示例1: write

	bool BoneAnimationSet::write(string filename,float fCopress)
	{
		//filename = m_strName+"1";
		Stream *pDataStream;
		DataChunk writeChunk;

		//最新版本是7,把所有旧的版本转换为版本4
		//写 'MVER'
		writeChunk.beginChunk('MVER', &pDataStream);
		uint ver = 4 ;//在导出插件里面计算aabb
		pDataStream->write(&ver,sizeof(ver));
		writeChunk.endChunk();

		//写 'MANM'
		uint32 nAnims = m_vAnimations.size();
		//add by yhc 2010.5.10
		//修正前一个动作的结束时间和后一个动作的开始时间一样的饿问题
		bool bFixWrongTime = false;
		if( nAnims > 0)
		{
			if( nAnims>1 && m_vAnimations[0]->getTimeEnd()==m_vAnimations[1]->getTimeStart() )
				bFixWrongTime = true;

			writeChunk.beginChunk('MANM', &pDataStream);
			pDataStream->write( &nAnims, sizeof(nAnims) );
			for( uint i =0; i < nAnims; i++)
			{
				string animname = m_vAnimations[i]->getName();
				uchar animnameLen = animname.size();
				pDataStream->write(&animnameLen, sizeof( animnameLen) );
				pDataStream->write(animname.c_str(), animnameLen);
				uint startTime,endTime;
				startTime = m_vAnimations[i]->getTimeStart();
				if(bFixWrongTime)
					startTime += i*33;

				endTime = m_vAnimations[i]->getTimeEnd();
				if(bFixWrongTime)
					endTime += i*33;
				pDataStream->write(&startTime, sizeof(startTime));
				pDataStream->write(&endTime, sizeof(endTime));
			}
			writeChunk.endChunk();
		}

		//写 'MBON'
		uint nBones = m_vBones.size();
		if( nBones > 0)
		{
			writeChunk.beginChunk('MBON', &pDataStream);
			pDataStream->write( &nBones, sizeof(nBones) );
			for( uint i = 0; i < nBones; i++)
			{
				int id  = m_vBones[i]->objectId;
				pDataStream->write( &id, sizeof(id));
				string Jointname = m_vBones[i]->name;
				uchar JointnameLen = Jointname.size();
				pDataStream->write( &JointnameLen, sizeof(JointnameLen) );
				pDataStream->write( Jointname.c_str(), JointnameLen);
				int parent = m_vBones[i]->parentId;
				pDataStream->write( &parent, sizeof(parent) );
				Vector3 pivot = m_vBones[i]->pivotPoint;
				pDataStream->write( &pivot, sizeof(pivot) );

				//写骨骼的初始变换矩阵
				pDataStream->write(m_vBones[i]->initTrans.val,sizeof(float)*3);
				float _r[4];
				_r[0] = m_vBones[i]->initQuat.x;
				_r[1] = m_vBones[i]->initQuat.y;
				_r[2] = m_vBones[i]->initQuat.z;
				_r[3] = m_vBones[i]->initQuat.w;
				pDataStream->write(_r, sizeof(float)*4);
				pDataStream->write(m_vBones[i]->initScale.val, sizeof(float)*3);

				KeyFrames<Vector3> translation;
				KeyFrames<Quaternion> rotation;
				KeyFrames<Vector3> scale;
				
				//去掉重复和多余的keyframe 
				CompressPos(m_vBones[i]->translation,translation,fCopress);
				uint nKeyFrames = translation.numKeyFrames();
				//修正时间
				if(bFixWrongTime)
				{
					int nCurAniIndex=0;
					for( uint ii = 0; ii < nKeyFrames; ii++)
					{
						KeyFrame<Vector3> * kf =  translation.getKeyFrame(ii);
						if( kf->time>m_vAnimations[nCurAniIndex]->getTimeEnd() )
							nCurAniIndex++;
						kf->time += nCurAniIndex*33;
					}

				}
				pDataStream->write( &nKeyFrames, sizeof(nKeyFrames) );
				for( uint ii = 0; ii < nKeyFrames; ii++)
				{
					ModelKeyframeTranslation mkft;
					mkft.time = translation.getKeyFrame(ii)->time;
					mkft.v[0] = translation.getKeyFrame(ii)->v[0];
