What this actually seems to be is a plain old bloom filter that happens to have horizontal lines overlaid.
- bsimpson 10mo agoA better demo would correlate the pixelization of the source with the settings in the sidebar. Doesn't even have to be part of the shader, but would convey the effect better. The animated shapes toggle really kills the illusion.
- msephton 10mo agoThe animated shapes are off by default. They're there only so you can see how the settings affect red, green, and blue individually and in motion. For example with some settings the scanlines tend to disappear on red when in motion.
- msephton 10mo agoYeah it's not a CRT simulator. It's a minimal shader to give a CRT-like vibe. Minimal as in the least amount of processing, so it performs well on older devices.
- JKCalhoun 10mo agoA Bloom filter? Never mind, I'm guessing you mean a different kind.
- flohofwoe 10mo agoIn rendering, bloom filter means this thing: https://en.wikipedia.org/wiki/Bloom_(shader_effect) https://en.wikipedia.org/wiki/Bloom_(shader_effect) ...the other Bloom filter is named after a person.
