Irrlicht Engine

I dont know if anyone noticed it but when irrlicht does joint rotation interpolation the animation "flickers".

What i mean by "flickers":
When i slow down my animation x1000 (it barely moves) i can see that "flickers" are not really "flickers" but a very fast rotations by 360 degrees especially at ...

Can anyone reply me on the Second question about Shader ?
I already know about Y up axis. There is no need to explain it anymore.

Ok problem solved.

You have to create separate vertices for each triangle you want to color.
If you share vertices then its obvious that you share its colors too.

Some time ago i had the same problem and i created additional method named "addMeshTangents" in MeshManipulator class. I dunno if its correct but works for me.

Some admin could add it to SVN. Its better than createMeshTangents and works with AnimatedMesh as well as Static.

void CMeshManipulator ...

I dont want to create another thread so i post it here. Its also kind of related to the XYZ axis problem so here it go:

I used the shader i posted before just as it is with simple plane "terrain" and i cant get it work with irrlicht. What am i doing wrong ? Or maybe i have to do it in some special ...

32bit applications can run normally on your 64bit OS.

The only thing you can't do is to use 32bit irrlicht.dll with your 64bit compiled program/game.

You would have to recompile irrlicht.dll to 64bits in that case. I already tested it and it seems to work fine in x64 mode.

Then why shaders are made other way?

Like this one:
http://irrlicht.sourceforge.net/phpBB2/ ... p?p=221252

I tried to run that and i cant make it work correct.
Any (example) help ?

I have found something like "upVector" is it ok if i change it to vector3df(0,0,1) ?

It should make:
X - horizontal
Y - depth
Z - vertical

But in that way i would need to rotate each node by 90 degree :F
Isnt there any easier/faster way ?

Its a really nice shader and i would like to use it but as i see irrlicht uses Y axis as height and that shader uses Z axis as height so it doesnt work with irrlicht.

Can anyone post a C++ source code to run that shader in Irrlicht ?

Ok NVM i already got it.

I think its the Camera problem. You could change the projection matrix to RightHand here:

void CCameraSceneNode::recalculateProjectionMatrix()
{
ViewArea.getTransform ( video::ETS_PROJECTION ).buildProjectionMatrixPerspectiveFovLH(Fovy, Aspect, ZNear, ZFar);
}

and use ...

Ok ok but how did you managed the XZY swap to XYZ ?
You made that globally ?

Btw. Im trying to run that shader:
http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=24794

Do anyone has c++ source code for this sample ?
As i can see it uses XY axis instead of irrlicht's XZ and i cant make it look ...

Hum. What wrapper ?
Can you tell me more about that ?

Yes i know what "Normal" is. Im just telling that DirectX and OpenGL uses Z axis as height and its kind of weird that irrlicht swaps it to Y.

I have tested other engines like Ogre, TrueVision and it used Z axis as height and its more correct to position anything in 2D space as XY and set its height ...

Hello.

I would like to ask why irrlicht uses some weird swapped Y <> Z (XZY) axis which gives height as Y axis instead of Z axis as it should.

It messes up most the shaders (even the irrlicht's internal ones like normal map, pseudo parallax, it uses wrong axis (Y not Z) for dot() lighting).
