|
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>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;
|
|
}
|
|
}
|
|
</pre>
