Ogre Procedural is an Ogre3D based library enabling developpers to quickly create geometric primitives, such as cubes, spheres, cylinders...

Source code and downloads you find on the project page.

Features

 
It can build the following primitives :

• Box, RoundedBox
• Plane
• Sphere, IcoSphere
• Cylinder, Tube, Capsule
• Cone
• Torus, Torus knot

 
More features:

• Extrusion
• Smooth lines by Bézier Curves (also usable for extrusion)
• SVG import (currently without Bézier import)
• OpenStreetMap data import
• Object description by XML file (as alternative to source code)

 
Planned:

• revolution based meshes
• a plug-in for the scene editor Ogitor

Download

 
Downloads are available in the download section of the project page.

Precompiled binaries are provided for VS2010 and for CB+MingW (linux support may come later, but I don't have a Mac...)
Source package is also available for all platforms (CMake based project files)

Usage Examples

 
Create a sphere:

//Initialisation
Procedural::Root::getInstance()->sceneManager = mSceneMgr;
//Create a sphere
Procedural::SphereGenerator().setRadius(5.f).setUTile(.5f).realizeMesh("mySphere");
mSceneMgr->createEntity("mySphere");

 
Create a pipeline:

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");

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):

Load the shape and define a path:

Extrude:

// 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);

How to build

 
This is a list of basic steps to compile ogre-procedural from source.
Prerequisites:

• Install Cmake
• Install Ogre, either from source or precompiled SDK (1.7 or 1.8)
• If you are using MS Windows, make sure that there's an evironnement variable OGRE_HOME set to your ogre SDK directory

 
Compiling and running the sample:

• Generate project files using Cmake
• Compile, run, and enjoy ...
