View Full Version : 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".

It's definately possible.
Taken from the specification at http://oss.sgi.com/projects/ogl-sample/registry/SGIS/texture_lod.txt :
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.
