Irrlicht Engine

I've got a similar problem, hope these two functions may help you. By the way, I still didn't test to see if there's a memory leak in the first one.

const wchar_t *str2wchar_t(string str)
{
// null-call to get the size
size_t needed = ::mbstowcs(NULL,&str[0],str.length());
// allocate

Hi,

in my project of drawing different countries, I got stuck with this requisite of terrain maps having to follow the rule 2^N + 1.

For Brazil, height map get about 588x585 pixels. So I stretch it to 1025x1025 (2^10 + 1), no problem.

The problem arrives with Indonesia. Its height map get about ...

Hi,

I wonder why there are only those two options in the search query:

Search topic title and message text
Search message text only

since many searches return hundreds (or thousands) of results, and an option "Search topic title only" could reduce dramatically to the more useful results?

For the case anyone run into a similar problem:

Project options:
Search directories:
Compiler:
......irrlicht-1.5\include
Linker:
......irrlicht-1.5\lib\Win32-gcc (or anyone you're using)

and
Linker settings:
Link libraries:
......irrlicht-1.5\lib\Win32-gcc\libIrrlicht.a

That's all!

Hello Arya and Katsankat, thanks for the replies!

Right now I'm studying Arras' tiled engine (ShTlTerrainSceneNode - http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=20940), since some maps, like Brazil, are pretty huge to show in many computers (specially laptops) as a whole thing.

Arya, up ...

Hey! I'm getting a similar problem. I've downloaded the ShTlTerrainSceneNode and was trying to compile it. I only had to change a single line

scene::E_DEBUG_SCENE_TYPE dtype = terrain->isDebugDataVisible();

to

scene::E_DEBUG_SCENE_TYPE dtype = scene::E_DEBUG_SCENE_TYPE(terrain->isDebugDataVisible ...

Well, here are some images of the previous (2d) version (available at http://ufpr.dl.sourceforge.net/sourceforge/simnation/SN_0.3_Full.zip ), so you can understand the project better:

Main screen, showing a selected country with the cities (passing the mouse over a city shows its name and ...

Hi,

I want to load the texture completely in the terrain, without cutting or repeating it. Since each texture is a country, what I do is:

1) cut a world altitude map for the country region (this creates a small bmp, which is loaded with smgr->addTerrainSceneNode);

1.1) this map has to be scaled ...

Hey, hybrid, thanks a lot! It worked fine, or almost: the lines are not "attached" to the terrain. Look the screenshot:

The red lines are the roads. Some of them float much above the terrain, others much below it.

My code is:

P = Points[k ...

Hi fellows,

My project is a simulation of real countries, with data about population growth, land use, biodiversity, energy budget, foreign trade, industries, agriculture, ocupation of the working class, and so on.

The main idea is to teach people how things happen in real world, so they won't ...

Well, now I think I understand what the indices do (they do 2 triangles to form a rectangle, that will be my line, right?).

I tried with

typedef video::S3DVertex TQuad[4];

but this array didn't work. Now I'm putting all the vertex together in one vector (Quad).

// by the way, in my version of ...

Thanks for the information, hybrid. I'm basing myself in the example 3 (from the tutorial), I already got the tetraeder to appear together with my map.

"With the latter you can put all shape points into one array, build the index list for it, and draw all lines in one go."

How do I build the index ...

Thanks hybrid. But what do you mean "same sized lines": same thickness or same length (or anything else)? Here in Brazil it only works with OpenGL, so that wouldn't be a limitation right now (but I want my code to be as portable as possible, so...)

I think the other option is the one (draw thin ...

Hi,

I'm drawing country maps with irrlicht, and it's working really nice! I've got many shapefiles with data that I want to draw on those maps, like roads, but I don't know how to do it. I read the lines from the shapefile (.shp), this obviously can't be done inside the main loop.

I wanna have ...
