Where is GL_TEXTURE_MIN_LOD on the iPhone?

Question

Is there an equivalent ? Is it an iPhone limitation or an OpenGL version limitation ? I can't find the mipmap level feature anywhere.

ES 1.1 doesn't support it.

Though you might check if your implementation has EXT_texture_lod_bias.

I tried that but my texture renders blank. I can't find what's wrong – CodeFlakes Feb 25 '11 at 18:21
@CodeFlakes: That IS how you set up mipmapping. If it renders blank then most likely you don't have any mipmaps in your texture? Do you generate them? Use glGenerateMipmapOES. – Goz Feb 25 '11 at 18:24
Actually what I want is not use mipmap but if I don't unless I select GL_NEAREST or GL_LINEAR my texture is white. Sorry if this is a silly remark. I'll check glGenerateMipmapOES. Thanks – CodeFlakes Feb 25 '11 at 18:27
