Hi Benoit,

According to your suggestions, I write via devel list.

Done. My sourceforge account is "tommyline". Do you need any more info?

This is the biggest question mark. 
1. I've noticesd some changes in commiting to subversion, but didn't put much attention to it, have to check archive for guidance, but I don't know how to operate on branches (or how to create ny own directory there). Would be gratefull for some advice.
2. If I wanted to add some opengl subcomponent (GLFW for instance), how can I do it properly?
3. I was thinking of md2model as a part of a game engine, so I tink it would be named as something like gb.sge (simple game engine - particle system to follow, rigid body to be developed etc.). Do you think it would be ok to create that component? 

>3) Apparently, your class can only be created by calling the Load()

Corrected.

Corrected too.

Comments in class files, I can do that, but could you explain how to add documentation pages about new methods in new classes?

That's for the moment.

Hi Benoit,

I was able to make new component and compile it, but can't test it. It's grey in component list as all experimental components, but IDE calls "component not found gb.sge". It doesn't show in reconf-all or configure too. I don't know what I do wrong, it seems not registered by Gambas. I attach .conf file from TEMPLATE dir.

Thanks
Tomek Kolodziejczyk.

Of course, the template just creates the directory and some files. But 
all the autoconf/automake files must be modified by hand.

Do you know how to use autoconf and automake?

I was hoping it would be as easy as adding directory names to makefile.am and configure.ac but it didn't quite work, so I need help.

That's it.

You must update the SUBDIRS variable in the root Makefile.am with the 
new component directory, and add a new GB_CONFIG_SUBDIR() macro to the 
'configure.ac' file. Then you run "./reconf-all".

Look at the two top-level files:

- Makefile.am: Add your @sge_dir@ line to SUBDIRS
- configure.ac: Add your GB_CONFIG_SUBDIRS line

Then

$ ./reconf-all && ./configure && make
# make install

But how did you make it show up in the IDE dialogs without installing it
properly?

Tobi

You must use "svn add" to insert new files or directories into the 
repository. *BUT* do not insert files that must not be inserted!

In other words, do a "make clean" into "gb.sge" before adding it.

By the way, as this is an OpenGL thing that depends on OpenGL, you must 
rename your component into "gb.opengl.sge"!

If I change the name now, all I have to do is to change it in main makefile.am and configure.ac or make it from the begining? What will happen with the gb.sge I've already commited?

@Tomek Sorry to interject into the thread so rudely, but I'd like to say 
thanks for giving this some attention. With the coming of Valve's 
"Steambox" and the native Linux Steam client I think it's only a matter 
of time before GAMBAS proves itself a worthy language (with respect to 
compatible/available market share) for game development. Awesome effort 
and I'm proud of everyone here helping you jump the technical hurdles of 
implementing your component.

Thank you, Kevin, it's very kind of you.
Did you try Md2Model example? Could you tell me your FPS rate and GPU 
you're using? The same question applies to everyone that tries it.

Thanks,

Yes thank you.  We have some work done in the svn
Gb.g3d... take a look in the exp branche. It is based on ogre. And have
stuff done to load mesh in gambas archive.

Take a look to blitzbasic and blitz3d for implementation ideas. But do not

Hi Fabien,
What I had in mind when started writing this, was pure simplicity, which 
means every class is independent of the world and can be used on its 
own. I tried Ogre, Ode, Irrlicht, and all of them seemed quite 
complicated to use. And I didn't know about your effort just until some 
few days ago. Is there any example of how to use gb.g3d engine?
I have particle system implemented too, I will commit it as soon I'll 
update the names to match Benoit's syntax.

Thank you
Tomek Kolodziejczyk.

I didn't say you must use engine such as ogre an independent one is better
but long to do.

Just keep in mind that the most of the game rendering and scene calculating
must be done by your class...  in C or c++

Hi Tommy,

Beware that you don't write your subversion log correctly. Only the 
r5590 was written with the right format.

If you don't use the right format, I can't generate the changelog 
automatically from subversion log, and I have to fix it by hand, which 
is quite time consuming.

If the log format is not clear for you, just tell me and I will explain 
it again.

Regards,

Hi,
I had some issues with svn complaining about not filled info but I 
passed it only once as I remember. Could you show me what was wrong? And 
if you can, please explain how should I do it.

Thanks,
Tommy.

Good (r5590) :

[GB.SGE]
* NEW: New experimental component for simple OpenGL gaming engine.
* NEW: Md2Model loader and renderer.

[EXAMPLES]
* NEW: Example to show how to use new Md2Model component.

Bad (r5591) :

[GB.SGE]
* BUG Forgot to add files

[EXAMPLES]
* BUG Frogot to add...

--> The ':' character after "BUG" is missing.

Bad (r5594) :

[GB.XML.HTML]
* BUG: Does not crash anymore if the id or class properties does not 
exist when reading them.

--> The line it too long. The length must be lower or equal than 76 
characters.

[GB.OPENGL]
* NEW Added some new constants

--> The ':' character after "NEW" is missing.

Bad (r5594) :

[EXAMPLES]
*OPT Minor update to Md2Model Example

--> There is a missing space before "OPT", and a missing ':' character 
after.

You should define the EDITOR environment variable in your 'bashrc' file 
with the editor that will be used to enter the svn commit log.

For example:

$ cat ~/.bashrc
...
export EDITOR=kwrite
$

Thank you Benoit, I didn't know the space was so important, and the : 
sign is my mistake, sorry.
The strange thing was that svn was complaining AFTER i finished and 
saved the file in pluma (mint 13's gedit). But it was ok after i 
restarted computer, so it could be some bug in system.

I've try the example :-)... it work well ... 60 fps on my machine.

I think you must to embed the init process in the screen class, to simplify
the user work.


ogre as new md2mesh

ogre.loadtexture("path")

ogre.addsequence("walk",0,100, 5000)  (seqname, firstframe, lastframe,
duration of the sequence in ms)


public sub key_press
if key.code = key.up then
    ogre.move(x,y,z)
   ogre.sequence = ogre["walk"]
   ogre.start
  endif

end


public sub screendraw

  ogre.draw

endif


an internal timer increase the frame and the interpolation .

but we can imagine also some way to force on a choosen sequence frame

ogre.stop
ogre.frame=3


well this is just some ideas to simplify the api but not the better way lol
it's just matter to think

the opengl class must have to be used at less at possible :-).
Good work !

Umm...  15757 frames in 5,0 seconds =   3151,400 FPS
And it made my computer to emit quiet high pitched noise, which I have
never heard before.
My video card is passively cooled, so it's not fan.

Subject: [Gambas-devel] Interface of gb.opengl.sge
Message-ID: <5153ADE0.7000804@...1...>

Hi Tomek,

I took a glance at your code, and I strongly suggest the following 
changes to the gb.opengl.gse interface before you go further.

Why these changes? Mainly because I try to make Gambas components have 
the most similar interfaces as possible, so that the learning curve is 
lower.

By the way, not that there is a design problem too : the MD2 model 
loading routine only works if the endianness of the CPU is the same as 
the endianness of the file. You should ensure that if the endianness is 
different, you swap the binary data accordingly.

Now the old interface :

GB_DESC Md2ModelDesc[] =
{
   GB_DECLARE("Md2Model", sizeof(MD2MODEL)),
   GB_NOT_CREATABLE(),
   GB_STATIC_METHOD("Load", "Md2Model" , Md2Model_Load, "(Name)s"),
   GB_METHOD("SetPosition", NULL, Md2Model_SetPosition, "(X)f(Y)f(Z)f" ),
   GB_METHOD("DrawFrame", NULL, Md2Model_DrawFrame, 
"(Frame_No)i(Texture)i" ),
   GB_METHOD("DrawInterFrame", NULL, Md2Model_DrawInterFrame, 
"(Frame_No)i(InterFrame)f(Texture)i" ),
   GB_METHOD("GetFramesNo", "i", Md2Model_GetNoFrames, NULL ),
   GB_METHOD("GetFrameName", "s", Md2Model_GetFrameName, "(FrameNumber)i" ),
   GB_METHOD("Scale", NULL, Md2Model_Scale, 
"(Scale_x)f(Scale_y)f(Scale_z)f" ),
   GB_METHOD("_free", NULL, Md2Model_free, NULL ),
   GB_END_DECLARE
};

The new one I suggest:

GB_DESC Md2ModelDesc[] =
{
   GB_DECLARE("Md2Model", sizeof(MD2MODEL)),
   GB_NOT_CREATABLE(),
   GB_STATIC_METHOD("Load", "Md2Model" , Md2Model_Load, "(Name)s"),
   // 'SetPosition' renamed to 'Move'
   GB_METHOD("Move", NULL, Md2Model_SetPosition, "(X)f(Y)f(Z)f" ),
   // Three properties to get/set the one coordinate
   GB_PROPERTY("X", "f", Md2Model_X),
   GB_PROPERTY("Y", "f", Md2Model_X),
   GB_PROPERTY("Z", "f", Md2Model_X),
   // A virtual object for accessing frame properties and count
   GB_PROPERTY_SELF("Frames", ".Md2Model.Frames"),
   GB_METHOD("Scale", NULL, Md2Model_Scale, "(ScaleX)f(ScaleY)f(ScaleZ)f" ),
   // Maybe you should add ScaleX, ScaleY and ScaleZ properties too.
   GB_METHOD("_free", NULL, Md2Model_free, NULL ),
   GB_END_DECLARE
};

GB_DESC Md2ModelFramesDesc[] =
{
   GB_DECLARE_VIRTUAL(".Md2Model.Frames"),
   // Was Md2Model_GetNoFrames
   GB_PROPERTY_READ("Count", "i", Md2Model_Frames_Count)
   GB_METHOD("_get", ".Md2Model.Frame", Md2Model_Frames_get, "(Frame)i"),
   GB_END_DECLARE
}

// The _get method of Md2Model_Frames is implemented that way:

BEGIN_METHOD(Md2Model_Frames_get, GB_INTEGER frame)

   // Store the frame number into the object, it will be used immediately
   // by the method called on the virtual .Md2Model.Frame object.
   // Maybe check that the frame number is valid now.
   // And don't forget to add the 'frame' field into the object
   // structure.
   THIS->frame = VARG(frame);

END_METHOD

GB_DESC Md2ModelFrameDesc[] =
{
   GB_DECLARE_VIRTUAL(".Md2Model.Frame"),
   // Was 'Md2Model.DrawFrame'
   GB_METHOD("Draw", NULL, Md2Model_Frame_Draw, "(Texture)i"),
   // Was 'Md2Model.DrawInterFrame'
   GB_METHOD("DrawInterFrame", NULL, Md2Model_Frame_DrawInterFrame, 
"(InterFrame)f(Texture)i"),
   GB_END_DECLARE
}

Tell me what you think about that and if you have questions!

Hi Jussi,
What GPU is on your card?
Could you try to set screen.framerate in main sub to some lower number 
and see what happens?

Tomek.

Hi Benoit,

Thanks for your suggestions, I will try to do as much a I can using 
devel-api documentation page. It's the best way to learn I think. When 
I'm stuck, I'll ask for your help, ok?
Question 1 - How do I check endianess of the CPU from component level?
One more question - what would be the best way to make the class 
creatable - Md2Model_new I suppose, but what should be in that function? 
Can it be empty? Without creatable class I can't make an array of it.

Thanks,
Tomek

You must read a well known two or four bytes integer value from the file 
with fread, and see if you get it swapped or not.

If you get it swapped, then you know that all binary values must be swapped.

You can use the magic identifier at the beginning of the file, but 
beware that you must check it byte by byte before reading it as a binary 
data.

Otherwise you may take some files starting with the magic number 
inverted as MD2 model files!

Yes, you must be able to create void models, and manage them in all 
functions.

If a void model must not be used anywhere, you can use the "check hook".

You declare the check hook in the class description structure with:

GB_HOOK_CHECK(my_check_function),

Then 'my_check_function' must be a function taking a pointer to a 
Md2Model object and returning an integer different from zero if that 
object is invalid. (The interpreter will raise the 'Invalid object' error).

Moreover, you must think about implementing boolean operators between 
models if it has some sense (merging two models for example). I have no 
idea, not being an OpenGL expert, but if you want to implement such a 
thing, then a void model must be perfectly valid then.

GeForce 8600 GT
I found out that the noise is just coil whine.
It seems to be just coincidence that this example hit the resonance
frequency.

As I absolutely have no means to test Big-Endianness, I think I'll just 
put GB.Error("Big Endian not supported yet."), if reading header gives 
reversed value.

Is it similar to cquad class in GLU? But Md2Model has no external 
initiator as quadric do.

I made some changes if file, but cant figure out how to return frame 
object. File Md2Model.c attached.

I think the better strategy would be to *try* to implement endianess-neutral
code and let big endian users complain if it doesn't work correctly. The
obvious rationale is that you make progress with this method.

I don't know anything about the files you're opening but endian problems can
easily be solved by means of <endian.h>. Is there any reason not to use it?

Regards,
Tobi

No idea. :-)

But if you have two models, maybe it is possible to create one model 
that is the union of both. But I have no idea if it is possible or 
useful. I just told you so in case.

Sorry, I forgot a line:

BEGIN_METHOD(Md2Model_Frames_get, GB_INTEGER frame)

   // Store the frame number into the object, it will be used immediately
   // by the method called on the virtual .Md2Model.Frame object.
   // Maybe check that the frame number is valid now.
   // And don't forget to add the 'frame' field into the object
   // structure.
   THIS->frame = VARG(frame);
   GB_RETURN_SELF();

END_METHOD

Then the Md2Model_Frame_Draw method does not take the frame number as 
argument anymore. It will use 'THIS->frame' internally instead.

Hi Benoit,
I have problems with understanding how the _get method works. After the 
changes my model seems stuck at frame[0] and I know I have to pass the 
frame number to my model but don't know how.

Thanks,
Tomek.
