Feature Request: xBR shader and xBRZ filter for Dolphin
0%
Description
Could you please implement xBR shader or xBRZ filter or both in Dolphin. It would be very beneficial for 2D and sprite-based games.
xBR and xBRZ are pixel art scaling algorithms ,they give best results in 2D/sprite based games with low resolution textures and games with pre-rendered backgrounds which dont upscale well with higher internal resolutions. XBR/XBRZ is used with good results in emulators like Retroarch,Higan,Desmume and for example PPSSPP can use both XBRZ and increase internal resolution.
Here is explanation:http://code.google.com/p/2dimagefilter/wiki/ImageScaling#xBR
Here is comparison for 3D graphics:http://blog.metaclassofnil.com/?p=306

Source code for xBRZ is in source code of HqMAME: https://sourceforge.net/projects/hqmame/
Source Code for xBR including hybrid variants is here:
https://github.com/libretro/common-shaders
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

There is also ''Ours'' but I cant find source code for it anywhere: http://research.microsoft.com/en-us/um/people/kopf/pixelart/supplementary/
But Libdepixelize and Ours both use Kopf-Lischinski algorithm so they should have similiar effects.

Again, I personally don't see any value in such reports. While your efforts are appreciated, this is currently just a fairly random collection of links, without any actual discussion about implementation. Our issue tracker is not the place for this stuff.

Eh than what do you want ? Instead of closing this issue you should have said you dont want any links. Can I open it again without links ? And some links have discussion about implementation.

Please don't create any further issues unless you plan on implementing the feature yourself and/or can come up with an actual implementation draft.

Just because I am not programmist or emulator developer doesnt mean I shouldnt have right to suggest something by opening issue and what do mean by implementation draft ?

Supermonsterho, we are open source. If you would like to create a well written xBR shader and xBRZ filter we would be happy to review your PR on github.
We do not take feature requests normally unless they are actually missing features of the Wii or GameCube.
For all other features we have they were implemented by people who wanted them.
Thanks for your input.
