new Primitive3D(参考primitive, positionopt, scaleopt)

Example

const instance = new Cesium.GeometryInstance({
             geometry : new Cesium.PlaneGeometry({
                 vertexFormat : Cesium.VertexFormat.POSITION_ONLY
             });
         });
         let primitive3D = viewer.scene.primitives.add(new Cesium.Primitive3D({
              geometryInstances: instance,
              appearance: new Cesium.MaterialAppearance({
                  material: Cesium.Material.fromType(Cesium.Material[value])
              }),
              position: [117.090795612294, 31.15224105521026, 1000],
              scale: [500, 500, 1]
          }));
