Load a terrain bigger than 515 x 515

[GameFilesOpen]

Hi community,
can you help me to load a map bigger than 515 x 515? my map is 515 x 643.

Thanks to all.

When you create your terrain, are you using addTerrainMesh, or addTerrainSceneNode?
I believe the TerrainMesh can accept high res height maps (look at iscenemanager.h in the source).
THe TerrainSceneNode needs its height map pixel resolutions to be values of 2^N+1 (129x129, or 257x257, or 513x513, etc).

If changing the terrain type is a lot of trouble, try changing the pixel resloution of your height map.

Can you show me a simple example of addTerrainMesh?

Have you tried compiling and running Example 12?
It already has a Terrain Scene Node. I modified the example to be switchable between the two terrain types:

Code: Select all

	if (iTerrainType == 1){ //Terrain Mesh

		video::IImage* colorMapImage = driver->createImageFromFile("C:/Program Files/irrlicht-1.7.1/media/terrain-texture.jpg");
		video::IImage* heightMapImage = driver->createImageFromFile("C:/Program Files/irrlicht-1.7.1/media/terrain-heightmap.bmp");

		scene::IAnimatedMesh* terrain =   smgr->addTerrainMesh ("TerrainMeshName", colorMapImage, heightMapImage,
			core::dimension2d< f32 >(fTerrainScale, fTerrainScale), // size of a pixel
			8.f*fTerrainScale); // maximum height

		scene::ISceneNode* room = 0;
		ISceneNode* node = smgr->addAnimatedMeshSceneNode(terrain);
		node->setMaterialFlag(video::EMF_LIGHTING, false);
		node->setPosition(core::vector3df(-5000,0,-5000));

}	else if (iTerrainType == 2){ // height map needs to be 2n+1 resolution
// add terrain scene node
		scene::ITerrainSceneNode* terrain = smgr->addTerrainSceneNode(
			"C:/Program Files/irrlicht-1.7.1/media/terrain-heightmap.bmp"
			,0,-1
			,core::vector3df(0.0f,0.0f,0.0f) // position
			,core::vector3df(0.0f,0.0f,0.0f) // rotation
			,core::vector3df(1.0f,1.0f,1.0f) // scale
			,video::SColor(255,255,255,255)
			,3 // Level of detail
			,ETPS_17 // terrain patch size
			,0 //smooth factor
			);

	terrain->setScale(core::vector3df(fTerrainScale, 1.0f, fTerrainScale));
	terrain->setPosition(core::vector3df(-5000,0,-5000));
	terrain->setMaterialFlag(video::EMF_LIGHTING, false);
	terrain->setMaterialTexture(0, driver->getTexture("C:/Program Files/irrlicht-1.7.1/media/terrain-texture.jpg"));
	terrain->setMaterialTexture(1, driver->getTexture("C:/Program Files/irrlicht-1.7.1/media/detailmap3.jpg"));
	terrain->setMaterialType(video::EMT_DETAIL_MAP);
	terrain->scaleTexture(1.0f, 20.0f);
}

The code above shows the differences in the ways the two terrain types are used.
If you search the forum for addTerrainMesh, you'll probably find some other more complete examples.

Thanks very much, you're a monster!

P.s. sorry for the long time passed before the thanks ^^
