osgUtil.PolytopeIntersector

OpenSceneGraph提供了osgUtil.PolytopeIntersector类用于计算相交的多面体。

概述

osgUtil.PolytopeIntersector是一个与OpenSceneGraph场景图交互的工具。该类的目的是找到一个多面体(由视图传递)与场景图中的几何体(多边形、三角形、线、点等)的交集。

使用方法

osgUtil.PolytopeIntersector的使用需要以下步骤:

  1. 定义一个osgUtil.PolytopeIntersector对象。
  2. 定义视点、视线、投影矩阵和视口大小等信息。
  3. 使用osgUtil.IntersectorVisitor访问场景图中的节点。
  4. 在访问节点时,将PolytopeIntersector对象传递给节点。

代码示例

以下是一个简单的代码示例:

#include <osgViewer/Viewer>
#include <osgUtil/PolytopeIntersector>

int main()
{
    // 定义视图信息
    osg::Vec3 eye(0,0,5), center(0,0,0), up(0,1,0);
    osg::Vec4 viewport(0,0,800,600);
    osg::Matrix projection = osg::Matrix::perspective(30.0f, viewport[2]/viewport[3], 1.0f, 1000.0f);
    osg::Matrix view = osg::Matrix::lookAt(eye, center, up);

    // 定义多面体
    osg::Polytope polytope;
    polytope.setToUnitFrustum( true, true );

    // 定义intersectVisitor
    osg::ref_ptr<osgUtil::PolytopeIntersector> intersector = new osgUtil::PolytopeIntersector(polytope);
    osgUtil::IntersectionVisitor iv(intersector.get());
    iv.setProjectionMatrix(projection);
    iv.setViewMatrix(view);
    iv.setViewport(viewport);

    // 加载模型文件
    osg::ref_ptr<osg::Node> model = osgDB::readNodeFile("cow.osg");

    // 访问模型
    model->accept(iv);

    // 获取相交信息
    if (intersector->containsIntersections())
    {
        osgUtil::PolytopeIntersector::Intersections& results = intersector->getIntersections();
        for (osgUtil::PolytopeIntersector::Intersections::iterator itr = results.begin(); itr != results.end(); ++itr)
        {
            osgUtil::PolytopeIntersector::Intersection intersection = *itr;
            osg::NodePath nodePath = intersection.nodePath;
            osg::Vec3f localIntersectionPoint = intersection.getLocalIntersectionPoint();
            osg::Vec3f worldIntersectionPoint = intersection.getWorldIntersectPoint();
            osg::Geode* geode = nodePath.back()->asGeode();
            if (geode)
            {
                osg::Drawable* drawable = geode->getDrawable(0);
                if (drawable)
                {
                    // 处理相交信息
                }
            }
        }
    }

    // 创建场景图节点
    osg::ref_ptr<osg::Group> root = new osg::Group;
    root->addChild(model);

    // 创建viewer
    osgViewer::Viewer viewer;
    viewer.setSceneData(root);
    return viewer.run();
}
