Notes: This shader does scaling with a weighted linear filter
|
||||
based on the algorithm by Iñigo Quilez here:
|
||||
https://iquilezles.org/articles/texture/
|
||||
but modified to be somewhat sharper. Then a scanline effect that varies
|
||||
based on pixel brightness is applied along with a monochrome aperture mask.
|
||||
This shader runs at ~60fps on the Chromecast HD (10GFlops) on a 1080p display.
|
||||
(https://forums.libretro.com/t/android-googletv-compatible-shaders-nitpicky)
|
||||
|
||||
Dogway: I modified zfast_crt.glsl shader to include screen curvature,
|
||||
vignetting, round corners and phosphor*temperature. Horizontal pixel is left out
|
||||
from the Quilez' algo (read above) to provide a more S-Video like horizontal blur.
|
||||
The scanlines and mask are also now performed in the recommended linear light.
|
||||
For this to run smoothly on GPU deprived platforms like the Chromecast and
|
||||
older consoles, I had to remove several parameters and hardcode them into the shader.
|
||||
Another POV is to run the shader on handhelds like the Switch or SteamDeck so they consume less battery.
