osgModeling is a open source modeling library for OpenSceneGraph(OSG). Its purpose is to help generate kinds of parametric curves and surfaces, and calculate vertices, normals and texture coordnates automatically. For up-to-date information and latest versions of the project, please visit: http://code.google.com/p/osgmodeling/ For in-depth details of OpenSceneGraph, please visit its website: http://www.openscenegraph.org =============================== Requirements: =============================== - OpenSceneGraph: version 2.6.0 or higher =============================== Features: =============================== - Support for 4 kinds of curves: * k-degree Bezier curves. * k-degree NURBS curves. * Helix (3-dimensional spiral curves resembling a spring). * And user customized curves. - Support for 6 kinds of surfaces: * m,n-degree Bezier surfaces. * m,n-degree NURBS surfaces. * Extrusions (constructed by a profile extruded along a path). * Revolutions (constructed by a profile rotated specified angles). * Lofts (constructed by lofting a series of curves that define the cross section on a specified path). * And user customized models. - Generate normal arrays and texture coordinate arrays for various models (except user customizations). * Support 6 methods to generate normals with different weights. * Support the normal-flip operation. - Free to define customized algorithms to created vertices arrays, normal arrays and texture coordinate arrays for own models. - Construct the polygon mesh structures (Vertices-Edges-Faces) for geometries. - Subdivide polygon meshes into higher level using different methods. * Loop method: Split each face into 4 parts at every level to build subdivisions. * Sqrt(3) method: Split each face into 3 parts at every level to build subdivisions. - Construct the binary space partitioning (BSP) trees for models in built or converted from osg::Geometry. - Geometric boolean operations (Intersection, Union and Difference) based on BSP trees of models. =============================== How to build: =============================== The osgModeling uses the CMake build system to generate a platform-specific build environment. If you don't have CMake version 2.4.6 or later installed, you may download it from: http://www.cmake.org Under unices, type the following commands: ./configure make sudo make install Under Windows, just use the CMake GUI tool to build Visual Studio solutions. =============================== Libraries and examples: =============================== There are 1 or 2 dynamic library file after installation: - {libosgModeling.so | osgModeling.dll}: The library. - {libosgdb_osgmodeling.so | osgdb_osgmodeling.dll}: The reader/writer plugin. There are 5 executable files as examples: - osgmodelingbasic.exe: Demonstrates how to build extrusions, revolutions and lofts with osgModeling classes (Extrude, Lathe, Loft, Helix and so on). - osgmodelingboolean.exe: Demonstrates how to create a boolean object from two specified models. - osgmodelingbsptree.exe: Demonstrates how to build BSP trees for models. - osgmodelingnurbs.exe: Demonstrates how to create Bezier and NURBS surfaces with osgModeling classes. - osgmodelingsubd.exe: Demonstrates how to subdivide models using different levels and methods (Loop or Sqrt3). =============================== Bibliography: =============================== [1] Philip Schneider, David H.
