第二次贴图为乱码

于英

采用一个图片对模型进行贴图，结果是正确的。程序不关，在对另外一个模型也采用图片进行贴图，显示的结果就是错的了。哪位大神清楚啊？



//创建二维纹理状态对象
osg::ref_ptr<osg::StateSet> createTexture2DState(std::string filename,int texture_unit)
{
        osgDB::Options  *a = NULL;
        osg::ref_ptr<osg::Image> image=osgDB::readRefImageFile((filename).c_str(),a);
        //创建状态集对象
        osg::ref_ptr<osg::StateSet> stateset = new osg::StateSet();
        //创建二维纹理对象
        osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D();
       
        texture->setDataVariance(osg::Object:YNAMIC);
        //设置贴图
        texture->setImage(image.get());
        texture->setTextureWidth(image->s());
        texture->setTextureHeight(image->t());
        stateset->setTextureAttributeAndModes(texture_unit,texture.get(),osg::StateAttribute::ON);
        osg::ref_ptr<osg::TexEnv> texenv=new osg::TexEnv;
        texenv->setMode(osg::TexEnv::REPLACE);               
        stateset->setTextureAttributeAndModes(texture_unit,texenv.get(),osg::StateAttribute::ON);
        osg::Texture::WrapMode textureWrapMode;
        textureWrapMode =osg::Texture::REPEAT;
        texture->setWrap(osg::Texture2D::WRAP_R, textureWrapMode);
        texture->setWrap(osg::Texture2D::WRAP_S, textureWrapMode);
        texture->setWrap(osg::Texture2D::WRAP_T, textureWrapMode);
        stateset->setTextureAttributeAndModes( texture_unit, texture,osg::StateAttribute::ON );
        return stateset.get();
}

//中函数中调用方法
               osg::ref_ptr<osg::Texture2D> texture1=new osg::Texture2D;
                theMesh1->setTexCoordArray(0,texcoords1.get());
                theMesh1->setStateSet(createTexture2DState(imagefilepath,0));
                geode1->setName(imagefilepath);
                geode1->addDrawable(theMesh1);

怎么每个人回复下呢？？？？
