Hi There is no way unless you would re-calculate and set texcoord array each frame. You should compute texcoords for environment mapping in shader, or you can use fixed-pipeline for vertex processing(mean that you dont use vertex shader, only fragment), and in fragment shader use fixed pipeline generated texcoords to sample environment map. Drawback is that you can't use per-fragment lighting with this approach as fixed function processing calculates per-vertex lighting and dont supply normals to fragment shader.
