250 demos converted and counting...

[Stefan]

Instead of making further single forum topics, i'll add new demos here in future.

Download 250 converted demos here

Incl. some WIP demos that compile successfully, but fail to render properly.
Sort by date to catch the recently converted ones and don't forget to copy the textures.

All texture cubes are linked to the only one that comes with MadShaders.
No music, no keyboard support yet.

Nice!

Maybe you could manually merge all previous topics (one by one) with this one...

I merged the old topics without replies to avoid confusion.


Go here for the picture loader with "AMD R300 picture quality teaser" mentioned in the news: https://goo.gl/6lwNlD (42 MB)

100 demos converted now.

Sort by date to catch the new ones.

For some reason Shadertoy demo "Volcanic" is screwed in GLSL Hacker.

[Stefan]

Besides Shadertoy conversions the update contains shaders from GLSL.IO
Thanks to aiekick at Shadertoy who made the formula "float progress = sin(iGlobalTime*.5)*.5+.5;"

At GLSL.IO the pictures are pumped into the pipeline via JavaScript.
Don't know how to do that in GLSL Hacker, so i'm limited to 2 pictures.

[JeGX]

I'll try to post a demo asap that displays several images that should help you.

[Stefan]

Yet 20 more demos, watch the "train ride" at least 2 minutes.

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

The other day i stumbled upon a japanese GLSL editor at "JS4K intro"
"Planets" is the only demo that shows more than nothing.

Don't know how to get the value "p" for the vertex shader (so i used the VS that comes with GLSL Hacker)

Code Select Expand

// http://jp.wgld.org/js4kintro/editor/script.js   
attribute vec3 p;void main(){gl_Position=vec4(p,1.);}

I'm quite sure i converted the fragment shader correctly. Actually i found another difference between AMD and NVIDIA.

Code Select Expand

// http://jp.wgld.org/js4kintro/
#version 130 // mandatory for precision qualifier with AMD GPUs - NVIDIA doesn't care
precision mediump float;
//uniform float t;
//uniform vec2  r;
uniform vec2      iResolution;     // viewport resolution (in pixels)
uniform float     iGlobalTime;     // shader playback time (in seconds)
#define t iGlobalTime
#define r iResolution




edit: typo fixed

[JeGX]

There is no standard name for the vertex shader inputs but usually there is always the position. In your case:

Code Select Expand


// http://jp.wgld.org/js4kintro/editor/script.js   
attribute vec3 p;void main(){gl_Position=vec4(p,1.);}


replace  "attribute vec3 p" by "in vec4 gxl3d_Position" :

Code Select Expand


#version 150
in vec4 gxl3d_Position;
void main()
{
  gl_Position = gxl3d_Position;
}


[Stefan]

replace  "attribute vec3 p" by "in vec4 gxl3d_Position" :

Thanks for the heads-up.
It compiles successfully, but it makes no difference visually.

[JeGX]

Could you paste the pixel shader ?


I coded a simple slideshow demo :

I hope that demo will help you with your transition effects.

Check out WIP_JS4K_planets_gl2.xml in the updated package at https://goo.gl/mSE7mc

Thanks for the demo, i'll study it

[Stefan]

I found a shader tool named esfragt for Windows and Raspberry.
It renders "JS4K  planets" properly.

I made a package where you just have to run planets.bat

[Stefan]

Download again for 150 demos now

I got "Venice" working now, just forgot to load the textures. And this demo rocks.

The AMD vs. NVIDIA saga continues: the demo "Illustrated equations" contains a line that's only illegal with AMD GPUs.
Actually the line is redundant.

Code Select Expand

// gl_FragCoord.y *= ratio;  // l-value required: assign "gl_FragCoord" (can't modify gl_FragCoord)

[Stefan]

Another day, another issue:

the demo "Ice Lake" uses a negative resolution "-iResolution", which causes a black screen in GLSL Hacker.
As a workaround i replaced it with "-1 * iResolution"

Download converted demo from https://goo.gl/udrmeK

[Stefan]

Go Portugal! fixed, hope it makes at least one forum user happy.

Problem was the undefined surfacePosition (reminder to myself: this might help in future with other GLSLSandbox demos).

Code Select Expand

uniform vec3      iResolution;     // viewport resolution (in pixels)
uniform float     iGlobalTime;     // shader playback time (in seconds)
uniform vec4      iMouse;          // mouse pixel coords. xy: current (if MLB down), zw: click

#define time iGlobalTime                                             //uniform float time;
#define mouse iMouse                                                 //uniform vec2 mouse;
#define resolution iResolution                                       //uniform vec2 resolution;
vec2 surfacePosition = gl_FragCoord.xy / iResolution.xy * 1.4 - 0.7; //varying vec2 surfacePosition;

I live in Portugal!

Frozen Wasteland

Subroutine FOUR-D_NOISE disabled, causes implicit cast from "vec4" to "vec2" .

>>>download converted demo from here<<<

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

Water Landscape

totally screwed in GLSL Hacker for some reason

>>>download converted demo from here<<<

[Stefan]

I was a bit puzzled how the micro shaders at Shadertoy work, but i think i found a good formula now:

Replace Shadertoy's pixel shader code  void mainImage( out vec4 f, vec2 w ) with:

Code Select Expand

#define f gl_FragColor
// modify values until it fits
#define objectsize 500
#define leftright 0
vec2 w = gl_FragCoord.xy / iResolution.xy * objectsize + leftright;
void main()

crowded place -> converted to GLSL hacker

200 demos converted now.
List and download link in first post.

Some highlights:
