BabylonJS - 線狀網格

在本節中，我們將學習如何建立一個線狀網格。

語法

以下是建立線狀網格的語法。

var lines = BABYLON.Mesh.CreateLines("lines", [
   new BABYLON.Vector3(-10, 0, 0),
   new BABYLON.Vector3(10, 0, 0),
   new BABYLON.Vector3(0, 0, -10),
   new BABYLON.Vector3(0, 0, 10)
], scene);

引數

考慮以下引數以建立線狀網格 -

名稱 - 線狀網格的名稱。
陣列 - 向量陣列。
場景 - 顯示線狀網格的場景。
