[Leaf G. <le...@sm...>]

Just a slight correction to Whitegold's post.  N_PUBLIC and N_DLLCLASS are
the wrong way around. N_PUBLIC class's are exported, not N_DLLCLASS.

Janis,
I have a subclass of n3dnode in a separate package also, but have no
problems including ntexnode.h or nshadernode.h. Could you give us some more
information about what you are doing?

Cheers,
-Leaf.

Most of the nodes in Nebula, even though described as "N_PUBLIC" are not
publicly accessible outside of the DLL they are created in.  If you follow
the N_PUBLIC back to the source, you'll see that it's actually a no-op.
Nodes must be declared "N_DLLCLASS", or the methods desired must be virtual,
to be externally available to other DLL's.

The main reason for this is to reduce the size of the DLL's.  Most people
either end up adding their nodes into the nnebula package (which I don't
like to do) - or they rewrite the class with a N_DLLCLASS tag, increasing
the DLL size.

There are other options available to you to gain access to the methods,
however.  That is what the nCmd system is all about.  You ask the kernel for
a reference, then dispatch commands to it.  Here's a snippet that I use to
create and control my nMatNode:

   nRoot *obj = kernel->New( "nmatnode", "/usr/scene/demo/mat");

   nCmdProto *cmd;
   nCmd *real_cmd;

   cmd = ((nMatNode *)obj)->GetClass()->FindCmdByName("setstate");

   real_cmd = cmd->NewCmd();
   real_cmd->In()->SetS("texture_blend");
   real_cmd->In()->SetS("modulate");
   obj->Dispatch( real_cmd );
   cmd->RelCmd( real_cmd );


There are optimizations you can build into this as well, like caching up the
nCmd's so you don't need to perform a lookup each time and the like.

Hope this helps.

I wonder - are you trying to access their static members, or is this just a
compile-time problem?

Perhaps if you could attach the compiler errors, or a code snippet that
produces the problem - I could be of more help.

    Sincere thanks for the suggestions.

    However, the problem appears when the respective header is #included in
the source. The object is actually never constructed, never called, it
appears only as a declaration in header.

Hi RoboFly -
I have a flat terrain renderer package available on the sourceforge site, as

Hi Tigre -=20

What are the differences between your landscape viewer node and my =
nFlatTerrainNode package?  I'd be interested in seeing what you've done.

If you want to add a package to TND - ask Leaf to put it on the site.  =
This is how my nFlatTerrainNode package was dealt with.  There is =
currently no CVS support, so it must be done this way.

I'm afraid I don't quite understand the vertex question enough to answer =
it for you.

[Nebula-Discuss] Making replies to the list.

[Leaf G. <le...@sm...>]

I just thought I'd let you know that when making replies to this list, you
should use 'reply to all' to send to the whole list and 'reply' if you wish
to reply only to the poster. This is different to a lot of lists, but is
considered 'good practice' (see
http://www.unicom.com/pw/reply-to-harmful.html for some reasons why).

Cheers,
Leaf.

I will post the code for my Truspace exporter when I'm further along.  The
wftools package is a good place to start.  I added another project under
"wftools.dsw" and used the code from the other tools as a reference.  I #include
wftoolbox.h and wftools.h.  I create a new wfObject and as I parse the Truspace
file (it's ASCII, which makes it easier) I just fill up the v_array, vt_array,
and f_array with vertex, texture, and face data.  Then I send the object through
clean(), smooth(), triangulate(), and flatten().  Finally I tell the resulting
object to save itself and clean up the memory.


Hope this helps,

-Aaron

Re: [Nebula-Discuss] Hello? Anyone there? (Python)

[Inquisitor <my...@fo...>]

I'd be very interested in seeing what you accomplish with adding lua to the
Nebula Device. Are you thinking about adding version 3.2 or 4.0? 4.0 is
still beta right?

Also, I'm going to start working on a model exporter for Cinema4D sometime
soon. I'm not sure if anyone on this list uses Cinema4D though. It seems
like a lot of people are writing exporters individually, do you all think we
should try to work together on the exporters or at least post general
info/tips about writing exporters to help each other out?

BTW, I'll post any updates, bug fixes, add-ons, etc that anyone has for TND
on GameDeveloper.net. And if you have any information about using TND or any
How To's that you would like to share I can post that too. You can monitor
the postings in gamedeveloper.net's nebula device message board through
email too, so even if you don't use the board you can still register and
watch for new posts through email.

Hi -
Not dead in the least - we're all just so busy working on our own projects
that we sometimes forget to say HI!

I'm putting together a 2nd version of the Maya exporter for Nebula.  It
includes geometry export as well as animation export this time.

Luck to you all!

Re: [Nebula-Discuss] Hello? Anyone there? (Python)

[charlie w. <ch...@3d...>]

i've been looking at adding lua to it instead of tcl/tk so i'll be
interested in what you see.

i fixed a few small bugs, mainly in the error handling routines,
should probably post them to sourceforge but the it seemed
dead.

Re: [Nebula-Discuss] Hello? Anyone there? (Python)

[Ben S. <be...@ni...>]

Likewise, I have been on it a few weeks and haven't seen anything.  Email is
less irritating for me to manage than the sourceforge discussions.  It's cool
that someone is working on 3ds stuff, I work in linux primarily without tools
like 3ds or Wavefront, so I'd really like to see DXF support.  

Right now I'm working on embedding a python interpreter server into TND.  After
that, it may make sense to make python language bindings around the different 
modules of nebula to control them that way.  What I'd really like to do is be 
able to subclass any of the c/c++ implemented classes that come with nebula 
with python classes and use them transparently by TND(probably with some help
of the python ExtensionClass).  Based on what I've read of TND's docs, the 
scripting server component translates a few language commands to TND Command 
objects, but I'm not 100% sure as I don't know tcl and I don't wish to learn 
it.  It was also suggested by the docs that translating to TND command objects
is the way to do it for "generic" script interface support, but that language
bindings would also be desirable.  That's all if I understand what's going on 
correctly.  I'd appreciate comments and suggestions and help and not flames.

I was utterly blown away by the tekdemos, as were many of my friends.  TND 
looks very much like something I was planning on writing, though fortunately 
now I don't have to :)  Thanks!  It's awesome!  I hope on hacking on it 
mightily.   =)  The licensing is also very nice.

[Nebula-Discuss] Hello? Anyone there? (TrueSpace converter)

[Aaron C. <aa...@or...>]

Hi,

   I signed up to this mailing list over a week ago, and havn't gotten
one message yet.  Is something wrong, or is this just a really quiet
list??

   Just in case someone's out there:  I dicovered TND a couple of weeks
ago, and I am very impressed!  I am now working on a converter for
TrueSpace.  I have the geometry translation done, and am now working on
materials/textures.  Hopefully someday it will also do animation.  It
reads a TS scene file, and outputs several mesh files (.n3d) and a TCL
script to load them into TND.  I'll let you know how it goes.

[Nebula-Discuss] Sample Game development

[Nathan H. <hea...@ho...>]

As one who is new to the Nebula Device, but not new to 3d, game engines, or 
programming (TCL included), I'm curious to see if anyone has any working 
game examples. I'd like to use TND to make some simple 3d games, but I think 
I need some more complete and/or verbose examples of a functioning game that 
uses TND.

Is anyone working on any personal projects that they'd like to share? On the 
flip-side, is anyone working on projects that they're looking for help with? 
My skills run strongly towards the 3d end, with followed up by TCL 
abilities...my C++ skills run a distant third.

[Nebula-Discuss] Linker problems

[Janis S. <jan...@na...>]

Hello everybody,

Has someone encountered linker errors in the last version of Nebula? It =
affects nTexNode and nShaderNode particulary. The linker throws the =
usual "symbol not found" errors, though the libraries are all included, =
and the classes are exported. Tried to change N_DLLCLASS and N_PUBLIC =
macros, but nothing helped. The strangest thing is, that these errors =
appear on "random basis", almost on every third full build of the =
engine. By the way, the old Nebula version compiles OK with the same =
additional code (with nShaderNode removed, of course).
Maybe that's MSVC bug? Any ideas?

[Nebula-Discuss] patches for Linux & gcc2.95.2 compilation

[Vaclav S. <v.s...@vo...>]

Hi,

attached you can find a patch (3kB) that fixes some compilation=20
problems, namely:

- gcc 2.95.2 cannot implicitly convert from int to GLenum in couple  =20
  of places
- wftools makefiles didn't link to math library=20
- #including "gfx/glxext.h" caused tons of unknown identifiers and=20
has proven as unneccessary in combination with Mesa. (Fix for this=20
one is at the very beginning of the patch, so you can easily remove=20
it if you don't like it.)=20

The platform is: Linux 2.2.12, gcc 2.95.2, OpenGL library is Mesa 3.2=20
(compiled as software renderer).

Regards,
Vaclav=00

[Nebula-Discuss] NArgs Bug.....

[Matthew G. <ma...@da...>]

Hi all,
	Has anyone encountered the nargs mem leak.
This is the output I am getting.

size = 6
src  = c\kernel\narg.h
line = 138

inline void nArg::SetS(const char *s)
{
> n_assert((ARGTYPE_VOID==this->type)||(ARGTYPE_STRING==this->type));

The other suspect here I am guessing could be TCL with WIN2K?! As this is
the only other lib in the mix. Any similar experiances out there?

The bug seems to be intermitant, in some builds I have had Nlaunch crash a
few seconds after console launch (while typeing) and in others it has taken
a large file to do it.

The size seems to vary but the line is always the same. I am building using
WIN2k and I am using both MSVC 6(service 4) and the Intel 4.5 compiler.

The problem is this is so intermitant I am having trouble knowing where to
look (while translating German comments :) ).


I have been building the new release which looks very promising by the way.

I am particularly impressed with your approach to the scene graph and vertex
clustering (I was working on the same approach myself when your update
turned up). This realy does open the flood gates for decent clustered
animation. I am using Maya and have found the only satisfactory solution to
the problem of using models with complex changeing layered structures is
Smooth Skin clustering.

Question on Memory Management; The nebula uses wrappers for memory
management, Has anyone experimented with different allocation calls? Am I
being paranoid or are there still operating system issues causing problems
here?

By the way I have translated much of the origional code comments with a
purchased version of the online Bablefish translation tool, which is
amazingly good for what it is. I would like to contribute this to the Nebula
project at some point but the question is how best to integrate it.
Your scripts read from the source files I think. Any suggestions? I could
package them into a new doc but this will take a little while as time is
short for me at the mo.


Cheers

[Nebula-Discuss] Sound problems in Nebula

[Leaf G. <le...@sm...>]

Hello,

first, regarding the mailing list, I may have not set things up in the best
way, so if you have any problems or any preferences, get in touch.

Ok, I have a problem with the sound in Nebula. I can get a nsoundnode to
load and play a sample but it only plays the start of the sample, it seems
that every frame it starts the sample from the beginning. If I slow the
frame rate down then I can hear a little more of the sample, if I let it run
full speed, I just get car engine fx 8)
I've done _some_ debugging and it appears to be loading all of the sample
and correctly identifying the length, but not playing it. So before I go any
further, is this just me and my system, or something that effects other
people too?

Cheers
-Leaf.

p.s I'm using win2k/win98 sblive.

[Nebula-Discuss] Welcome

[Leaf G. <le...@sm...>]

Ok, so we have a mailing list. It's all shiny new and empty at the moment,
so let's try and keep it that way ;)

I may have not set this up right, so if you have any problems or ideas about
how it should be setup, please tell me.

Cheers,
-Leaf.
