BabylonJS - 環境

此處，環境顏色是場景環境顏色。要將環境顏色應用於材質，您需要將 ambientColor 新增到場景。

例如，scene.ambientColor = new BABYLON.Color3(0.3, 0.3, 0.3);

語法

請考慮與 AmbientColor 相關的以下示例。

materialforbox.ambientColor = new BABYLON.Color3(1, 0, 0.2);

環境紋理

要應用環境紋理，您需要一張影像。

我們使用了一張名為 nature.jpg 的影像，將它儲存在 images/ 資料夾中並在本地使用。您可以下載您選擇的任何影像並用作紋理。

語法

materialforbox.ambientTexture = new BABYLON.Texture("images/nature.jpg", scene);
