Can someone tall me how to make an object move along a helical path, prefereably around the Y axis, in terms of glTranslate? This would be very much appreciated.

a helix is a cirular path moving in a third dimension, so you could do something like:

x=cos(A*t);
y=B*t;
z=sin(A*t);
glTranslatef( x, y, z);

where A and B are constants, and t is time (and hence increases)

hope that helps!

To simplify that it is just an object moving on a circular path (on the x-z axis), then you just increase y every frame to make upwards (helical) movement. I think that''s right...
