Three js merging Geometries and Mesh
提问by Abhishek
Three js ver67 Current code something like this -
三个 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);
However I get the message
但是我收到消息
DEPRECATED: GeometryUtils's .merge() has been moved to Geometry. Use geometry.merge( geometry2, matrix, materialIndexOffset ) instead.
已弃用：GeometryUtils 的 .merge() 已移至 Geometry。使用 geometry.merge( geometry2, matrix, materialIndexOffset ) 代替。
in chrome dev tools.
在 chrome 开发工具中。
When I try something like - totalGeom.merge(cubeMesh.geometry, cubeMesh.geometry.matrix); instead of THREE.GeometryUtils.merge(totalGeom, cubeMesh); I get exceptions.
当我尝试类似 - totalGeom.merge(cubeMesh.geometry, cubeMesh.geometry.matrix); 而不是 THREE.GeometryUtils.merge(totalGeom, cubeMesh); 我得到例外。
How will I do the above merge? Please help.
我将如何进行上述合并？请帮忙。

Do this:
做这个：
cubeMesh.updateMatrix();
totalGeom.merge( cubeMesh.geometry, cubeMesh.matrix );
For a further understanding, see the source code of THREE.Geometry.merge().
更深入的理解，请参见 的源代码THREE.Geometry.merge()。
