[Unity 组件参考手册]组件：图像特效脚本之折皱特效（轮廓线）

.

The Crease is a common non-photorealistic (NPR) rendering technique that enhances the visibility of objects by adding outlines of variable thickness.折皱效果是一常见的非真实感 (NPR) 渲染技术，它通过增加物体加轮廓变厚度来增强该物体的可见性。As with the other image effects, this effect is only available in Unity Pro and you must have the Pro Standard Assets installed before it becomes available.和其他图像特效一样，该特效只能在Unity Pro上进行使用，并且在使用之前必须安装Pro Standard Assets。
Crease shading creates depth based outlines.
折皱特效渲染的基于深度的轮廓线。
[Properties 属性]------------------------------------------------------------------------Intensity 强度
    The intensity of the crease shading.
    折皱着色的强度
    Softness 柔软度
    The smoothness and softness of the applied crease shading.
    应用于轮廓线光照的柔软度与顺滑度
    Spread 扩散半径
    The blur radius, which also determines the thickness of outlines.
    模糊半径，决定了轮廓线的粗细 ------------------------------------------------------------------------[Hardware support 硬件支持]This effect requires a graphics card with pixel shaders (2.0) or OpenGL ES 2.0. Additionally, depth texture support is required. PC: NVIDIA cards since 2004 (GeForce 6), AMD cards since 2004 (Radeon 9500), Intel cards since 2006 (GMA X3000); Mobile: OpenGL ES 2.0 with depth texture support; Consoles: Xbox 360, ps3.这个特效需要显卡拥有像素着色器（2.0）或者OpenGL ES 2.0，另外需要支持深度纹理。台式机：2004年以后的NVIDIA显卡（GeForce 6），2004年以后的AMD显卡（Radeon 9500），2006年以后的Intel卡（GMA X3000）；移动设备：OpenGL ES 2.0并支持深度纹理；控制台： Xbox 360、 PS3。All image effects automatically disable themselves when they can not&nbsp***n on end-users graphics card.所有图像特效如果无法在用户显卡上运行时将会自动被关闭。【来源：互联网】
