Irrlicht Engine

thankyou, good advice

let us have a flat terrain, this terrain is a scene node containing a mesh.

I'd like to subdivide all (or a part) of this terrain in a grid of cells, so when I roll the mouse over the terrain I can highlight the cell the mouse is in.

How can I do that? How to get the coordinates of the collision ...

it's a LOD setting problem. search the API for the function and how to set LOD properly (Level Of Detail).

sorry, I find the solution. Just put
in the code

Hi guys. I'm trying to apply a transparent texture on the default cube of Blender. The texture is a .png 256x256 image.

The texture is UV mapped. In the blender 3D window the texture looks correctly transparent, but as I export the .obj model and load it into irrlicht, the transparent zones are ...

You could subdivide your terrain in big sectors - each of them is a mesh. You could model your terrain with a modeling software, like blender, and apply how many textures you want in the places you want. Then save the model in any suitable 3d format (like .OBJ) and load into irrlicht

Hi guys. just a nooby question :)

Let's say I make a c++ program in wich I define my own Game class. Obviously, Game class has members like
- IrrlichtDevice* device;
- IVideoDriver* driver;
..and so on.

The device is created in the Game class constructor. A run() method contains the game loop ...

mmh I will give it a try, thanks

Hello guys. My question is simple.
I just wanna load an xml config file through IXMLReader and read few useful parameters like:
- video driver
- screen resolution
- ...others...

I know I need this line of code

IXMLReader* xml = device->getFileSystem()->createXMLReader("...");


but I can put it ...

..or dividing map into regions and simply checking in which region the player is at every frame, and then updating the LODs of meshes in each region

Hello everybody. I was wondering on how to make and render a really big map.
I'm not going to use the TerrainSceneNode but a simple mesh for the terrain. The problem is all the amount of objects (trees, houses, stuffs, etc) contained in the map.
I was thinking about making two (or three) versions of ...

200 is not power of 2. powers of 2 are:

2, 4, 8, 16, 32, 64, 128, 256, 512, 1024 ...

the texture is 512x512.
Tiles are 64x64.
So, all of them are 2^n.

The console log is:

Irrlicht Engine version 1.4.1
Microsoft Windows XP Professional Service Pack 2 (Build 2600)
Using renderer: OpenGL 1.5.0
Intel 965/963 Graphics Media Accelerator: Intel
OpenGL driver version is 1.2 or better ...

I started messing around with the 2D parts of Irrlicht and am trying to load a large background image. Unfortunately, it won't load and I don't know why. Heres the code that creates and displays it and the error message. The image is located in the same folder as the project code.

It should be ...

@arras
you were right, on another machine drawing nothing
D3D -> 1700 FPS
OGL -> 1100 FPS
SW -> 350 FPS

Drawing 100 tiles
D3D -> 1200 FPS
OGL -> 900 FPS
SW -> 290 FPS

Drawing 10,000 (100x100)tiles all on screen
D3D -> 49
OGL -> 49
SW -> 17

Drawing 10,000 tiles but only 24x24 on-screen
D3D -> 570 ...
