Unity組件：Crease 折皺特效（輪廓線）

The Crease is a common non-photorealistic (NPR) rendering technique that enhances the visibility of objects by adding outlines of variable thickness.

折皺效果是一常見的非真實感 (NPR) 渲染技術，它通過增加物體加輪廓變厚度來增強該物體的可見性。

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.

和其他圖像特效一樣，該特效只能在Unity Pro上進行使用，并且在使用之前必須安裝Pro Standard Assets。

  模糊半徑，決定了輪廓線的粗細

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.

這個特效需要顯卡擁有像素著色器（2.0）或者OpenGL ES 2.0，另外需要支持深度紋理。臺式機：2004年以后的NVIDIA顯卡（GeForce 6），2004年以后的AMD顯卡（Radeon 9500），2006年以后的Intel卡（GMA X3000）；移動設備：OpenGL ES 2.0并支持深度紋理；控制臺： Xbox 360、 PS3。

All image effects automatically disable themselves when they can not run on end-users graphics card.

所有圖像特效如果無法在用戶顯卡上運行時將會自動被關閉。
