Aaron Giles 2ccc0a290a bgfx: Disable lowpass filter by default by setting it to its maximum value, since it does not account for actual monitor type. We can revisit this decision in the future if better monitor information is provided from the driver. 2021-03-23 09:31:32 -07:00
cgwg 931f85ee27
bgfx: crt-geom and crt-geom-deluxe enhancements (#7872) 
* Made spot size parameters adjustable also increased samples from 2 to 3 scanlines for crt-geom-deluxe.
* Made horizontal interpolation adjustable.
* bgfx crt-geom-deluxe: Made phosphor decay smoothly to zero at specified cutoff time.
* bgfx crt-geom-deluxe: Added lowpass filter.

cgwg 92b2921754
bgfx: crt-geom and crt-geom-deluxe enhancements (#7766) 
Added a "brightness boost" feature for the shadow mask that works by making the brightness ratio between bright and dark mask pixels closer to 1 for the brighter parts of the image.

Added clamping to zero so that underscanning produces a black border.

Added a "raster bloom" effect to crt-geom-deluxe that makes the image grow slightly when the average brightness of the screen is high, mimicking a common defect in CRTs.

Jeremy Green 3697bd8cdc Added crt-geom and crt-geom-deluxe shaders for bgfx. 
This includes several aperture grille / shadow mask patterns. Note that these are all designed to be used on a display with RGB subpixel order, and may thus suffer if rotated or used with a BGR display.
