Irrlicht Engine

The problem is that the scene layout is generated dynamically so I'd have to generate the mesh dynamically too. Sadly, I have no idea how to do this, are there any tutorials on that topic?

In a game I'm working on a lot of objects are loaded (around 15000). They all just have 2 polygons, but the game is really slow on my machine (0.5 FPS). I'm assuming this is because I'm using the default scenenodes. Can I make the game faster somehow? Would writing a custom scenenode help?
And ...

I'm trying to use shadows in my project, but I'm getting strange results. The light source is following the player (just a cube so far).

A example without shadows:

Same thing with shadows (There is a gap in the shadow and a strange shadow ...

I'm using the netbeans IDE, and have the problem that I don't know where I have to save images if I want to load them as textures.
Saving with the source files won't work, saving to the executable isn't working, neither just adding to the project.
Where do I have to save it?

Can I get another hint?
After setting up OpenGL I get other errors:
/home/eric/Programmieren/c/irrlicht-1.5/source/Irrlicht/CIrrDeviceLinux.cpp:1088: undefined reference to `XF86VidModeQueryExtension'
I already tried the things described here

Sorry for all the questions, but I seem to have ...

OK, the compiling worked after I knew whcih packages I had to install, but now my compiler is throwing a crazy amount of errors like What am I doing wrong?

Is there any precompiled irrLicht library for linux? There is none in the version you can download, and I'm too stupid to compile it myself

How can I add an ambient light with IrrLicht?

I tried it with a FPS camera before, but now I tried to disable light and it works.

After a bit 2D I wanted to try something in 3D. But my Code doesn't work:

#include <irrlicht.h>

using namespace irr;

#ifdef _IRR_WINDOWS_
#pragma comment(lib, "Irrlicht.lib")
#endif


int main() {

IrrlichtDevice *device = createDevice(video::EDT_OPENGL, core::dimension2d<s32>(800, 600 ...

I'm trying to make a little test programm with IrrLicht, but I cant' get it to draw images. My (relevant) code:


IrrlichtDevice *device = createDevice( video::EDT_OPENGL, core::dimension2d<s32>(800, 600), 16,
false, false, false, 0);
if (!device)
return 1;
device->setWindowCaption(L"Hello ...
