    I am currently developing for iPhone, using the PowerVR SDK to have a windows version.

    Apple docs says that the iPhone supports LOD bias.
    And I know that a GL_EXT_texture_lod_bias extension exists for OpenGL ES 1.1.
    The problem is that I have absolutely no clue on how to set the load bias using PowerVR SDK…

    With “classic” openGL i would do :

    But in the Power VR sdk headers, GL_TEXTURE_FILTER_CONTROL_EXT and GL_TEXTURE_LOD_BIAS_EXT do not exist !

    Thank you for your help
