Shaders from this pack work with the OGL2 gpu plugin from Pete Bernert (www.pbernert.com).
Make sure you've got a new OGL2 plugin version and at least a pixel shader 2.0 compatible gfx. adapter.
Read the OGL2 plugin documentation for more info. 


2.2 version notes (15.5.2007)

- New folder organization.
- 2xSaI, 2xSaI CR, 2xGLSL 2.0, 2xSuperGLSL, 4xGLSLHqFilter AA, Experimental TV shaders added.
- Some shader code corrections.


2.1 version notes (11.4.2007)

- Older AA shaders (v2.o) remade, added to the collection.
- Cartoon shaders now available with or without bluring.
- Both Colored storybook shaders included.
- Daisy effect corrected, a bug in the AA v2.0 bloom shader removed.


2.0 version notes (6.4.2007)

- ColoredStorybook shader looks somewhat different, maybe nicer in some situations.
- 4xGLSL shader included (new version from 1.2v6 is now known as 4xGLSLSoft shader).
- AA shader code corrected.
- The 4xGLSLHqFilter shader (full) filters nicer, looks cool with sprite games.
- Cartoon shaders revised. IMO best 2 examples are selected.


1.2 v6 version notes (26.2.2007)

- A nicer (and slower) 4xGLSLHqFilter shader added (Full version), old version removed.
- The 4xGLSL(HqFilter) shader produces a much smoother effect, contibuting to a nicer overall appearance.
- The AA Daisy contrast effect is friendlier to the eyes. :)


1.2 v5 version notes (15.2.2007)

- v1.0 AA shaders are faster.
- v2.0 AA shaders are nicer, shader effect level matters now.
- 4xGLSL(Scale, HqFilter) shaders produce a nicer effect.


1.2 v4 version notes (28.11.2006)

- The AA shader fam. got new members (Daisy versions).
- The ColoredStoryBook shader produces a nicer effect.


1.2 v3 Version notes: (7.11.2006)

- There were some bugs in 2xGLSLHqFilter and the 4xGLSLHqFilter shader that are now fixed.
- As noticed gaussian blur does some nice AA job. I decided to include gaussian blur in one of mine cartoon shaders
  and it looks preety nice. The bb param is also lowered to prevent intense darkening on edges.
- Color brightness levels (fract part) in the cartoon shaders are calculated differently as before. Looks a bit nicer.


1.2 v2 Version notes: (25.10.2006)

- 2xGLSLHqFilter and the 4xGLSLHqFilter shaders filtering improoved.
- Cartoon shader edge detection changed a bit (borrowed from sketch shaders).
- Storybook sketch shader I drawing is now customisable (borrowed from cartoon shaders).
- A nine texel cartoon shader added.
- 2xGLSL(HqFilter) shaders run a bit faster.
- 4xGLSL(HQFilter) shaders look a bit nicer.
- Cartoon shaders are faster and easier to adapt.
- OGL2Lookup shader shows 100 pixel distances in every internal res.
- New AA(bloom) shader 2.0



1.1 Version notes: (30.8.2006)

- Color shader(s) removed.
- Cartoons shaders revision.
- New AA shaders added, old version removed.
- Minor fixes in 2x and 4x GLSL (HqFilter) shaders.


-------------------------------------------------------------------------------------------------------------------------

***AA (Bloom, Daisy) Shaders***

- Can be used for the FSAA effect.
- They can remove most of the small jaggies (like on filtered texture edges, polygons).


-------------------------------------------------------------------------------------------------------------------------


***SaL shader***

- Very fast AA shader.
- Sprite games: looks nice with 2xSaI textures, no texture filtering and internal resolutions set at least to high (shaderlvl.2)
- 3D games: some gfx. cards can't use the very-high x internal resolution. 
  SaL can be used for AA effect in higher display resolutions with theese adapers.


-------------------------------------------------------------------------------------------------------------------------


***2xGLSL shader***

- Can be used with diferent internal resolutions.
- Best suited for 2xresolutions of the PSX native mode. (like 640x480)
- Prefered settings: normal textures, no texture filtering, no fullscreen smoothing, shader level 4.
- Perfered games: sprite games.


-------------------------------------------------------------------------------------------------------------------------


***2xGLSLHqFilter shader***

- Nice adaptable smoothing.
- Quite slow, usually fast enough in 640x480.
- Can be used with diferent internal resolutions.
- Best suited for 2xresolutions of the PSX native mode. (like 640x480)
- Prefered settings: normal textures, no texture filtering, no fullscreen smoothing, shader level 4.
- Perfered games: sprite games.


-------------------------------------------------------------------------------------------------------------------------


***4xGLSL shader***

- Best suited for 4xresolutions of the PSX native mode. (like 1280x960)
- Prefered settings: normal textures, no texture filtering, no fullscreen smoothing, shader level 4.
- Perfered games: sprite games.


-------------------------------------------------------------------------------------------------------------------------


***4xGLSLScale shader***

- Best suited for 4xresolutions of the PSX native mode. (like 1280x960)
- Prefered settings: normal textures, no texture filtering, no fullscreen smoothing, shader level 4.
- Perfered games: sprite games.


-------------------------------------------------------------------------------------------------------------------------


***4xGLSLHqFilter shader***

- Does some nice looking adaptable smoothing.
- Can be used with diferent internal resolutions.
- Best suited for 4xresolutions of the PSX native mode. (like 1280x960)
- Prefered settings: normal textures, no texture filtering, no fullscreen smoothing, shader level 4.
- Perfered games: sprite games, combined sprite/3D 320x240 native res. games (AA version).


------------------------------------------------------------------------------------------------------------------------


***(Colored)Storybook shaders***

- Artistic shaders.
- The attached "gpuPeteOGL2_t1l.tga" file must be placed in the shaders folder.
- Prefered settings: shader lvl. 2-3, texture filtering 2, fullscreen smoothing, higher internal resolutions.
- Prefered games: games with 3D gfx.


-------------------------------------------------------------------------------------------------------------------------



***CARTOON SHADERS***

Cartoon shaders are customisable. The shader parameters can be changed by editing the values (th, bb...) in the fragment file.

Param. explanation:

- th: if you don't want dark lines on every (subtler) edge then raise th. If you want every edge to darken then set it to 0.0.
- bb: once the edges get past the "th check", they can be more or less intense, depending on the bb param.
- pp: the darkening on edges can be gradual or step. (0.0 darkens instantly, 2.0 very slowly)


Prefered settings: shader lvl.2 or 3, texture filtering 2, fullscreen smoothing
Prefered games:games with 3D gfx.
