Just hoping to arouse some interest from the programming wizards:

Looks pretty cool, may be usable on our precious-but-matured polygonpushers as ships don't require super-high framerates

It's done in Scons though, i vaguely remember Jarndyce muttering about that while compiling Blender

Hi,
It seems like an interesting game.

I don't know scons or GL, but I've managed to hack it enough that it compiles (patch below). It doesn't link (errors below) and I somehow think this was a bit too easy (there are lots of warnings too, most of which I disabled). scons does some strange things, but it does finish eventually. Running it a second time (after it fails) shows the command used to link (which needs -lm added to it).
Linking fails with the following symbols undefined: fftw_execute (which is in /usr/nekoware/lib/libfftw* but those don't get linked for some reason), glActiveTexture, fftw_plan_dft_c2r_2d, fftw_destroy_plan, glBindProgramARB, glProgramLocalParameter4fARB, glLockArraysEXT, glUnlockArraysEXT, glClientActiveTexture, glGenProgramsARB, glProgramStringARB, glGetProgramivARB, glDeleteProgramsARB.
That's after adding -lm manually. Anyone know what these symbols are and if they're usable on IRIX? Google didn't seem to be of much help (although I didn't search for all of them). I think the fftw things shouldn't be too hard to fix, but I don't know what to do with the gl ones.
Patch 5329 may be needed (it was for me).

This is also at http://rafb.net/p/RRqjNE41.html but that will expire after 24 hours. That should work if copying the following doesn't apply cleanly.

Linking fails with the following symbols undefined: fftw_execute (which is in /usr/nekoware/lib/libfftw* but those don't get linked for some reason),

dangerdeep 0.2 uses libfftw 3.1 while nekoware is at 3.0.1. This could be the problem here.

These are all calls to OpenGL that deal with newer type of extensions like GLSL etc. If these calls are used directly within the code it is very bad style, typically you query those as function pointers and use them only if they are defined.

Thanks - that seems to work okay. Linking to a static libfftw 3.1 fixes the two fftw symbols.

(edited: I fixed the patch so it really does apply cleanly now :oops:

)
I #ifdef'ed out all references to the undefined GL symbols, and the game runs now. Sound/title screen/etc seem fine. Viewing vessels works, although some of them are simple white models (the #ifdef probably broke them).
It seems to play missions now, although I don't know how to do anything. :oops:

The new patch (includes the previous ones, so this is the only one needed) is larger. It's at http://www.nekochan.net/wiki/ ... deep.patch which seems to apply cleanly. The link line needs to be manually modified again - I removed the -lfftw3 and added -lm and ../fftw-3.1.2/.libs/libfftw3.a to link a static version of fftw-3.1.2.
Performance is almost passable for me (Fuel/500/V10). The scons file says that it should be linked against an --enable-float build of fftw for performance which I haven't done yet.
I'm really off to bed now, but thanks again.

Let's see what's missing in detail:

glActiveTexture, glClientActiveTexture
These functions select the active texture unit for the multitexturing interface in OpenGL 1.3 IIRC (promoted from extension GL_ARB_multitexture). This is not available in any MIPS-based SGI system, you would have to rewrite the rendering to use multiple passes, one for each texture with the appropriate blending modes between the passes, in order to work correctly (if it's not used exclusively with GLSL programs see bellow).

glLockArraysEXT, glUnlockArraysEXT
This comes from GL_EXT_compiled_vertex_array, which isn't there on my VPro octane2, there is a EXT_vertex_arrays, which could be used instead I guess. Personally I haven't used either one of those, the standard these days is ARB_vertex_buffer_object (which isn't supported either).
If EXT_vertex_arrays proved inadequate or not supported on older sgi systems, you could rewrite the relevant parts to use immediate mode (glBegin/glEnd) but expect a significant performance drop. If the arrays are not modified too much your best bet would be to rewrite the code to use display lists which is a standard OpenGL 1.0 feature.

glBindProgramARB, glProgramLocalParameter4fARB, glGenProgramsARB, glProgramStringARB, glGetProgramivARB, glDeleteProgramsARB
All the above are part of the GLSL (OpenGL Shading Language) interface, as defined through the extensions ARB_shader_objects, ARB_fragment_shader, ARB_vertex_shader. (the actual OpenGL 2.0 interface for these is slightly different and does not include the ARB suffixes of course). There is absolutely no way you can approximate the shader-based rendering in a MIPS-based SGI. Only one common usage of shaders (per-pixel lighting with vertex-interpolated normals) can be done with VPro systems using the SGIX_fragment_lighting extension. But most games which use shaders for per-pixel lighting also generally modify the normals inside the shader or derive them from normal maps, neither of which can be approximated without shaders.

Your best bet is to check out if there are compile or run time switches that disable the use of shaders and multitexturing in the aforementioned game, otherwise you have a lot of rewriting to do :)

Wow, thanks for the details.

Unfortunately I'm really not capable of rewriting the rendering :wink:

, but there are a couple of configuration variables that can be changed. I have the following in ~/.dangerdeep/config (created the first time that dangerdeep is run):

Code: Select all


<use_shaders value="false" />


<use_shaders_for_water value="false" />


<usex86sse value="false" />

These are referenced in the code, but I haven't really read enough to make sure they're always used. But, with the patch linked above it seems basically playable. Pounding on the keyboard gets me "Crash dive!" "Engines ahead flank" and the like and then the bridge view becomes dark.

(edit: I also put a binary with -O3 -mips4 -n32 at http://skipfiles.googlepages.com/dangerdeep2 as that fixes the issues with other subs/etc. But, it's noticeably slower. So that one works a bit better, but the next one is faster. 6268K)
I compiled a binary using the patch from before with -Ofast=ip27 -mips4 -n32 and put it at http://skipfiles.googlepages.com/dangerdeep if anyone would like to try it. It's 6036K.
It requires SDL, SDL_image, SDL_net, SDL_mixer, libiconv, libpng, libjpeg, libtiff, libz, libvorbisfile, libvorbis and libogg from Nekoware. It also requires the 0.2.0 data files from http://www.dangerdeep.net in the default location (/usr/local/share/dangerdeep). I -think- the binary is sufficient, everything required should be linked statically, but I only have a single machine to test on.

Performance is better (than the -O3 build) for me. Some things are broken, but the training missions (in historical missions), and I think all convoy battles with the VIIC (the first) sub seem to basically work. The other subs worked before, but somehow I broke them I guess. Destroyers are rather dangerous, but it's possible to hide. Some ships have become invisible and/or invincible.

I'd love to hear if it doesn't work at all, or if it does. Some textures look a bit odd, but morning and evening are pretty.

Anyways, happy New Year everyone (in 3 hours here

)

Hey, thanksalot. It works here on fuel v10. I had no luck with your patch (-lm needs to be in last place, how to do that with scons??).

funny:

Happy new year! Still 5hrs here...(central europe).

I don't know how to use scons, but I run it once, wait for linking to fail, then run it again. The second time it shows the command used to link (with -lm at the start). I copy and paste that, removing -lfftw3 and adding "-lm ../fftw-3.1.2/.libs/libfftw3.a" to the end. I really need to patch SConstruct properly at some point.
I'm really glad to hear that it works.

Haha - that is funny. I wonder if it's broken in 0.2.0 in general, or only on IRIX. Thanks for trying it.

Well, this sure generated some interest

Performance is almost passable for me (Fuel/500/V10).

Ouch! I was hoping lumbering boats wouldn't tax the system so much; apparently there's a lot of heavy stuff going on behind the scene...my Octane's gonna have a tough time with this

I built dangerdeep on linux a while back. 50% of the game wasn't implemented yet, and the other half crashed if you dared to sneeze. Has it improved since then? I could use another game on my Octane...

thanks for the work, but both executable crash on my octane2 (r12k and r14k)

i have the main mene, mission choice, but after had loaded the mission, it crash

It's playable for me, really it's only the periscope, bridge, free 3d and UZO views that are a bit less smooth. The lead developer wrote on their forums:

System requirements in general: 1.0GhZ+ better 1.5Ghz, 256mb+ better more, a modern graphic card (DX8 or OpenGL 1.4 with shaders).

So I guess it's a bit intense.

Alver wrote: Has it improved since then?

This is the first time I've tried it - 50% of the game still isn't implemented, but the implemented half seems stable for me (in the -O3 build I linked). I haven't tried any of the official releases, but the biggest issue for me is that whacking the unsupported extensions without adding anything makes the game somewhat less pretty than the screenshots. That and I still haven't hit a moving target with a torpedo. :wink:

Sorry about that.

I don't really know what would cause that (and I don't have an Octane unfortunately, they seem a bit uncommon on the secondhand market near me). When you start the mission, there should be another initialization screen (white text on black, like the startup one). If you get that far, what is the last line it shows?
lhaza posted that it worked for him, but I have the same hardware. Anyone have ideas?
There is an error posted on their forums about the Windows build (but is probably in all the builds) here that has a "Caught exception: St9bad_alloc" at startup (not mission loading) when the data files aren't installed. The data files are installed in the proper spot? (/usr/local/share/dangerdeep/convoys should exist)

Hm, it works here on Octane2 V6, r12k, IRIX 6.5.22. I tried the historical mission, one or 3-ship convoys. I have never hit a ship though...but diving etc. works.
I have put a tar.bz2 with the data at http://lhaza.com/ditd/dangerdeep-0.2-ir ... ta.tar.bz2
It is ca. 53 MB :shock:

(edit: it was 105 MB including the data-zip)
run tar xvf dangerdeep-0.2-irix6-mips4.withdata.tar.bz2 as root to etract to /usr/local

It needs neko_sdl*

dangerdeep logs the fps...

the scenes around 9 fps (fuel) / 5 fps(octane2) are the freeview or telescope-views, I guess the water brings them down. (I think have seen much faster and even nicer ogl-water-simulations in pre-shader-times ...)
However one has to do alot aside from these views, it is fun to hunt and bring down BRTs...
the views were just randomly chosen....
