This is a work-in-progress CRT simulation, prototyped in Taichi and implemented as a set of Slang shaders for RetroArch or librashader-compatible software.

Currently, supported features include:

• A configurable low-pass filter to simulate the limited bandwidth of an analog connection.
• Optional YIQ encoding to simulate a composite or s-video connection (actual NTSC encoding/decoding is not currently supported).
• Configurable scanline simulation.
• Configurable overscan cropping.
• "Glow" simulation, recreating the glowing areas around bright parts of the screen caused by the scattering of light in the glass.
• Limited support for masks in the Taichi simulation only.

The Slang shaders have been tested to run in 4k at 60 FPS on a Ryzen 7000 integrated GPU in their default configuration.
