BabylonJS - Specular
Specular 属性在光线照射到其上时会产生像镜子一样的反射。Specular 提供两个属性 specularColor 和 specularTexture。颜色和纹理在光线照射的方向上很明显。它的行为就像网格上的聚光灯。您可以在下面的演示中看到相同的内容。
镜面反射颜色的语法
materialforbox.specularColor = new BABYLON.Color3(1.0, 0.2, 0.7);
镜面反射纹理的语法
materialforbox.specularTexture = new BABYLON.Texture("grass.png", scene);
