Perhaps can also install old StormMesa for 68k 3D games to run on OS4
But I am not sure if they would run anyway on OS4...

CompositeTags() can use Amiga's "bitmap" as output and also as input (=textures) that give it more flexibility than Warp3D/OpenGL

Also it is more simple to draw with this single function than to setup Gallium3D/Nova thant need (say) 50 functions before even draw something

CompositeTags works in hardware on all my NG machines : Sam440,Sam460,X5000

IMHO The main point of CompositeTags is to draw blits with scale/rotation/transparency/filtering = same as SDL2 or Cairo but in a single/simple function

I am no more coding: I dont have time to do coding

@Maijestro

You are right bad colors in 15/16 bits mode are allways due to unknown pixel format
Lots of pixel formats are defined in Wazp3D but some "not really" Amiga apps (or OSes like Aros) may use unknown ones

@kas1e
Thanks for feedback but I didnt code for months...
Bug1) seems normal to me : act like two mirrors facing so works as expected
2) I know the bug but the cause is unknown: seems the os mask the icons somehow ...
3) works for me: certainly one of yours windows is "special" and cant be grabbed
4) some msg are copied well but some are missing : I dont know enough amigaos to find the fix
5) i know but dont know how to fix
6) i didnt knew but ditto
7) ditto

>shadow in wipeout2097

Is a bug in wipeout2097: bad parameters for a warp3d fonction = only works for old badly written warp3d drivers that dont understand the parameters = not a warp3d bug

There is an env-var parameter to patch this

Perhaps is it possible to add some kinda "include" to the shaders : a text file containing all (Nova) missing fonctions like min(), noise(), etc.. defined as macros
This "include" then just need to be concatenated with the shader
macro.txt + shader.frag = tmp.frag
Then compile/use tmp.frag

I also made a waZp3d with an hardware Nova renderer
So can help for machines without WaRp3d drivers
Sadly it is very slow with minigl apps (cause unknown...) son was never released

Does those shaders works if those unintialized vars are set manually ?
( I mean edit the shader)

Hello
Perhaps using the same texsampler for all textures may economize some registers as each texture units use several registers

I mean if all textures are (say) linear then juste create one texsampler and use it for all textures (vs creating a texsampler each time we create a texture)

There was the same problem with blender/wazp3d
Was long ago but I remember blender need "direct to bitmap" drawing and "no indirect mode" = I mean each menu is fully drawn then next menu, so need a "flush" after each "drawprimitive"
Looks like menu drawing in blender is poorly coded and should have included a kinda "flush" for this drawing operation

Almost OT remarks: but you can rotate a window with my aminet/clonewindow

As Nova can use bitmaps as source and dest it may be used to accelerate things too.
But Nova is so hard to setup even for basic drawings...

@SinanSam460

Certainly a SPE version wont change speed as it is certainly only the GPU that do all the computation in the frag shader "program"

>much better than Wazp3d with nova rendering which in general never works (see comments from Mufa, and his tests on amigaone.pl)

I just read Mufa comments:
WipeOut2097 got several problems as an old warpos program it need something like rewarp for warpos emulation, a Warp3DPPC.library, got a bug in ChromaTest, etc... so making it works 100% correct is a real problem on any configuration (Warp3D or Wazp3D)

Wazp3D57nova works for some programs: if it never never works for some people then they dont use or installed it well
But I agree it is too slow (for an unknown cause) so unusable for big programs ...
I have tried several optimisations but look like something "block" Nova to draw at maximum speed ... it was a big deception and I never touched this code again... so Wazp3D57nova was never officially released
http://thellier.free.fr/Wazp3D57c.zip

But now MiniGL4GL4ES exists and it is much better

If OpenGl used compositing in some cases it will need to have the texs in both formats: GL texture + Amiga bitmap

Hello

The better solution is to let gcc do the works for you
I mean: put the function to optimise in separate file say "myfunction.c" then ask gcc to compile to asm with -S option you will obtain a myfunction.s that you can edit to optimise the code
then build/link the project with this modified myfunction.s
as source

1)
gcc -c main.c
gcc -S myfunction.c
2)
edit myfunction.s to myfunction-optimized.s
3)
gcc -c myfunction-optimized.s -o myfunction.o
gcc -o myprog main.o myfunction.o

Hi kas1e and Happy New Year 2020
(Even if we are still in 2019 here at Paris)
Is there any davantage to use this minigl wrapper against Wazp3d 57 with nova rendering ?
I mean both solutions allows 3d cards with only a nova driver to run minigl apps...
