Irrlicht Engine

Ok, I think i'll do the same thing.

Thank you for answering.

Hello,

I'm trying to load a md2 mesh in my own renderer (nothing to do with Irrlicht). It works quite well, but i've got some problems with a few models (faces are disappearing).
After investigating, it seems that it's a blender exporting problem with the generation of "gl_commands" in md2 files ...

Thanks for the answers.

I haven't thought i'd have to manipulate transformation matrix.
That's an interesting discovery :D
Matrix in Irrlicht seem to work the same way as OpenGL do (modelview, projection ..).

Doing the change in my code with adding

driver->setTransform(video::ETS_WORLD, core ...

Hello,

Let's call "Irrlicht's normals representation in debug mode" BYA (i.e. big yellow arrow)

1) Why BYA aren't connected to the vertices of the pyramid ? They wander in the space, they should be connected to the matching vertex (even if the normal's computing is wrong.)

2) What do you call ...

- Hey, it seems nobody replied to me.
- Yeah . Perhaps the question was not so obvious ?
- You're right dear me. Let's sum this up.
- Oh me, you're so smart.


Well, the question was:
is my normal computing done right ?

And, another one:
why the display of the normal with irrlicht's debug mode is ...

Well, hello everyone.

I tried to compute normals on a small object (a pyramid).
The results are strange, when i turn on "normals display" in debug mode.

I got this:

Hmmm strange normals.. i wrote some code to display normals my own way. Here ...

Hello,

I'd like to know if there's a way to display on screen light statistics.
You know, like the bounding boxes or normals on the meshes.

I tried :


light=scenemgr->addLightSceneNode(0,irr::core::vector3df(0,20,0));
light->setDebugDataVisible(irr::scene::EDS_FULL);


but it displays ...

Oh... so much answers in such little time lapse.
So it was my camera after all. (and the precision problem in my function).

Thank you :D

Of course, as you noticed, i did parameters mistake (int and not float in "create_hexagon" function.)
I would have bet that "-Wall" parameter in compilation ...

Hello,

I'd like to generate a simple mesh.
It's a hexagon.
This code compile without error with


g++ 04-hexagons.cpp -o 04-hexagons.elf -I/usr/include/irrlicht -L/usr/X11R6/lib -lX11 -lXxf86vm -lIrrlicht -lpng -ljpeg -lGL -Wall


Obviously, i've screwed up something, because it shows nothing at ...

Hello,

I tried to give a gun to Sydney (md2 model from media directory of Irrlicht's samples). Alas, I rapidly understood that md2 formats (and all morphing animation based formats) were not designed for this kind of stuff.

Ok, so what's else ? Skeletal animation with bones, nice!

Not so fast ...

Ok, i've modified a bit the first sample of Irrlicht sample dir.
I've added bounding box visibility.
You can see that the bounding box doesn't change while Sydney is running.

Here is the complete code for testing:


/* based on irrlicht sample: 01.HelloWorld
i've stripped all i could, to only ...

Some animated mesh do that, e.g. md2. So I don't understand why yours doesn't :?

Hmm well, i don't understand either

The nice running woman on the screenshot is "sydney.md2" and comes from the "media" directory of Irrlicht.

So the bounding box should grow when Sydney is running, should'nt it ...

Hello.

As a little drawing say more than lot of words, let's look at this:



How ugly.

It would be nice if IAnimatedMesh could update the bounding box while the animation is running.

Is it possible ? Or may i have to do it myself ?

"Hello me, it's me again!" (Megadeth!)

Well i've found out what to do with bounding box.

With bouding box, you cannot modify directly mesh buffers. You have to edit the Imesh, after having included the mesh buffer of course.

That gives :


(blah blah and then ...)

for (int i=0; i<12; ++i ...

I usually use gcc, but if i remember well, you just have to include library on the cl command line.

Libraries which are not found don't return an error at the compilation stage. It's when linking than you get an error, if the library is not found by the linker.

Check these 2 things:
- Is "Irrlicht ...
