<p>
|
||||
The DXF library writes all triangle-based graphics (polygons, boxes, spheres, etc.) to a DXF file.
|
||||
It works with the <strong>beginRaw()</strong> and <strong>endRaw()</strong> functions.
|
||||
These functions will grab and save the shape data just before it is rendered to the screen.
|
||||
At this stage, your entire scene is nothing but a long list of lines and triangles.
|
||||
This means that a shape created with the <strong>sphere()</strong> function will be made up of
|
||||
hundreds of triangles, rather than a single object. The source code is available on the <a href="https://github.com/processing/processing/tree/master/java/libraries/dxf">Processing</a> GitHub repository. Please report bugs <a href="https://github.com/processing/processing/issues">here</a>.
|
||||
</p>
|
||||
<p>
|
||||
Use an event function like a <strong>keyPressed()</strong> to trigger it, to avoid writing a
|
||||
file each time through <strong>draw()</strong>. By default, the file will be saved to the
|
||||
sketch's folder. Use Sketch > Show Sketch Folder to see it from the Processing Environment.
|
||||
</p>
|
||||
|
||||
<p>This simple example shows how to use the library: </p>
|
||||
|
||||
<pre>import processing.dxf.*;
|
||||
|
||||
boolean record;
|
||||
|
||||
void setup() {
|
||||
size(500, 500, P3D);
|
||||
}
|
||||
|
||||
void draw() {
|
||||
if (record) {
|
||||
beginRaw(DXF, "output.dxf");
|
||||
}
|
||||
|
||||
// Do all your drawing here
|
||||
if (record) {
|
||||
endRaw();
|
||||
record = false;
|
||||
}
|
||||
}
|
||||
|
||||
void keyPressed() {
|
||||
// Use a key press so that it doesn't make a million files
|
||||
if (key == 'r') {
|
||||
record = true;
|
||||
}
|
||||
}

Calls a function when the value of an input pin changes<br/>

<br/>
|

The sketch method provided must accept a single integer (int) parameter, which is the
|
||||
number of the GPIO pin that the interrupt occured on. As this method might be called
|
||||
at any time, including when drawing to the display window isn't permitted, it is best
|
||||
to only set simple variables that are being responded to in the next draw() call, as
|
||||
shown above. Calling functions of the Hardware I/O library at this point is certainly
|
||||
possible.<br/>
|
||||
<br/>
|
||||
The mode parameter determines when the function will be called: GPIO.FALLING occurs when the level changes from high to low, GPIO.RISING when the level changes from low
|
||||
to high, and GPIO.CHANGE when either occurs.

Opens an I2C interface as master<br/>
|
||||
<br/>
|
||||
I2C is a serial bus, commonly used to attach peripheral ICs (Integrated Circuits)
|
||||
to processors and microcontrollers. It uses two pins, SDA (for data) and SDL (for
|
||||
the clock signal). Multiple "slave" devices can be connected to the same bus, as
|
||||
long as they are responding to different addresses (see below).<br/>
|
||||
<br/>
|
||||
The I2C "master" device initiates a transmission, which includes sending the
|
||||
address of the desired "slave" device. I2C addresses consist of 7 bits plus one
|
||||
bit that indicates whether the device is being read from or written to. Some
|
||||
datasheets list the address in an 8 bit form (7 address bits + R/W bit), while
|
||||
others provide the address in a 7 bit form, with the address in the lower 7 bits.<br/>
|
||||
<br/>
|
||||
This library expects addresses in their 7 bit form, similar to Arduino's Wire
|
||||
library, and what is being output by the i2cdetect utility on Linux. If the
|
||||
address provided in a datasheet is greater than 127 (hex 0x7f) or there are
|
||||
separate addresses for read and write operations listed, which vary exactly by
|
||||
one, then you want to shift the this number by one bit to the right before passing
|
||||
it as an argument to <a href="I2C_beginTransmission_.html">beginTransmission()</a>.

Opens an SPI interface as master<br/>
|
||||
</br>
|
||||
Serial Peripheral Interface (SPI) is a serial bus, commonly used to communicate
|
||||
with sensors and memory devices. It uses four pins: MOSI (Master Out Slave In),
|
||||
MISO (Master In Slave Out), and SCLK (clock signal) - those three are shared
|
||||
among all devices on the bus - as well as one or more SS (Slave Select) pins,
|
||||
that are used for the master to signal to the slave device that it is the
|
||||
desired respondent for the transmission.<br/>
|
||||
<br/>
|
||||
The "master" device initiates a transfer by pulling the SS pin of the "slave"
|
||||
low, and begins outputting a clock signal. In SPI, both the "master" as well as
|
||||
the "slave" device output data at the same time. It is hence not possible to
|
||||
read data without writing some (even if it means outputting zeros or other
|
||||
dummy data).</br>
|
||||
</br>
|
||||
There are multiple possible configuration settings for SPI, see
|
||||
<a href="SPI_settings_.html">settings()</a> for details.</br>
|
||||
<br/>
|
||||
This library supports multiple SPI objects making use of the same SPI
|
||||
interface.

Opens an RC servo motor connected to a GPIO pin<br/>
|

</br>
|

This library uses timers to control RC servo motors by means of pulse width
|
||||
modulation (PWM). While not as accurate as dedicated PWM hardware, it has
|
||||
shown to be sufficient for many applications.<br/>
|
||||
<br/>
|
||||
Connect the signal wire (typically colored yellow) to any available GPIO pin
|
||||
and control the servo's angle as shown in the example sketch.

The Hardware I/O library allows access to the computer's hardware periperals, such as digital
|
||||
inputs and outputs, serial busses, and the like, in a fashion similar to the Arduino plaform.
|

This library is only available for embedded Linux boards with the necessary kernel drivers,
|
||||
such as the Raspberry Pi.

Reads from the port into a buffer of bytes up to and including a particular character. If the character isn't in the buffer, 'null' is returned. The version with no <b>byteBuffer</b> parameter returns a byte array of all data up to and including the <b>interesting</b> byte. This is not efficient, but is easy to use. The version with the <b>byteBuffer</b> parameter is more memory and time efficient. It grabs the data in the buffer and puts it into the byte array passed in and returns an int value for the number of bytes read. If the byte buffer is not large enough, -1 is returned and an error is printed to the message area. If nothing is in the buffer, 0 is returned.

A server sends and receives data to and from its associated clients (other programs connected to it). When a server is started, it begins listening for connections on the port specified by the <b>port</b> parameter. Computers have many ports for transferring data and some are commonly used so be sure to not select one of these. For example, web servers usually use port 80 and POP mail uses port 110.

Note that the address may be part of a <a href="http://en.wikipedia.org/wiki/Private_network">private network</a> and only accessible to other machines within the same network. In other cases, a publicly accessible address may be returned (though additional router configuration work may be needed to route connections to your machine). In either case, it depends on how the network you connect to is configured and (more rarely) on the network settings of your machine.

<p>The PDF library makes it possible to write PDF files directly from Processing. These vector graphics files can be scaled to any size and output at very high resolutions. The PDF library can flatten 3D data into a 2D vector file, but to export 3D data, use the DXF library. The source code is available on the <a href="https://github.com/processing/processing/tree/master/java/libraries/pdf">Processing</a> GitHub repository. Please report bugs <a href="https://github.com/processing/processing/issues">here</a>.<br />
|
||||
<br />
|
||||
This library is frequently used with the core Processing function <strong>size()</strong>, with a combination of <strong>beginRecord()</strong> and <strong>endRecord()</strong>, or with <strong>beginRaw()</strong> and <strong>endRaw()</strong>. The <strong>createGraphics()</strong> function can also be useful. See the examples below for different techniques.</p>

<strong>Single Frame (No Screen Display)</strong><br />
|
||||
<br />
|
||||
This example draws a single frame to a PDF file and quits. (Note that no display window will open; this helps when you're trying to create massive PDF images that are far larger than the screen size.)</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
void setup() {
|
||||
size(400, 400, PDF, "filename.pdf");
|
||||
}
|
||||
|
||||
void draw() {
|
||||
// Draw something good here
|
||||
line(0, 0, width/2, height);
|
||||
|
||||
// Exit the program
|
||||
println("Finished.");
|
||||
exit();
|
||||
}</pre>
|
||||
|
||||
|
||||
<p><strong>Multiple Pages (No Screen Display)</strong><br />
|
||||
<br />
|
||||
It's possible to write every frame as a new page in the PDF document.
|
||||
This example creates a 100 page document:</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
void setup() {
|
||||
size(400, 400, PDF, "filename.pdf");
|
||||
}
|
||||
|
||||
void draw() {
|
||||
// Draw something good here
|
||||
line(0, 0, frameCount * 4, height);
|
||||
|
||||
PGraphicsPDF pdf = (PGraphicsPDF) g; // Get the renderer
|
||||
|
||||
// When finished drawing, quit and save the file
|
||||
if (frameCount == 100) {
|
||||
exit();
|
||||
} else {
|
||||
pdf.nextPage(); // Tell it to go to the next page
|
||||
}
|
||||
}</pre>
|
||||
|
||||
|
||||
<p><strong>Single Frame (With Screen Display)</strong><br />
|
||||
<br />
|
||||
To draw to the screen while also saving a PDF, use the beginRecord()
|
||||
and endRecord() functions. This is slower, but is useful when you need to
|
||||
see what you're working on as it saves.</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
void setup() {
|
||||
size(400, 400);
|
||||
noLoop();
|
||||
beginRecord(PDF, "filename.pdf");
|
||||
}
|
||||
|
||||
void draw() {
|
||||
// Draw something good here
|
||||
line(0, 0, width/2, height);
|
||||
|
||||
endRecord();
|
||||
}</pre>
|
||||
|
||||
|
||||
<p><strong>Single Frame from an Animation (With Screen Display)</strong><br />
|
||||
It's also possible to save one frame from a program with moving elements.
|
||||
Create a boolean variable to turn the PDF recording process on and off</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
boolean record;
|
||||
|
||||
void setup() {
|
||||
size(400, 400);
|
||||
}
|
||||
|
||||
void draw() {
|
||||
if (record) {
|
||||
// Note that #### will be replaced with the frame number. Fancy!
|
||||
beginRecord(PDF, "frame-####.pdf");
|
||||
}
|
||||
|
||||
// Draw something good here
|
||||
background(255);
|
||||
line(mouseX, mouseY, width/2, height/2);
|
||||
|
||||
if (record) {
|
||||
endRecord();
|
||||
record = false;
|
||||
}
|
||||
}
|
||||
|
||||
// Use a keypress so thousands of files aren't created
|
||||
void mousePressed() {
|
||||
record = true;
|
||||
}</pre>
|
||||
|
||||
|
||||
<p><strong>Many Frames Into One File (With Screen Display)</strong><br />
|
||||
<br />
|
||||
The following example records absolutely everything that happens
|
||||
while a sketch is running. Hitting the 'q' key will quit the sketch.
|
||||
The sketch calls exit(), which is necessary to make sure that the file
|
||||
is properly written when complete.</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
void setup() {
|
||||
size(400, 400);
|
||||
beginRecord(PDF, "everything.pdf");
|
||||
}
|
||||
|
||||
void draw() {
|
||||
// Be sure not to call background, otherwise your file
|
||||
// will just accumulate lots of mess, only to become invisible
|
||||
|
||||
// Draw something good here
|
||||
line(mouseX, mouseY, width/2, height/2);
|
||||
}
|
||||
|
||||
void keyPressed() {
|
||||
if (key == 'q') {
|
||||
endRecord();
|
||||
exit();
|
||||
}
|
||||
}</pre>
|
||||
|
||||
|
||||
<p><strong>Pausing While Recording (With Screen Display)</strong><br />
|
||||
<br />
|
||||
It's also possible to pause/resume recording along the way.
|
||||
The following example toggles recording on/off each time you hit the 'r' key.
|
||||
Pressing the 'q' key will quit the sketch.</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
boolean recording;
|
||||
PGraphicsPDF pdf;
|
||||
|
||||
void setup() {
|
||||
size(400, 400);
|
||||
pdf = (PGraphicsPDF) createGraphics(width, height, PDF, "pause-resume.pdf");
|
||||
}
|
||||
|
||||
void draw() {
|
||||
// Be sure not to call background, otherwise your file
|
||||
// will just accumulate lots of mess, only to become invisible
|
||||
|
||||
// Draw something good here
|
||||
if (mousePressed) {
|
||||
line(pmouseX, pmouseY, mouseX, mouseY);
|
||||
}
|
||||
}
|
||||
|
||||
void keyPressed() {
|
||||
if (key == 'r') {
|
||||
if (recording) {
|
||||
endRecord();
|
||||
println("Recording stopped.");
|
||||
recording = false;
|
||||
} else {
|
||||
beginRecord(pdf);
|
||||
println("Recording started.");
|
||||
recording = true;
|
||||
}
|
||||
} else if (key == 'q') {
|
||||
if (recording) {
|
||||
endRecord();
|
||||
}
|
||||
exit();
|
||||
}
|
||||
}
|
||||
</pre>
|
||||
|
||||
|
||||
<p><strong>PDF Files from 3D Geometry (With Screen Display)</strong><br />
|
||||
<br />
|
||||
To create vectors from 3D data, use the beginRaw() and endRaw() commands.
|
||||
These commands will grab the shape data just before it is rendered to the screen.
|
||||
At this stage, your entire scene is nothing but a long list of lines and triangles.
|
||||
This means that a shape created with sphere() method will be made up of hundreds of
|
||||
triangles, rather than a single object.</p>
|
||||
|
||||
<p>When using beginRaw() and endRaw(), it's possible to write to either a 2D or 3D renderer.
|
||||
For instance, beginRaw() with the PDF library will write the geometry as flattened triangles
|
||||
and lines.</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
boolean record;
|
||||
|
||||
void setup() {
|
||||
size(500, 500, P3D);
|
||||
}
|
||||
|
||||
void draw() {
|
||||
if (record) {
|
||||
beginRaw(PDF, "output.pdf");
|
||||
}
|
||||
|
||||
// Do all your drawing here
|
||||
background(204);
|
||||
translate(width/2, height/2, -200);
|
||||
rotateZ(0.2);
|
||||
rotateY(mouseX/500.0);
|
||||
box(200);
|
||||
|
||||
if (record) {
|
||||
endRaw();
|
||||
record = false;
|
||||
}
|
||||
}
|
||||
|
||||
// Hit 'r' to record a single frame
|
||||
void keyPressed() {
|
||||
if (key == 'r') {
|
||||
record = true;
|
||||
}
|
||||
}
|
||||
</pre>
|
||||
|
||||
<p><strong>Using createGraphics() to Create a PDF File</strong><br />
|
||||
<br />
|
||||
To write a PDF file using only the createGraphics() command, rather than as
|
||||
part of a sketch, it's necessary to call dispose() on the PGraphicsPDF object.
|
||||
This is the same as calling exit(), but it won't quit the sketch.</p>
|
||||
|
||||
<pre>import processing.pdf.*;
|
||||
|
||||
PGraphics pdf = createGraphics(300, 300, PDF, "output.pdf");
|
||||
pdf.beginDraw();
|
||||
pdf.background(128, 0, 0);
|
||||
pdf.line(50, 50, 250, 250);
|
||||
pdf.dispose();
|
||||
pdf.endDraw();</pre>
|
||||
|
||||
|
||||
<p>
|
||||
<strong>Additional notes for the PDF renderer:</strong>
|
||||
|
||||
<ul>
|
||||
|
||||
<li>If you want 3D data, use the DXF recording library instead.
|
||||
|
||||
<li>Using hint(ENABLE_DEPTH_SORT) can improve the appearance of 3D geometry drawn to 2D file formats.
|
||||
|
||||
<li>Images don't look great, mostly because of the difference of
|
||||
expectations in how a PDF should look (scalable and high res) versus
|
||||
what happens when image data is written to it at 72 dpi.
|
||||
|
||||
<li>Starting in release 0120, text is no longer treated as shape data by
|
||||
default, meaning that the font will need to be installed to view the
|
||||
PDF that's created. The upside is that the PDF will render better. To force text
|
||||
to be treated as shape data, use textMode(SHAPE), immediately after size().
|
||||
<!--See the developer reference for textMode() inside
|
||||
<A HREF="http://dev.processing.org/reference/everything/javadoc/processing/pdf/PGraphicsPDF.html">
|
||||
PGraphicsPDF</A> for more specifics.-->
|
||||
|
||||
<li>Another option for type, is to use createFont() with a TrueType font
|
||||
(some OpenType fonts also work). Any font that shows up in PFont.list()
|
||||
should work, or if not, adding a .ttf file to the data directory and
|
||||
calling createFont("fontname.ttf") will also work.
|
||||
|
||||
<li>If loadFont() is used instead of createFont(), the text may show up
|
||||
bitmapped and ugly. In some cases, hint(ENABLE_NATIVE_FONTS)
|
||||
may improve the situation if the font is installed on the machine.
|
||||
|
||||
<!-- Removed by REAS, 1 September 2011, couldn't find reference in the current Issue database-->
|
||||
<!--<li>On Mac OS X, the seems to be a bug in Apple's Java implementation
|
||||
that confuses cubic vs. quadric splines. This makes text look jagged,
|
||||
even though it's not bitmapped.
|
||||
(<A HREF="http://dev.processing.org/bugs/show_bug.cgi?id=404">Bug 404</A>)-->
|
||||
|
||||
<!-- Removed by REAS, 1 September 2011, couldn't find reference in the current Issue database-->
|
||||
<!--<li>If the results with beginRaw() from P3D to PDF look bizarre,
|
||||
it's probably because the polygons are not sorted.
|
||||
To attempt sorting of 3D shapes before they're written to a file,
|
||||
use hint(ENABLE_DEPTH_SORT). This method is still
|
||||
not particularly good, but will help in some situations.
|
||||
See <a href="http://dev.processing.org/bugs/show_bug.cgi?id=176">Bug
|
||||
176</a> for status of the implementation.</p>-->
|
||||
|
||||
<li>Starting a new page is a matter of calling nextPage() like so:
|
||||
<pre>
|
||||
PGraphicsPDF pdf = (PGraphicsPDF) g;
|
||||
pdf.nextPage();
|
||||
</pre>
|
||||
(This example is also shown above)
|
||||
|
||||
<li> Again, exit() is really important when using PDF with size().
|
||||
|
||||

|

The Serial library reads and writes data to and from external devices one byte at a time. It allows two computers to send and receive data. This library has the flexibility to communicate with custom microcontroller devices and to use them as the input or output to Processing programs. The serial port is a nine pin I/O port that exists on many PCs and can be emulated through USB.
|
||||
</p>
|
||||
<p>
|
||||
Issues related to the Serial library on different platforms are documented on the <a href="https://github.com/processing/processing/wiki/Serial-Issues">Processing Wiki</a>. The source code is available on the <a href="https://github.com/processing/processing/tree/master/java/libraries/serial">processing</a> GitHub repository.
|
||||
</p>
|
||||
<p>
|
||||
When sending data to the console, such as via print() or println(), note that the console is relatively slow. It does not support high-speed, real-time output (such as at 60 frames per second). For real-time monitoring of serial values, render those values to the Processing window during draw().
