掌握X3D 第二节

主要内容：外观

材质 Material

Appearance 外观节点
Material 材质节点
•diffuseColor 决定色彩
<Shape>
<Appearance>
<Material diffuseColor="1 1 0" />
</Appearance>
<Box />
</Shape>
色彩的值为RGB值，可用photoshop查色并计算。
shininess 光亮程度
transparency 透明度
<Material diffuseColor="1 1 0" transparency="0.9"/>
ambientIntensity 环境色彩强度
emissiveColor 色彩的放射程度
specularColor 色彩的反射形式
<Material diffuseColor="1 1 0" emissiveColor="0 0 1" specularColor="1 0 0"/>
