software OS4   software OS4 : ShaderJoy 1.8 for AmigaOS4 released
   posted by kas1e on 1-Jun-2020 6:56:22 (1387 reads)
ShaderJoy is a tool that can visualize GLSL-based fragment shaders written by Capehill (Juha Niemimaki). The goal is to have some compatibility with Shadertoy database: https://www.shadertoy.com/

(click on image for fullsize):



Download latest version from Capehill's page: http://capehill.kapsi.fi/shaderjoy/Shaderjoy-1.8.lha



Latest Warp3DNova and OGLES2 need it, which means, in turn, RadeonHD or Radeon RX as well.

Version 1.8 featured:

- Support of many ShaderToy's uniforms, such as iChannel0...3 textures, iChannelResolution0...3, iTimeDelta, and iFrameRate uniforms, iDate, iMouse.y and others
- Use vertex buffer objects (VBOs).
- AppWindow support: shaders can be dropped into the window.
- Verbose logger
- User-selectable VSYNC mode (WaitTOF, WaitBOVP, or disabled).
- Display running time on the window title bar.
- Fullscreen support
- Tooltypes
- It can be set up to be used via DefIcons, so double-click from Workbench/Filler/Dopus/etc works.

Wow, very cool demo and screen grab.

What kind of system hardware is required to run the software?

An OS4-compatible system with a graphic card supported by Warp3D Nova.

Video recorded on my x5000 with Radeon RX 11 2gb. RadeonHD fits too, of course, just need to be "fast one" for complex shaders to works fast.

In other words, sam460, x1000, or x5000 are necessary with good RadeonHD or Radeon RX. I.e. things where Warp3DNova and OGLES2 works acceptably :)

So this is... a game? A developer tool? A demo? Something else?

Here's an idea - spend a minute or two to describe what the software is supposed to do, who should use it and why they should use it. It's basic marketing without preaching to the choir.

There is another idea, you read what is written in the first post: " ShaderJoy is a tool that can visualize GLSL-based fragment shaders", then, using google if you know nothing about. And even without google trying to understand what means "tool that can visualize".

Don't be a petah1200.

It's...complicated :)

Maybe the main purpose is to enjoy digital art: those amazing shader programs created by genius people.

But it also has its practical uses, for example it could be used to prototype shaders used in a game or demo.

Thirdly it can be used to test Warp3D Nova shader compiler compatibility.

So I tried it out on my X1000. In the default window I was getting a respectable figure close to 60FPS. Then I tried a full HD screen. Speed dropped to 15. Tested a few others and it went down to almost 2. Dissappointed in my R7 250 now. But it was strange. Such as the Amiga boing scrolling pattern. Didn't think scrolling a 2d texture with alpha transparency would need so much CPU and GPU power. Full 3d will kill it.

If you want to benchmark, then disable VSYNC. I suspect you did not disable it, because here, on 1920*1200 resolution, "amigaaa.frag" runs at 300+ FPS.

Feel free to test the same shaders on Shadertoy.com and report back :)

I didn't have it disabled as I prefer the VSYNC being on. Plus I was using the default settings. I wasn't sure why the initial blue screen had an FPS wavering as I expected a blue screen doing nothing to be infinite FPS.

So in a window the "amigaaa.frag" got me 750 FPS on average. Full screen 1920x1080 got 140 FPS. Better than 15. Just under half your 300 on a bigger screen.

Total noob gave 105, celular 60, fire 18, kissing nipples 1.5 and as I expected; the road to hell, despite being lined with gold and more nipples, gave me a whopping low 1.2.

Also, why are they called frags, are they a development of Quake 2?

I have an R9 270X, that possibly explains the speed difference.

Khronos is using .frag suffix for fragment shaders ( https://www.khronos.org/opengles/sdk/tools/Reference-Compiler/ ) but there is no other reason for "frags".

Ps. blue screen is generated by default.frag. It can be replaced or modified as desired.

An R9 would explain a speed difference I expect. But right now, they are also hard to find new, and likely still expensive. An RX is desirable. But out of reach for X1000 owners.
