osgRiver: 基于osgOcean的基于河流渲染的代码

基于osgOcean代码修改的基于河流渲染的代码。它有以下特点： 可以控制流向。 可以用颜色来反映河水的深度。 可以认为是迄今为止最好的河流模拟效果。

#include 

#include 

using namespace osgRiver;

/*

//
vector RiverSegment::CreateFromPoints（RiverFunction& riverFunction vector points RiverControlPoint curvePoint） {

	
}

//
vector RiverSegment::MergeRiverSegments（vector branch1 vector branch2 RiverControlPoint nextControlPoint） {

	vector total;

	RiverSegment* last1 = branch1[branch1.size（）-1];
	RiverSegment* last2 = branch2[branch2.size（）-1];

	RiverControlPoint lastControl1 = last1->getControlPoint3（）;
	RiverControlPoint lastControl2 = last2->getControlPoint3（）;

	RiverControlPoint lastControlAvg = （lastControl1 + lastControl2） * 0.5;

	RiverControlPoint nextControl1 = last1->getControlPoint3（） + （last1->getControlPoint3（） - last1->getControlPoint2（））;
	RiverControlPoint nextControl2 = last2->getControlPoint3（） + （last2->getControlPoint3（） - last2->getControlPoint2（））;

	RiverControlPoint nextControlAvg = （nextControl1 + nextControl2） * 0.5;

	RiverSegment* nextRiverSegment = new RiverSegment（last1->getRiverFunction（） lastControlAvg nextControlAvg nextControlPoint）;

	last1->addChild（nextRiverSegment）;
	last2->addChild（nextRiverSegment）;

	for （size_t i = 0; i < branch1.size（）; i++） {
		total.push_back（branch1[i]）;
	}

	for （size_t i = 0; i < branch2.size（）; i++） {
		total.push_back（branch2[i]）;
	}

	total.push_back（nextRiverSegment）;

	return total;
}
