java Threads tutorial.
Inside the Hotspot VM: Clocks, Timers and Scheduling Events - Part I - Windows : David Holmes' Weblog. Clocks and Timers - General Overview There are two kinds of time related devices in a system: a means to read a time value; anda means to schedule/trigger a time related event The term "clock" is often used to refer to both of these because you read the time from a clock, and you can (often) set an alarm to have something happen when the clock reaches a certain time.
Sometimes the term "passive clock" is used for a time source that can only be read, while "active clock" is used for one that can also trigger an event/interrupt/alarm. For the sake of discussion (and because they are different hardware devices) I will use the term "clock" to refer to the means by which a time value can be read, and the term "timer" for something that can trigger a time-related event. Floating Processing clouds with minim. I made a simple example to test the sound input features of minim, an audio library for processing.
JSObject win = (JSObject)JSObject.getWindow(this); JSObject inputText = (JSObject) win.eval("document.forms.elements"); String value = (String)inputText.getMember("value"); // read form value inputText.setMember("value" , value + " new stuff"); // write form value But this action requires a signed applet. in Netscape, you must.
