    My program crashes at glTexImage3DEXT

    Hi All,
    i have a C++ application that uses GLUT .. this application reads volume data from a file and display it
    i'd like to get rid of the GLUT and work under MFC
    The old program proceeds as following:
    ---------------------------------------
    ->create window using GLUT
    ->check if GL_EXT_texture3D Extention is supported
    ->init texture
    ->Draw
    .
    .
    ------------------------------------------------
    now [after working under MFC] the program crashes
    at calling glTexImage3DEXT

    any idea about what may cause that error?

    Make sure function pointer of glTexImage3DEXT is not null.
    Make sure the data array you pass has the good size, changes in default alignement may make it work in one case and not the other.
