I have about had it with your attitude on this mailing list. Where in the following complete quote of your message do you quote the part of the spec saying the initial value of MIN_FILTER is NEAREST_MIPMAP_LINEAR? The quotes from pp 77, 69, 87-88 all have to do with NPOT textures. Yes the quote from p81 is more general but will have done nothing to inform the OP of his fundamental issue.On Sun, Apr 21, 2013 at 8:20 PM, Mark Callow <firstname.lastname@example.org> wrote:
Florian focused on NPOT issues and missed the more fundamental issue.Did not. Re-read specification quotes, all relevant sections related to filtering, pyramid completeness and POT are quoted.

3.7.1, Page 69, on texImage2DIf level is greater than zero, and either width or height is not a power of two, the error INVALID_VALUE is generated.

3.8.2, Page 88A two-dimensional sampler is called, the corresponding texture image is a
non-power-of-two image (as described in the Mipmapping discussion of
section 3.7.7), and either the texture wrap mode is not CLAMP_TO_EDGE, or
the miniﬁcation ﬁlter is neither NEAREST nor LINEAR.
