Various fancy shaders for GZDoom ported from MariENB.
|
|
|
|
## Implemented Shaders
|
|
|
|
### Luma Sharpen
|
|
|
|
Boosts small details. Doesn't cause very noticeable halos like a typical sharpening filter.
|
|
|
|
### Grain
|
|
|
|
Makes the screen fuzzy. A couple parameters can be tweaked freely.
|
|
|
|
### Screen Dirt
|
|
|
|
Overlays a noisy pattern onto the screen to make it filthy. Not a very good filter, tbh, but I just kept it in for historical reasons.
|
|
|
|
### Color Grading Suite
|
|
|
|
Control over RGB gamma/intensity, along with a "tint" filter that, with a negative intensity, can also be used as a color booster (dunno how this even works, I wrote it 7 years ago lol). On top of all that, you can also do the same for saturation and value (not hue because that would just be dumb).
|
|
|
|
### LUT Grading
|
|
|
|
Premade lookup tables to alter color, all from the various MariENB editions I've made. More specialized LUTs will be added in the future.
|
|
|
|
### Technicolor
|
|
|
|
A filter that enhances color in some way, I don't know the technical details.
|
|
|
|
### Color Matrix
|
|
|
|
General purpose color mixing. The matrix is normalized in post. For experienced users.
|
|
|
|
### Hue-Saturation
|
|
|
|
The GIMP filter in shader form. Allows shifting the hue and tweaking the saturation and value of red, yellow, green, cyan, blue and magenta ranges.
|
|
|
|
### BlurSharpShift
|
|
|
|
Blurring followed by sharpening, followed by chromatic aberration. This is a meme filter chain that a lot of people love for some reason, claiming it adds "photorealism" or something.
|
|
|
|
### Vignette
|
|
|
|
Darkens the edges of the screen. Comes with "border blur", which also blurs said edges.
|
|
|
|
### RetroFX
|
|
|
|
A combo of downscaling and palette reduction (with optional dither), which has been a staple of MariENB for years. There's a multitude of palettes available to choose from. Most IWADs are covered, along with some notable megawads, various DOS games, and a couple "standard" palettes.
|
|
|
|
Not available yet are the features for aspect ratio correction, overscan/underscan or the old CRT filter (which wasn't exactly all that good, really).
|
|
|
|
## Missing Shaders
|
|
|
|
### Bloom
|
|
|
|
It's very unlikely that this one will be added, unless I can hack something horribly using camera textures, idk.
|
|
|
|
### Depth of Field
|
|
|
|
Not a chance, this thing very blatantly needs Depth Buffer access, which is impossible in GZDoom thanks to portal rendering.
|
|
|
|
### Tonemap
|
|
|
|
Not needed, GZDoom implements its own.
|
|
|
|
### Screen Frost / Heat Haze
|
|
|
|
These aren't "general purpose" enough to be included.
|
|
|
|
### Paint Filter
|
|
|
|
Might add it, maybe???
|
|
|
|
### SMAA
|
|
|
|
This needs to be part of GZDoom, honestly. |
