Mesa Showcase Demo for AmigaOS4.1

Hey all,

wanted to share a little demoscene showcase I put together, running fully native on AmigaOS4.1 — video and audio, no emulator, nothing borrowed. Six GLSL ES 3.00 shader scenes with crossfades, a beat pulse, and a scrolling credit, all going straight through mesa.library.

None of this would be possible without kas1e's Mesa port. Reverse-engineering the RadeonRX/RadeonHD drivers and getting real hardware-accelerated OpenGL working on this platform is a massive amount of work, done for free. This demo is just a small "look what we can do now." Thank you, kas1e!

Planning to put it up on OS4Depot soon. Happy to answer questions in the meantime.

Nice! Thanks for taking time and doing the showcase!

Btw on showcasing i am looking into porting
OpenMW (morrowind!!!) and penumbra:overture
to os4 mesa.

Openmw nearly compiles though till it runs still
a lot to do. Endianness etc. (Have access to some
Endian adaptions of older Version not on the net).
My port will be based on 0.47 for technical reasons, not
0.51.

On penumbra some work on a required closedsource lib
To do but i have a good contact there which should fix
the issue ;)

Note - openmw will pretty sure be x1000 minimum (i hope
x1000 enough, x5000 should be safe), penumbra
probably x1000 plus pretty save, maybe Sam 460
(Sam pretty unsure).

Assume os4 exclusive (aros x64 might be possible),
Warpos, morphos and 68k (not even pistorm3d) impossible.

These two are possibly the most demanding ports ever
tried on AmigaOS.

I know i recently was a bit 68k focused. This will be
(Besides a possible unnamed commercial project) my
new projects for os4 - bring os4 to a new level. We will
see if it works but i am confident (and currently between jobs).
And yeah i also looked into gemrb 0.9.5 but morrowind and
Penumbra get higher priority. I was just waiting for mesa
for this, have been looking into those sources and their
Dependencies for ages ;)

For 68k people i will have gemrb 68k and some new
Pistorm3d based games ;)

It is not a showcase but GLFW now is using Mesa!

@Maijestro

It ran perfectly on the A1222 with a weak RX550! It was nice to see :)

Hello,

It crashes at startup here on my X1000.

KR

Crashes on X1000 here too.

No problem on Sam460 except from some crackles in sound.

Yupp here also on x1000 Crash.
Crashlog in os4depot.

@TearsOfMe @Petrol

Turns out the demo was built with X5000-specific compiler flags by mistake, which don't work on the X1000's CPU (different PowerPC variant) — that's what caused the crash. Rebuilt with more generic flags that should work fine on both. Updated binary is up.

Also — thanks a lot for the crash logs, they really helped pin this down fast!

@Maijestro
New Version works here on X1000. Thank you.

@Maijestro

Very cool!

@all

I wonder if HunoPPC knows about this new mesa.library?

He has done two very heavy ports to AmigaOS 4.x, Doom 3 and Prey.

@Maijestro

Tested on my sam460ex and works great!!!

New version perfect on X1000, thanks.

Mygui (based on mesa) runs now. First step towards openmw.
Next step will be openscenegraph (links already, working on
Demo program).
