合并Geometries和Mesh的三个js

Question

三js ver67当前代码是这样的 -

    var materials = [];
    var totalGeom = new THREE.Geometry();
    var cubeMat;
    for (var i = 0; i < dataSetArray.length; i++) {
        var ptColor = dataSetArray[i].color;
        var value = dataSetArray[i].value;
        var position = latLongToVector3(dataSetArray[i].y, dataSetArray[i].x, 600, 1);

        var cubeGeom = new THREE.BoxGeometry(5, 5, 1 + value / 20);


        cubeMat = new THREE.MeshLambertMaterial({
            color: new THREE.Color(ptColor),
            opacity: 0.6
        });


        materials.push(cubeMat);
        // cubeGeom.updateMatrix();

        var cubeMesh = new THREE.Mesh(cubeGeom, cubeMat);
        cubeMesh.position = position;
        cubeMesh.lookAt(scene.position);

        // totalGeom.merge(cubeMesh.geometry, cubeMesh.geometry.matrix);
        //THREE.GeometryUtils.setMaterialIndex(cubeMesh.geometry, i);
        THREE.GeometryUtils.merge(totalGeom, cubeMesh);
    }


    var total = new THREE.Mesh(totalGeom, new THREE.MeshFaceMaterial(materials));
    scene.add(total);

但是我收到了消息

DEPRECATED:GeometryUtils的.merge()已移至Geometry.请改用geometry.merge(geometry2,matrix,materialIndexOffset).

在chrome dev工具中.

当我尝试类似的东西时 - totalGeom.merge(cubeMesh.geometry,cubeMesh.geometry.matrix); 而不是THREE.GeometryUtils.merge(totalGeom,cubeMesh); 我得到例外.

我将如何进行上述合并？请帮忙.

Answer 1

做这个:

cubeMesh.updateMatrix();
totalGeom.merge( cubeMesh.geometry, cubeMesh.matrix );

有关进一步了解,请参阅的源代码THREE.Geometry.merge().
