i don't know how this effect is called in english so my tries to search of a solution were without success.

i have this ugly effect if i try to set water within my terrain
from a closer view it look's like that.

and far away so

what can i do ? it should be a straight coastal line without these ugly edge

don't know how to avoid this. perhaps you could cut off the landscape under the wather.
And then you draw the water first and than the landscape.

Hi, sorry dass ich auf deutsch antworte, aber ich hab keine Ahnung wie ich das mit meinem besch*** englisch ausdrücken soll.
Ich kenne dein problem. Habe ich selber gehabt als ich meine TerrainEngine für OpenGL programmierte. Letztendlich hat nur die erhöhing der Z Buffer tiefe und die erhöhung der Pixeltiefe auf jeweils 32bit abhilfe geschaft.
du kannst es ja mal versuchen, ich bin mir aber nicht sicher es funktioniert, dass es aber im fullscreenmode nicht und im windowed schon funtioniert deutet schon darauf hin.

Not following the deutsche 100% but I beleive in English the term would be an Artefact.

And I think it might be to do with the fact that the fullscreen z-buffer and windowed z-buffer are usually set separately.

I'd just double check the setup of the fullscreen mode and it's screen attributes (zbufer, coulour depth, stencil etc)

BTW make sure you have enough resolution in the z-buffer. ie don't include the zbuffer in calcs less than 1. It takes too much of the resolution for stuff near the camera.

BTW you could use the stencil buffer to explictly turn pixels off or on from drawn polys.

Hope that helps

thx @Marcus & dingo

i was searching for a funktion or a flag in the docu but i don't find them.
i only find a boolean flag how enabled or disabled the zbuffer in

driver->beginScene(...., true, ....) // the second parameter

i think you use this funktion so can you tell mell how?

NO i don't! i only used the engine included terrain secene node

Is the terrain scene node an standard node of the Irrlicht Engine 0.6? Never seen this in the documentation

Yes, it is. It's a bit buggy, though.

wow never seen so many quotes at all

Code: Select all

video::IImage* iHeightMap = driver->createImageFromFile("terrain.JPG");
video::IImage* iTerrain = driver->createImageFromFile("terrain_texture.jpg");

scene::IAnimatedMesh* iTerrainMesh = smgr->addTerrainMesh("iTerrainMesh", iTerrain, iHeightMap,core::dimension2d< f32 >(100.0f, 100.0f),5000.0f); 
scene::ISceneNode* iTerrainNode = smgr->addOctTreeSceneNode(iTerrainMesh);

Year, actually playing a bit with the ITerrainSceneNode.

What sould the detail map do? There's no difference between using it and setting NULL.
