using echarts-4.1.0,echarts-gl-1.1.1, in globe I used scatter3D to draw a scatter chart. The tooltip configured in option can be displayed normally, but it is normal to use dispatchAction to exhale tooltip, in the same way that I put it in the 2D diagram.

var globel = echarts.init(document.getElementById("globe"));
        
        const option = {
            // backgroundColor: "-sharp000",
            visualMap: {
                show: false,
                min: 0,
                max: 60,
                inRange: {
                    symbolSize: [1.0, 10.0],
                    opacity:[1,0.5]
                }
            },
            tooltip: {
                trigger: "item",
                alwaysShowContent:true,
                formatter: function(prams,d,callback){
                    return prams.value
                },
            },
            globe: {
                baseTexture: require("../assets/world.png"),
                globeOuterRadius: 100,
                displacementScale: 0.1,
                viewControl:{
                    autoRotate:false
                },
                postEffect:{
                    bloom:true,
                    screenSpaceAmbientOcclusion:true
                },
                shading: "color",
                z: 9
            },
            series: {
                type: "scatter3D",
                coordinateSystem: "globe",
                blendMode: "source-over",
                symbolSize: 2,
                itemStyle: {
                    // color: "rgb(148, 148, 148)",
                    color:"-sharpb4b4b4",
                    opacity: 1
                },
                data: data
            }
        }

        globel.dispatchAction({
