Texture get blur when far away [also disappear] !!!!

[pandaben7890]

I don't know what happened to my program?

Texture get blur or disappear - -

- I use EDT_DIRECT3d9 with 32 bits and 1024*768
- videoDriver->beginScene(true,true,video::SColor(255,150,150,255));
- My Texture is 2048 * 2048 (so it has nothing to do with power of 2 texture)
- My black line is cube node from irrlicht with 64*64 black texture
- I use node->setMaterialTexture
- I tried using EMF_ANTI_ALIASING but nothing happened
- I already use EMF_NORMALIZE
- I use directional Light, so it's as you see everything is all bright

--- I have the same problem with my last program also but this time i can't stand this anymore TT

--------- Help me Plz TT -----------

What i have to do if i want them to be more clear.
and I want my black line to be more straight - -

Ps. Sorry for my bad English TT

are the black lines on that same texture? it just looks like some bad rolls with the mipmapping to me

[pandaben7890]

black lines use the same texture.
But if I use 64*64 and it's all black why you said it's about mipmapping ?

[pandaben7890]

I use EMF_ANISOTROPIC_FILTER now so the ground is now acceptable with less blur now.

But black lines still not straight and they don't have the same thickness.

If the black lines are polygons then you need to enable antialiasing (device creation parameters) to smooth the edges.
The reason why parts of them vanish at a distance is because you're drawing them too close to the ground, your z-buffer does not have enough resolution.
Either raise them up a bit so they are away from the ground, adjust your near and far plane to increase z-buffer resolution, or set up a custom render loop where they are always rendered directly after the ground but with SMaterial.ZBuffer = ECFN_ALWAYS
