[FIXED]How do i apply bump map?

[MasterM]

pleas help me with this guys...

One of the beginning tutorial (one with the small dwarf in the small room) has textures added to the walls, you can choose if you want bump or parlax mapping, so check it out.

I think you mean tutorial 8...i checked it but found nothing on bump mapping :S...if anyone know my problem pleas tell me...i am really lost :/

No, example 11. It's using the same room, but a sphere instead of the dwarf...

for some reason when i use the following code i get the followong results :

int main(int argc, char** argv)
{
IrrlichtDevice *device =
createDevice(EDT_OPENGL, dimension2d<s32>(640, 480), 32,
false, false, false, 0);

IVideoDriver* driver = device->getVideoDriver();
ISceneManager* smgr = device->getSceneManager();
IGUIEnvironment* guienv = device->getGUIEnvironment();

driver->setTextureCreationFlag(video::ETCF_ALWAYS_32_BIT, true);



scene::IAnimatedMesh* sarMesh = smgr->getMesh("sars.3ds");
scene::ISceneNode* room = 0;
IMeshSceneNode* sars;
if (sarMesh)
{
smgr->getMeshManipulator()->makePlanarTextureMapping(
sarMesh->getMesh(0), 0.003f);

ITexture* colorMap = driver->getTexture("textures/sars.jpg");
ITexture* normalMap = driver->getTexture("textures/sarsbump.jpg");

driver->makeNormalMapTexture(normalMap, 9.0f);

scene::IMesh* tangentMesh = smgr->getMeshManipulator()->createMeshWithTangents(
sarMesh->getMesh(0));


sars = smgr->addMeshSceneNode(tangentMesh);
sars->setMaterialTexture(0, colorMap);
sars->setMaterialTexture(1, normalMap);

sars->getMaterial(0).SpecularColor.set(0,0,0,0);
sars->setMaterialType(video::EMT_PARALLAX_MAP_SOLID);
sars->getMaterial(0).MaterialTypeParam = 0.035f;

sars->setMaterialFlag(EMF_LIGHTING,true);
tangentMesh->drop();
}


ISceneNode* lit=smgr->addLightSceneNode(0,vector3df(90,90,90), video::SColorf(255.0f,255.0f,225.0f));
smgr->addCameraSceneNodeFPS();

while(device->run())
{
sars->setRotation(vector3df(0.05,0.05,0)+sars->getRotation());

driver->beginScene(true, true, SColor(0,200,200,200));

smgr->drawAll();
guienv->drawAll();

driver->endScene();
}

device->drop();

return 0;
}

and i get the following results :

but the model itself isnt that color...

I really dont know whats the problem but i tihnk it has to do with the tangets...if someone know the problem pleas help me .

[dlangdev]

can you take out the line...

Code: Select all

smgr->getMeshManipulator()->makePlanarTextureMapping( 
sarMesh->getMesh(0), 0.003f); 

also if sarsbump is already a bump map (and not a heightmap) then take out the line...

Code: Select all

driver->makeNormalMapTexture(normalMap, 9.0f); 

[MasterM]

Thank you and what does the line does that effects the color?
