    TEXTURE_BASE_LEVEL and TEXTURE_MAX_LEVEL

    Is it "legal" to have the base level and the max level to be equal, essentially eliminating the effect of mip mapping without having to change the filter.

    EDIT : just re-read your question. I misunderstood what you were asking.

    Yes you can set base and max levels to the same value. That's basically "turning mipmapping off".

    Re: TEXTURE_BASE_LEVEL and TEXTURE_MAX_LEVEL

    It's definately possible.
    Taken from the specification at http://oss.sgi.com/projects/ogl-samp...exture_lod.txt :
    Mipmap Completeness
    -------------------

    The GL Specification describes a "complete" set of mipmap image arrays
    as array levels 0 through p, where p is a well defined function of the
    dimensions of the level 0 image. This extension modifies the notion
    of completeness: instead of requiring that all arrays 0 through p
    meet the requirements, only arrays 0 and arrays BASE_LEVEL through
    MAX_LEVEL (or p, whichever is smaller) must meet these requirements.
