btw. you speaking german ?
No.

Heh, one more question: How can I set node transparency (like EntityAlpha in B3D) ?

Can use vertex transparency without lighting being on? Is this a bug or?

Just a might be stupid question:
Why do we need a Irrlicht wrapper?
As I could see, Irrlicht comes with a dll. Why not simply load the dll als lib and that is all?

It's an object oriented engine, so it needs a wrapper to work it's best with PureBasic. That being said, the integration could be better ;)

Hm, I do not really understand, what that means.

I want to use the irrlicht engine for rendering terrains, landscapes, produced with my terrain generator GeoControl.
So, the user interactions would be solved with PB. that then gives the commands to the irrlicht engine.

Is this not possible, or is it more, that I have to think more objectorientated?

I need the functions for loading a 16bit raw terrain, resolution up to 8192, but 4096 would be enough, for textures for those terrains, shadows and lightning and may be GI. Also a inifinte water plane and water shaders.

Can your wrapper do this?

It is really urgent. I want to release the second version in the first half, and if the 3D engine works good, I will have to recode some things, to work in 3D.

While it's absolutely possible to directly use the DLL using interfaces
(COM) up to a certain extent, there're still too many things that had to be
changed inside the DLL in order to make it properly work from PureBasic.

For example, a lot of functions return byVal which leads to crashes as
PB can't handle this. Other (necessary) functions aren't exported at all,
meaning you'd have to re-code them in PB or change the DLL accordingly.

Whatever you look at it, the original DLL or LIB can't be used so there
are only two options left: Write a C-ish wrapper and surrender OOP or
change the DLL.
Good programmers don't comment their code. It was hard to write, should be hard to read.

Thanks for that explanation, now I see the problems.
That seems to be a bit a weak point of PB. The Ogre engine does not have a wrapper to PB, and the implementation in PB itself is .............

So, it looks like buying ColdSteel, if it is far enough or using the wrapper here.

No, the Ogre PB Engine is going that way:

and fact is that the 'coldsteel' is not more than a wrapper for irrlicht,
as its based on that sources.

Well, just tested the wrapper.
Seems, like only the silly 8 bit terrains can be loaded.
I have read that there is a patch for support of 16 bit terrains in Irrlicht.
