For other's educational learning or for yours?

Don't know. Maybe I have the urge to leave something here in case some disaster could happen & I can't remember how I did all that mess.

Small clip of the project. Could be cool if other clips from other systems configurations could be "youtubed".

Hi ! Been a while.

Some little fog code taken from different sources.

On gl_rmain.c

Some cvars at the beginning:

cvar_t	*gl_fog;
cvar_t	*gl_fogred;
cvar_t	*gl_foggreen;
cvar_t	*gl_fogblue;
cvar_t	*gl_fogstart;
cvar_t	*gl_fogend;
cvar_t	*gl_fogdensity;
qboolean fog = false;

On R_RenderView function:

Some var at beginning.
vec3_t fogcolors;

then just before R_DrawWorld() call

if (gl_fog->value)
	{			
		glFogi(GL_FOG_MODE, GL_LINEAR);

		fogcolors[0] = gl_fogred->value;
		fogcolors[1] = gl_foggreen->value;
		fogcolors[2] = gl_fogblue->value;

		glFogfv (GL_FOG_COLOR, fogcolors);		
		glFogf (GL_FOG_START, gl_fogstart->value);
		glFogf (GL_FOG_END, gl_fogend->value);
		glFogf (GL_FOG_DENSITY, gl_fogdensity->value);

		qglEnable(GL_FOG);
		fog = true;	
		
	}

	else if (fog)
	{	
		qglDisable(GL_FOG);
		fog = false;
	}

Now we add the new cvars to R_Register function:

 gl_fog = ri.Cvar_Get( "gl_fog","0",0);
	gl_fogstart = ri.Cvar_Get( "gl_fogstart","50.0",0);
	gl_fogend = ri.Cvar_Get( "gl_fogend","800.0",0);
	gl_fogdensity = ri.Cvar_Get( "gl_fogdensity","0.8",0);
	gl_fogred = ri.Cvar_Get( "gl_fogred","0.6",0);
	gl_foggreen = ri.Cvar_Get( "gl_foggreen","0.5",0);
	gl_fogblue = ri.Cvar_Get( "gl_fogblue","0.4",0);

For a good mix with other effects I added some fog check on R_RenderDLights function at gl_light.c file.

  if(fog) qglDisable(GL_FOG);
	qglDepthMask (GL_FALSE);

        ......

        qglDepthMask (GL_TRUE);
	if(fog) qglEnable(GL_FOG);

with an "extern qboolean fog" before that.
That looks good with gl_flashblend 1 enabled.

Nice ;-)

Does it have a software renderer or is it Warp3D only? My setup doesn't currently support Warp3D but I like to try it out (and make a youtube video of it :-D)

[Cowcat]

Yes. ref-soft.dll for RTG.
A video with sonnet stuff ?.....O_o !!

[Hedeon]

OK, Good to know :-)

[Hedeon]

OK, so on soft-renderer with demo1:

320x200 = 32.3 FPS
512x384 = 19.3 FPS
640x480 = 14.3 FPS

Good job with the port. I hope to get Warp3D and such going soon too.

[Cowcat]

Thanks. Still a lot to update/fix to the sources. Even the warpos version I uploaded was compiled without a tailored cpu in mind. So, all of this is left to the readers of this thread (by now).

Anyways, with my run options (exposed earlier), I've got nowadays 12.7-12.9 FPS with 512x384 on Warp3D.......

[Hedeon]

Have to say that I used the compiled binaries for WarpOS (beta2) from this thread. I don't know if you included any optimizations since then? I'm a bit of a noob with compiling C sources. I have vbcc installed, however :-)

Edit: I used the default config file. Except I changed snd_paula to snd_ahi. Oh, and I used a VooDoo3. I might try with the Radeon later today

[Cowcat]

Well, those binaries were compiled from "almost" final vbcc 0.9d (before christmas 2014), so maybe a new compile and some parameters like -cpu (603 or 604) & -merge-constants should increase performance and reduce size (certainly it does). As I said non of those parameters were used for those old uploads, so it´s up to people to tweak to their specifications (minigl lib was compiled with 603 in mind anyways).
Nothing special for soft_dll : Code is mostly untouched from old gcc sources. The last source update has some optimizations to try, but still no new build from me

I'm a bit of a noob with compiling C sources

It's obvious that my abilities are amateurish at most, but certainly Sonnet stuff not !

Quake 2, 640x480, software renderer, on Sonnet:
[ Show youtube player ]

[Cowcat]

Fucking awesome

[Hedeon]

And now with Warp3D with demo1:

320x200 = 45.3 FPS
640x480 = 32.6 FPS
800x600 = 22.0 FPS

[Cowcat]

.....of course everyone expects "the christmas video quake 2 warp3d sonnet " !

Maybe I should upload a new rogue warp3dppc lib that probably works with more cards than Permedia2.......Or more quake2 binaries (difficult to make things just a little better ).

Again, awesome

[Cowcat]

....thinking about the chip-ram issue with sonnet lib. I remember that one of my oldest Blitzquake binary used FastMem instead of ChipRam for mouse code (Indeed it worked, but Frank Wille told me not to do that).

A possible workaround/temporary hack for Paula & mouse ??
Best wishes.

[Hedeon]

All is well through AHI regarding Paula. And I'm guessing in the games I've been playing the mouse is actually being read by 68K code because I haven't seen problems.

Video is on its way :-)

[Cowcat]

Cool!
I should point about "gl_guardband" command that in (some/all?) Voodoo Cards should be enabled for performance. Permedia 2 default is "0".

[Hedeon]

Did what is mentioned in http://www.amiga.org/forums/archive/...hp/t-7150.html (except I use AHI) and it went up to 45.6 FPS for 640x480 and 31.2 for 800x600

[Cowcat]

Some configs are discussed earlier in this thread.

I saw the warp3dppc new video

Just a remainder: The gl versions here don't have the same minigl code as Hyperion Q2, so it's slower compared to that. "ref_gl.dll" for warpos still doesn't do what it's supposed (cleaning textures, etc from time to time) contrary to the m68k version. Don't know about network options as I don't have networked amiga to try & test the code.
Besides of that, It's more stable, has new game options & vbcc fully compatible code & ready for mods since a year

Elbox, where those Sharks went?

Happy New Year.
