!!Features

Existing features in current release (0.2):
* Primitives : Box, RoundedBox, Plane, Sphere, IcoSphere, Cylinder, Tube, Capsule, Cone, Torus and Torus knot
* Extrusion
* Lathe
* Triangulation
* Smooth splines by [http://en.wikipedia.org/wiki/B%C3%A9zier_curve|Bézier Curves] (also usable for extrusion)
* Constructive solid geometry in 2D

Planned / not yet in the official release:
* A plug-in for the scene editor ((Ogitor))
* SVG import (currently without Bézier import)
* OpenStreetMap data import
* Object description by XML file (as alternative to source code)

!!Download

Downloads are available in the [http://code.google.com/p/ogre-procedural/downloads/list|download section] of the project page.

Precompiled binaries are provided for Visual Studio 9,10,11 and for MingW : [http://code.google.com/p/ogre-procedural/downloads/list|here] for the stable release, and [http://files.ogreci.org/OgreProcedural/|there] for nightly builds.
Source package is also available for all platforms (CMake based project files)

!!Usage Examples

__Create a sphere:__
{CODE(wrap="1", colors="c++")}
#include "Procedural.h"
Procedural::SphereGenerator().setRadius(5.f).setUTile(.5f).realizeMesh("mySphere");
mSceneMgr->createEntity("mySphere");
{CODE}

__Create a pipeline:__
{CODE(wrap="1", colors="c++")}Procedural::Path p = Procedural::BezierPath().addPoint(0,5,0).addPoint(0,4,10).addPoint(10,5,10).close().realizePath();
Procedural::Shape s = Procedural::CircleShape().setRadius(1.5).realizeShape();
Procedural::Extruder().setExtrusionPath(&p).setShapeToExtrude(&s).realizeMesh("extrudedMesh");{CODE}

!!Advanced example

This example shows how to create a shape by a vector graphic application and how to use it for extruding.

Create SVG shape (e.g. with Inkscape):
{img fileId="2059"}

Load the shape and define a path:
{img fileId="2058"}

Extrude: 
{img fileId="2060"}

{CODE(wrap="1", colors="c++")}
// load inkscape .svg file into a shape:
Shape shape = Shape();
shape.loadFromSVG("inkscape-test.svg", "path2985");

// construct the spline we want to extrude along:
CatmullRomSpline3 pp;
pp.addPoint(0,-5,0).addPoint(50,-5,250).addPoint(500,-5,500).setNumSeg(10);
Path line = pp.realizePath();

// extruder and mesh generation
putMesh(shape.realizeMesh());
putMesh(line.realizeMesh(),1);
Extruder e;
putMesh(e.setShapeToExtrude(&shape).setExtrusionPath(&line).realizeMesh(),1);
{CODE}
