@WA - it's fun to experiment.

How VERY true Maestro . 😊. Updated the last zip with a scene including all your suggested options
for tweeking mouse coordinates and zoom in old FG140 . I have applied uniforms there which can be easily
varied by users at the .SCN level. The new scene now included is FG140WA.scn which deploys the shader GoldballsMod02WA.fsh

@ComteDracula . répéter re-télécharger / extraire est nécessaire:
https://scenes.virtuastripper.net/ET_FractalGarden137-142.zip
zip size = 265 Kb

Merci de votre patience. Je promets que c'est la dernière mise à jour appliquée pour cet ensemble 137-142

@EvethangForever, Sorry, but 140WA is not working. It stays with a beige background.

@EvethangForever, Désolé, mais 140WA ne fonctionne pas. Il reste avec un fond d'écran beige.

In the Scn file FG140WA.scn

fix the name of the shader

From this

shader: fragment,Shaders/GoldballsMod02A.fsh

to this

shader: fragment,Shaders/GoldballsMod02WA.fsh

I made the change and FG140WA.scn works now. Thanks @Wyldanimal. 😊

J'ai fait le changement et FG140WA.scn fonctionne maintenant. Merci @Wyldanimal. 😊

Thanks again @Wyldanimal & @ComteDracula .. a case of me not seeing the forest for da trees typographically
so to speak.😊 Apologies..all good now guys !!!!!

Loving it so far (Fg127-148) but I can't test 'em all for smoothness just now. Race is on. Oh, but to go back a bit, FG125 is beige and FG126 is white screen of ***** disappointment. 😕😄

Have a great one. 👍😎

@Socialhazard good to see you back 👍pal ..
So FG125 and 126 are not compiling on your rig (?)
Thats interesting. Check you have the most recent updates
Lots of the earlier ones (same zip name) were wonky..first tries etc..
Nevertheless,I will look into it soon..Thanks lots ✌

@EverthangForever

Thanks. 😀 No need to look into it. That worked, probably should have thought of that myself. 😳 😄 👍 😎

Edit: FG117 runs way slow, FG117A runs somewhat slow (seems to depend on the card), and FG148 and FG153 runs just a lil' slow.

I have started to pay more attention to
reducing the amount of stuttering movement
of models when a processor intensive shader
is used in a scene.

This occured after a recent WebGL conversion
https://scenes.virtuastripper.net/ET_FractalGarden165.zip
zip size = 5.72 Kb

The stuttered movemnt of the models was so bad
I had to re-edit both the shader and the .SCN
( as below) to make it watchable. To do this..
In the .SCN file:

1. Removed the shader's substrate texture altogether
and replaced that source with a nested quad at the
framebuffer to mount the shader.

framebuffer {
id: myquad01
size: 960, 540
quad {
size: 960, 540 //1920, 1080
hotspot: 0.0, 0.0
pos: 0, 0, 0
shader: fragment, Shaders/Undulating ColumnsMod01.fsh
}
}

2. Reduced the amount of processing required by using
a smaller sized quad (half the size of the original
1920 x 1080 mounting texture). you can go smaller but
the edges of graphics may start to break up.

3. At the sprite node used that same size to declare
the output of the shader as a 'sprite'. This also
allowed me to invert the shader output which I could
not have done if I had applied the shader directly on
a texture in the sprite node.

sprite {
hotspot: 0.5, 0.5
pos: 0, 0, 0
source: myquad01
size: 960, 540
scale: 1.0, -1.0// inverts the previous shader
}

4. Used Z placement of the 3D camera to best fit the shader
'sprite' for the screen rather than re-scaling the 'sprite'

In the shader:
Reduced precision from mediump to lowp

#ifdef GL_ES
precision lowp float;
#endif

By making the above changes, the stuttering became way less
noticeable. The only drawback to removing my 'good old' Beige.png
shader substrate is that slight artifacts are created now whenever
the clipnamesprite or logo become active.

@EverthangForever,

I don't know if your scene was finished, but I uploaded your last link above of your scene, and I have a white wallpaper on ET_FractalGarden165. Thanks.


@EverthangForever,

Je ne sais pas si votre scène était terminée, mais j'ai téléchargé votre dernier lien plus haut de votre scène, et j'ai un fond d'écran blanc sur le ET_FractalGarden165. Merci.

Merci @ComteDracula,
Je pense avoir trouvé le problème.
Il a besoin de swizzles sur la ligne 179 et la ligne 186
Si cela fonctionne ici, je vais charger ces modifications et vous pouvez voir si cela compile

Thanks @ComteDracula,
I think I have found the problem.

It needs swizzle on line 179 change to
render(rc, gl_FragCoord.xy + vec2(x, y) / float(AA));

and swizzle on line 186 change to
texelFetch(iChannel1, ivec2(gl_FragCoord.xy) & 1023, 0).rgb / 200.;

If that works here, I will upload these changes and lets see if it compiles
edit: swizzle changes made to FG165 and zip re- uploaded

Merci pour tout ce travail @EverthangForever J'ai enfin eu le temps d'installer E.T Fractal 122 à 154 et tout est bien 👍
Je viens d'essayer FG165 mais mon fond reste gris-blanc 😟
Thank you for all this work @EverthangForever I finally had time to install E.T Fractal 122 to 154 and everything is fine 👍
I just tried FG165 but my background remains gray-white 😟

Merci @Philours pour vos aimables paroles.
FG165 est un problème mais rien ne montre de défaut sur mon PC,
Votre vghd.log affiche-t-il une erreur ?

Thank you @Philours for your kind words.
FG165 is a problem however nothing shows fault on my PC,

I don't know about @ComteDracula, we'll wait for news 😊 But yes my machine is not HIGH_TECH 😀

@Philours bon de vous voir répondre ici. Votre aide est très précieuse.
Il semblerait que les shaders Shadertoy produisent beaucoup plus de ces erreurs ces derniers temps dans
systèmes graphiques plus anciens.
Désormais, il peut être nécessaire pour nous de n'utiliser que des shaders GLSLSandbox qui utilisent une version inférieure de GLSL à l'avenir.

It would appear Shadertoy shaders are producing many more of these errors lately in
older graphics systems.

Henceforth, It may be necessary for us to only use GLSLSandbox shaders which use a lower version of
GLSL in future.

Voici pour moi.

Similar problem as @ComteDracula .

ET FG165

For the shader
Undulating ColumnsMod01.fsh

add this header as the 1st 3 lines

#version 460
#extension GL_EXT_gpu_shader4 : enable
#define lowp

then delete the entire line starting #extension on line 15

#extension GL_EXT_gpu_shader4 : enable

then add the Swizzle on line 165
Change it from this

gl_FragColor.rgb += textureLod(iChannel0, r, 5.).rrr * fr * sh2;

to This

gl_FragColor.rgb += textureLod(iChannel0, r.xy, 5.).rrr * fr * sh2;

Also
none of this is used in the shader so it can all be deleted

#define PI 3.141592654
#define iMouse AUTO_MOUSE
#define MOUSE_SPEED vec2(0.5,0.577777) * 0.2
#define MOUSE_POS vec2((1.0+cos(iTime*MOUSE_SPEED))*u_WindowSize/2.0)
#define MOUSE_PRESS vec2(0.0,0.0)
#define AUTO_MOUSE vec4( MOUSE_POS, MOUSE_PRESS )

don't delete this line, it's needed

const float pi = 3.14159265358979323;

Since iStripper doesn't support input channels the same as that of ShaderToy
we can eliminate all of the codes related to the HDR input and texturing input

and we aren't making AA passes, so we can get rid of the AA loops.

here is then whats left.
