Not entirely sure how complex this is, I haven't really looked deeply into the differences in signal, decoding, and artifacts yet.

Add explicit support for PAL/SECAM signal emulation as well.

Add more preset NTSC timing data (for instance, get the timings for Sega Genesis games, so that emulators will get that classic rainbow-like waterfall effect in Sonic).

Some things that are on the list to do at some point: More extensive documentation coming soon! Roadmap

Sorry, Linux/Mac users: the demo code is rather Windows-specific at the moment, but hopefully it still gives you the gist of how to hook everything upĪ small overview of using the C++ code can be found here.GL-Sample: A sample Visual Studio 2022 project that runs Cathode Retro in OpenGL 3.3 core.D3D11-Sample: A sample Visual Studio 2022 project that runs Cathode Retro in Direct3D 11, as HLSL shaders.Samples: Some C++ samples for how to use Cathode Retro.

More instructions on how to use the C++ code in the next section.Code requires at least C++14, and has been tested in Visual Studio 2022, and with Clang 9, Clang 17, GCC 8.1, and GCC 13.2.

Include/CathodeRetro: Header-only C++ code to support a CathodeRetro::CathodeRetro class that handles running all of the shader stages for the full effect.See GLHelpers.h in Samples/GL-Sample for an example of this if needed Compiling for GLSL requires a loader that handles #include directives, as well as requires a #version directive (at least #version 330 core).Compiling the shaders as HLSL requires an HLSL preprocessor definition be added (either by the compiler via the command line or manually at the top of cathode-retro-util-language-helpers.hlsli.While the shader files' extension is hlsl, these shaders will compile as either HLSL or GLSL, due to some macros in cathode-retro-util-language-helpers.hlsli.Shaders: All of the shader source files.

#Cathode ray tubes in tv 1080p

Best at 1080p resolution and higher (great at 4k!).

Approximation of CRT diffusion (the light from the TV refracting through imperfections in the glass face).

Supports emulation of shadow mask, slot mask, and aperture grille TVs.

Flat or curved screens, with optional edge and corner rounding.

Emulate an image being displayed through a CRT monitor.

Has correct emulation of NTSC composite artifact colors.

Tint/Saturation/Brightness/Sharpness 'knobs' controls, like a TV had!.

Noise, picture instability, and ghosting for that 'my TV has bad reception' feel.

Built-in scanline timings to emulate NES/SNES and PC Composite (320- and 640-wide) displays, but flexible enough to emulate any timings.

At arbitrary resolutions (not limited to standard NTSC limitations).

Emulate composite and S-Video NTSC signals.

Screenshot from an old, unreleased brick-breaking game Features Image of Amarelo tileset by Adam Saltsman (click screenshots for full-sized version) Cathode Retro is a collection of shaders that combine to emulate the properties and artifacts of a color NTSC TV signal as well as the visual look of a Cathode-Ray Tube (CRT) TV.
