BabylonJS - 高光

当光线照射到 Specular（高光）属性时，该属性会反射出像镜子一样的效果。Specular（高光）提供了两个属性：specularColor 和 specularTexture。颜色和纹理在光线照射的方向上显示。它就像网格上的聚光灯。可以在下面的示例中看到相同的效果。

高光颜色的语法

materialforbox.specularColor = new BABYLON.Color3(1.0, 0.2, 0.7);

高光纹理的语法

materialforbox.specularTexture = new BABYLON.Texture("grass.png", scene);
