I know Processing provides box() and sphere() but I thought it would be nice to be able to create other 3D shapes such as a Helix, Cone, Tube etc. Not just that but provide support for textures (including tiling). The library supports both P3D and OPENGL but only uses commands available in Processing rather than using direct OpenGL access so should be compatible with future versions of Processing.

Anyway the library is simple to use, to find out more and see some examples head over to http://www.lagers.org.uk/s3d4p/index.html then click on the Examples link. Have a look at the Processing source code for Showcase and Earth & Moon to see how easy it is too use.

As and when I create new examples I will post links here.  

Enjoy

looks great and well done, love the examples.

Very nice.  Your GUI library looks great as well.

great examples! its great that it supports textures too.

When creating any of the shapes using the new command the first parameter is a reference to the PApplet object where it will be drawn. Since most shapes will be created inside the sketch main tab (or if using another IDE such as Eclipse the class that extends PApplet) then using 'this' is fine.

Lets say you want to create a class called Foo and in this class you want to create a Cone then

Code:

public class Foo{
  private PApplet app;
  private Cone cone;

  public Foo(PApplet papplet){
    app = papplet;
  }

  public void makeCone(){
    cone = new Cone(app, 20);
  }

}
 

In your main sketch you might have
Code:

void setup(){
  size(200,200,P3D);
  Foo foo = new Foo(this);
  foo.makeCone();
}
 

Later today I hope to release the next version of this library and the enhancements include 3D terrain and shape picking so watch out for the announcement in the Exhibition discourse.

Great, thanks for clearing that up Quark. And thanks for the library.

one other question:
if i had to make a class out of an object, eg. Cone, is there a way of adding it to another shape

void setup(){
 size(200,200,P3D);
 Foo foo = new Foo(this);
 foo.makeCone();
earth = new Ellipsoid(this, 20 ,30);
earth.addShape(foo);
}

Quark, on the earth example.  Just wondering if it would be possible to determine long and lat, and identify points on the texture.  So like add an identify for NYC.

I'd love to do something like this

Why not. If the coords are in degree, it should be quite easy to locate points a sphere. Take look at this formula: http://local.wasp.uwa.edu.au/~pbourke/geometry/prolatespheroid/.
Think lat as theta and long as phi.
