    How to track a matrix to the NV_fragment_program?

    Hello,

    I would like to know, whether there is a possibility to tracck a matrix to the Nvidia Fragment Program, similar to the glTrackMatrixNV for the Nvidia vertex Program?
    Thanks.

    They answer it in the spec for NV_fragment_program

    Should this extension provide tracking of matrices or any other state,
    similar to that provided in NV_vertex_program?

    RESOLVED: No.

    an open source GLU replacement library. Much more modern than GLU.
    float matrix[16], inverse_matrix[16];
    glhLoadIdentityf2(matrix);
    glhTranslatef2(matrix, 0.0, 0.0, 5.0);
    glhRotateAboutXf2(matrix, angleInRadians);
    glhScalef2(matrix, 1.0, 1.0, -1.0);
    glhQuickInvertMatrixf2(matrix, inverse_matrix);
    glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
    glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
