我的是pcl+qt成功编译了qvtkwidget我最近在编写颜色条代码如下：pcl::PointCloud<pcl::PointXYZRGBNormal>pointcloud = curr_pointcloud;pcl::PointXYZRGBNormal p_min;pcl::PointXYZRGBNormal p_max;pcl::getMinMax3D(pointcloud, p_min, p_max);double distance = abs(p_min.z - p_max.z);std::cout << "distance : " << distance << " " << "min.x" << p_min.z << " " << "max.z" << p_max.z << std::endl;//建立lookupTablevtkLookupTable *lut = vtkLookupTable::New();lut->Build();//设置颜色映射的数目lut->SetNumberOfTableValues(10);lut->SetHueRange(0.67, 0.0); //色调范围从红色到蓝色//设置颜色映射的范围lut->SetTableRange(p_min.z, p_max.z);加入断点会出现未为vtkcommoncore.dll加载任何符号
