Irrlicht Engine

One thing I notice OpenGL driver is that I needed to change how MaxSupportedTextures is set up in the COpenGLExtensionHandler() ctor. Currently its:
if (Version>102 || FeatureAvailable[IRR_ARB_multitexture])
{
glGetIntegerv(GL_MAX_TEXTURE_UNITS, &num);
MaxSupportedTextures=static_cast<u8>(num ...

wait... does it mean that I basically have to go through the environment map, pixel by pixel.... treating them all like diffuse parameters and unprojecting the envmap texcoords as normals/lightdir then adding them to THE 9 xyz/rgb values of a 2nd order spherical harmonic?

Then render a virtual ...

It's a pretty complicated subject, you have to be unafraid of dealing with alot of mathematics notation to get to grips with it (and really reading it not just skipping past the maths and reading the code).

A couple of things I found helpful:

I've had issues with all the available skinned, animated mesh formats in Irrlicht that can be exported from 3DS Max...


.X is what I'm mainly using, but both the available exporters (KW-export and Panda) have bugs. KW is the best but some animated meshes get screwed up, it appears that some verts ...

Another big reason for supporting skinning in Collada is both the .X exporters (KW export and Panda) have bugs.

Is a B3D exporter available for Max 2010 or 2011 ?

What is the best Ogre exporter to use ? There is a OgreMax but it costs money.

So that beast model works fine (with my patch from this thread: http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=42050). Here is a screen shot from the PerPixelLighting example:

Here is the code to load it:

My reading of the code is that its an either-or thing. You can't have 2 UVs and tangents, only one or the other. That is a bit of a pain (it means you can't have lightmaps and normal-maps)

Cool. Will def try that. Though that X file has no tangents. So I'll need to add a function to add tangents to a skinned mesh.

Splendid! Going to test it asap.

The collada format also contains binormal and tangent information (and there are excellent Collada exporters for most major design apps). Could you possibly also do the same for Collada (.dae) loader? That would be a great and *very* needed addition.

Thanks for ...

The following line looks suspicious:


if ((tangentpos != -1 && tangentpos == 1) || (binormalpos != -1 && binormaltype == 1))


Did you want to check for tangenttype instead of 2 times for tangentpos?

Indeed, well caught, should have read:

if ((tangentpos != -1 && tangenttype == 2 ...

Don't know about the fast_atof change, I don't think that is correct (as the value can't be larger than UINT_MAX), what was your reason for changing this?

Ah yeah, the X loader was hitting that error case in findNextNoneWhiteSpaceNumber. If the number to be read was larger than INT_MAX (but less ...

I am trying to find a decent animated, normal mapped character in 3DS max for an Irrlicht based tech demo I'm putting together. Subject isn't that important (typical game subject matter is fine, soldier, alien, zombie, whatever). Doesn't need huge range of animations (just a walk would be ok).

I ...

Looks very cool. Apologies if I'm being dense, but how do you go about building it on Visual Studio ?

I see some CMake files further down in the source tree (in some of the sub folders of irrBullet-0.1.65\source\bheaders\Bullet\BulletCollision) but nothing in the root Source folder.
