    how to use glFogCoordEXT in GLSL

    I used glFogCoordEXT to distinguish explored and unexplored terrain. But after i use a shader for normal mapping on terrain, its working fine but the fog is no more there.

    can some one please help me, (i don't know glsl).

    When you have a fragment shader active, it replaces the fixed function shading pipeline. This includes fog.

    Instead, send the fog attribute as a vertex shader input and apply the fog effect in your shader.
