[Release] New Shaders for HD users

[Buttercraft]

z-cubic is a "keys cubic" so called ideal filter based on the formula B+2C=1 (similar to Mitchell Netravali but maximally sharper)

z-cubic-soft is one tap softer, looks nice with cartoon style graphics as in war2, trees render a bit like remaster.

z-cubic-sharp is one tap sharper than z-cubic, some may prefer this.

Place them in your Shaders directory and modify the shader= line in ddraw.ini/dd-hd.ini

Code: [Select]

shader=Shaders\z-cubic-bilinear.glsl

Do you have any pictures to show before and after? Like what does this add?

I saw no difference at all between any of these 3 nor any difference compared to bilinear.  It appears they dont actually "do" anything at all.  The other shaders all work fine and do produce noticeable differences when using opengl.

Thanks for your input Lance, I forgot to add the bilinear switch.

Better visuals, cat-rom was not designed for computer graphics (see bottom of this page).

Catrom and B-spline are extreme opposites. Mitchell Netravali splits the difference, but still sits on the blurry side.

This is as sharp as you can push before you see similar types of artifacts.
