I'm currently experimenting with a change like this and so far I don't
experience any drawbacks:

- const float noiseDist = fmodf(- totalTime * my_shader->_factor *
my_shader->_speed, 4.0f);

my_shader->_speed, 4.0f);
glMatrixMode(GL_TEXTURE);
glLoadIdentity();
glTranslatef( noiseDist, 0.0f, 0.0f );
Could this be an approach that people would call tolerable (as I'm no
C++ programmer at all) ?
Thanks,
Martin.
