My expertise in shaders and three.js is limited, however I am currently experimenting with creating a dynamic glowing effect similar to lights being flicked on and off. Currently, I am adjusting the color saturation and lightness which somewhat achieves the desired effect, but it does not look quite right to me. I wonder if there is a way to improve this using shaders or another method of color modulation. Any suggestions would be greatly appreciated.
If you're looking to add some post-processing effects to your THREE.js projects, there are several plugins available for that purpose.
One example showcasing different post processing shaders can be found here. You can explore the source code to see how they are implemented. For a complete list of official shaders, you can check out this repository. Just be mindful that not all shaders in the list are specifically meant for post-processing; those were introduced with the commit "Splitted ShaderExtras into individual files."
If you want to experiment with various filters and effects, you may find this article helpful. There's also a demo available here.
As for implementing a "glow" effect, it might require some knowledge of GLSL programming. If you have the time and interest, you could learn GLSL and create your custom shader tailored to your specific needs.
