CLOD Terrain Renderer

[Gorgon Zola]

Hi all

here's my first irrlicht project.
It's a CLOD terrain renderer for irrlicht.
([url]http://www.webtracker.ch/jahia/dl/QuadTreeTerrain.zip[/url])
it uses a quadtree algorithm and provides for in game terrain detail loading... well, sort of

it'll need a lots of improvement but it's a start.

thats cool, very nice. ill for sure use it.

[Masdus]

very nice, is it possible to use different terrain files with the demo??

Wow, i'm impressed! Looks very nice and is actually very fast.

Yep, if you have a terrain with size 256x256 in 8bit noninterleaved raw format, you could just overwrite the files in the media folder (terr*.raw are the height informations and terr*.jpg is the texture).
if you have other formats you'll have to change the code for initializing and loading of the quadtree

a very good example, i have to learn...
is it right, i understood in the code, its possible to change the terrain while using ?

Yae, you can add height data while using the terrain .
just add height data like this

Code: Select all

quadtree->addHeightData(Data,1000,2000,64,64,64,0,1,4);

this will add the height values in a64x64 array to the terrain at position
(1000,2000) the data will occupie an area of 64x2^4 meters.

but erasing is not implemented, you could overwrite the data with some neutral values though

another drawback is that you can't define yet a texture for the new inserted terrain regions... would be nice to have that too

hi all

i have put a new version of my terrain node at http://www.webtracker.ch.
changes are:
- resolved memory leaking
- added a simple version of collision detection (init phase is very slow because there is no optimisation for the trinagle selector from my side )

the compiled exe is optimized for P4 cpu, ... you'll probably have to recompile. or not, what kind of hardware is the irrlicht communitiy using anyway?

cheers

correction: just realized that the link doesn't work. You'll have to download it from www.webtracker.ch

hi there
does anyone still have the source of my terraindemo
lately my machine crashed and i lost the project

[Krampe]

I wanted to download your project this morning :/ But if your machine crashed - whats about your webspace? There should be a copy i hope?

Just so happens that I do.

Uff, Saigumi saves the day

Btw, i cant run it: "Could not load texture." I copied the textures out of the media dir into the root directory, but that didnt help either.

you'll have to recompile then it should work

one error in vc7:

root->setRenderingGlobals(driver,clippirr,Material.Texture1->getDimension(),false);

\QuadTreeTerrain\src\terrainnode\CTerrainSceneNode.cpp(77): error C2039: 'getDimension': is not element of 'irr::video::ITexture'

i creat a new vc6 projekt and added the files, now have this one error:
