漩涡图像特效是指在一个圆形区域内扭曲所渲染的图像。图像中的像素沿着一个圆形区域进行旋转偏移,而偏移量随着距中心的距离而逐渐减少,在圆形区域边界处降低为0。漩涡图像特效类似于另一种叫做旋转扭曲的图像特效,不同的是旋转扭曲特效是将图像沿着一个点而非一个圆形区域来旋转图像。
The Vortex image effect distorts the rendered image within a circular region. Pixels in the image are displaced around a central circular area by a specified angle; the amount of displacement reduces with distance from the centre, diminishing to zero at the circle's edge. Vortex is similar to another image effect called Twirl, although Twirl distorts the image around a point rather than a circle.
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。
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.
