Can't wait for a stable version of v2 so I can make some apps with sprite shaders!!
This looks very cool.

Really freakin cool Jukuma, and with source code to boot!.

Between this to play with and Swiss's Poly fill routines, I feel like its Coding Christmas in the AppGameKit home tonight.

Decorate those imaginary tree's and put another log on the fire.

Thanks Jukuma and as I stated before, all code given to the forums is greatly appreciated.

I love tinkering with other peoples programs and seeing what I can add and find.

Peace out and thanks again!

what is the pixel.ps file?
Although the PSP6 doesn't refuses to open the file, I see nothing
Really it is a very cool demo!

That is just incredible. Any chance of a tutorial on that shader?

I played with shader toy ages ago, but never thought it could be brought to AppGameKit like this..

Wow. Impressive stuff indeed.

It's the pixel shader file. It's just a text file and you can open it in notepad.

All Shader from Shadertoy works on AGK.

This is very cool.

When I first saw it, I didn't realise that the image itself was generated by the shader.

I've only had a quick play with Shadertoy, I must really give it a closer look.

To use a Shader from Shadertoy you must change the uniform of
samplerxx in the right GLSL Sampler.

Thanks Ranietz but could someone give some basic information because I don't know many about shaders.
Where are these colourfull graphics? the sun, the rainbow etc

I have not looked at the project/shader files but I assume all the graphics are created by the pixel shader. I've tried to learn about shaders myself but it's hard to find much info for a beginner like me and shaders on sites like shadertoy is usually not commented very much.

Also, I feel that the shaders from shadertoy is more a demonstration of clever coding skill and use of algorithms and I don't think they are that usefull for game programming. But they are impressive.

And it would be very helpfull if someone could make a tutorial for using shaders in AGK.

@Jukuma I have awarded you an AppGameKit Master and Valued Member set of badges for all the great shader demos you have made over the many years you have been involved with the community.

This morning I have made a video of some of the shader demos you made in AppGameKit and this video will be one we will show on STEAM to show that AppGameKit can handle these effects.

So thanks for all you have done so far and we hope to see more cool demos from you soon.

Cool! Where can we see the Video Rick? My PC is too slow to render this shader properly (it works, but I get like 1 frame per second!).

Great stuff Jukuma, and congrats on the badges!

Hi

I have tried some cool shaders (from shadertoy), with the demo of Jukama.

1) Blob

This Pixel shader works great with the demo of Jukuma (name : blob.ps):
+ Code Snippet

Just change the line in the code :
+ Code Snippet


2) Fire ball

Shader (fireball.ps):
+ Code Snippet

Just change the line in the code :
+ Code Snippet

3)Seascape

Shader (seascape.ps)
+ Code Snippet
