对选定网格进行后处理 [英] Post-processing to selected meshes

问题描述

在three.js中，是否可以仅将后处理效果应用于选定的网格?

例如，具有带颗粒效果的立方体，而场景的其余部分则没有. 谢谢！

解决方案

是. three.js示例，其中显示了如何使用遮罩将后处理应用于选定的网格. >

我认为可以提高示例的清晰度，但是您可以像这样修改示例:

composer4 = new THREE.EffectComposer( renderer, new THREE.WebGLRenderTarget( rtWidth, rtHeight, rtParameters ) );

composer4.addPass( renderScene );
composer4.addPass( renderMask );
composer4.addPass( effectDotScreen );
composer4.addPass( clearMask );
composer4.addPass( effectVignette );

您将获得如下输出:

这是一个复杂的示例，因此您将必须仔细研究.

In three.js is it possible to apply postprocessing effects only to selected meshes?

For example to have a cube with grain effect while the rest of the scene does not have it. Thank you!

解决方案

Yes. There is a three.js example that shows how to apply postprocessing to selected meshes using masking.

I think that example can be improved for clarity, but you can modify the example like so:

composer4 = new THREE.EffectComposer( renderer, new THREE.WebGLRenderTarget( rtWidth, rtHeight, rtParameters ) );

composer4.addPass( renderScene );
composer4.addPass( renderMask );
composer4.addPass( effectDotScreen );
composer4.addPass( clearMask );
composer4.addPass( effectVignette );

You will get an output like this:

It is a complicated example, so you will have to study it carefully.
