2013年5月3日 · Glow: You will need to create a shader to blure the pixels around that object. I found a tutorial specific for three.js for you here: Three.js glow tutorial . There are more advanced techniques which you could try, like adding godrays .

2022年2月28日 · ThreeJS officially provides the UnrealBloom post-processor to achieve the global glow effect. We combine its source code to roughly analyze the implementation process of glow. First create a plane to hold the rendering results of subsequent image processing.

2013年4月29日 · I'm building some sort of planetary system in three.js and I spent couple of hours looking for a decent solution to get an outer glow on one planet - a sphere object with a texture. I came across this example http://stemkoski.github.io/Three.js/Selective-Glow.html which kind of does the trick, but the thing is - this form of glow also affects ...

2018年11月10日 · UnrealBloomPass applies the bloom effect to the whole render target (readBuffer). You can try to put your certain objects into a separate scene and create an additional RenderPass which acts as the input source for UnrealBloomPass. After the effect is applied, you have to blend the result on top of the entire scene.

FullScreenQuad 是 ThreeJS 封装的一个平面容器，用于保存渲染结果的纹理。 将主场景渲染到纹理. 将 rendererTarget 保存下来，作为最后混合的原始图像和阈值化输入。 在主场景渲染到纹理之后，第一步是阈值化。 图像处理中的阈值化是针对图像中的某个像素，如果像素灰度高于某个值则设为1，低于某个值则设为0。 那么在我们的原始图像中，要对阈值化进行特例化 —— 也就是说如果纹理中的灰度低于某个阈值，则颜色设为 (0,0,0)，如果高于阈值，则保留原色。 那么便可 …

2017年3月16日 · I have done quite a few hours of google search to see if this can be done within the three.js environment. I want to create a glow effect based on a TextGeometry and not a simple primitive like a ...

threex.geometricglow is a three.js extension to make any object glow at geometric level. It is done at the geometry level. An important feature which provide multiple advantages.

2024年3月9日 · In this article, we are going to get familiar with the steps we can take to create a glowing sphere in Three js. Of course, we are going to simulate the halo of the glowing sphere with the aid of...

2023年12月28日 · With UnrealBloomPass from the three.js package, that’s bloomPass.threshold. Other bloom implementations might have a slightly different name for it though. const bloomPass = new UnrealBloomPass( new THREE.Vector2( window.innerWidth, window.innerHeight ), 1.5, 0.4, 0.85 ); bloomPass.threshold = params.threshold; bloomPass.strength = params.strength;
