Lens Distortion

镜头失真

Basic 基础

Lens Distortion

镜头失真

Left without, right with the Lens Distortion post effect. Note how the 3D objects (if you can make them out …) have been distorted accordingly. 左边没有，右边的镜头扭曲后的效果。请注意3D 对象(如果您能够辨认出它们...)是如何相应地被扭曲的

The Lens Distortion post effect (note that this is a real render effect despite its categorization as a post effect) is based on a lens profile that was loaded (see also Lens Distortion tool with regard to this). When rendered, all 3D objects will be distorted according to this lens profile, just as if the scene were filmed using a real-world camera with lens distortion.

镜头扭曲后效果(注意，这是一个真正的渲染效果，尽管它的分类为后效果)是基于一个镜头配置文件加载(也参见镜头扭曲工具有关这一点)。渲染时，所有的3D 物体都会根据这个镜头的轮廓进行扭曲，就好像这个场景是用真实世界的摄像机拍摄的。

This serves to believably adapt 3D objects to distorted image material.

这可以令人相信地使3D 物体适应扭曲的图像材质。

The following applies in conjunction with the Lens Distortion shader:

下面的应用与镜头失真着色器:

If the Lens Distortion post effect is enabled, the Lens Distortion shader will be disabled and vice-versa. 如果镜头失真AE启用，镜头失真着色将被禁用，反之亦然

Only then will the rendered 3D objects match the image. The background object - as an only exception - will itself be ignored by the Lens Distortion post effect. It most often already has the image assigned to it, which makes an additional distortion superfluous.

只有这样，渲染的3D 对象才能与图像匹配。背景物体-作为唯一的例外-本身将被镜头失真AE忽略。它通常已经有分配给它的图像，这使得额外的失真变得多余。

Tip: 提示:
Note that texturing via camera projection may not work with this function because regions that lie outside of the camera projection can become visible when rendered with the Lens Distortion post effect. 请注意，通过相机投影纹理可能不工作与这个功能，因为区域位于相机投影可以成为可见时，镜头变形AE渲染 Tip 2: 贴士二:
If you want to achieve a fisheye effect, this can be done using this shader. Simply create a pseudo lens profile ( 如果你想获得鱼眼效果，可以使用这个着色器。只需创建一个伪透镜配置文件(Lens Distortion Model 镜头畸变模型3DE Radial Fisheye Degree 8 三维径向鱼眼8度 with higher 用更高的Quartic 四次的 and 及Quadratic 二次型 values) and load it: 值) ，然后载入:

Model: Steen Winther 型号: Steen Winther

Of course you don’t have to only use a pseudo lens profile. If you use the Lens Distortion tool with a fisheye view in order to make the lens distortion as realistic-looking as possible you will have a fairly realistic-looking fisheye effect.

当然，你不必只使用伪镜头轮廓。如果您使用镜头失真工具与鱼眼视图，以使镜头失真尽可能现实的外观，你将有一个相当现实的外观鱼眼效果。
