一、效果图
二、代码
1 //创建一个三维曲面对象
2 Q3DSurface surface; 3 surface.setFlags(surface.flags() ^ Qt::FramelessWindowHint); 4 //创建数据对象
5 QSurfaceDataArray *data = new QSurfaceDataArray; 6 QSurfaceDataRow *dataRow1 = new QSurfaceDataRow; 7 QSurfaceDataRow *dataRow2 = new QSurfaceDataRow; 8 //为数据对象赋值
9 *dataRow1 << QVector3D(0.0f, 0.1f, 0.5f) << QVector3D(1.0f, 0.5f, 0.5f); 10 *dataRow2 << QVector3D(0.0f, 1.8f, 1.0f) << QVector3D(1.0f, 1.2f, 1.0f); 11 *data << dataRow1 << dataRow2; 12 //创建序列，加入数据，添加到Q3DSurface
13 QSurface3DSeries *series = new QSurface3DSeries; 14 series->dataProxy()->resetArray(data); 15 surface.addSeries(series); 16 surface.show();
