There are other formulas to calculate the bezier<br>
points. I'll check my files to see if I find them.<br>

Can you give us an example of this linear<br>
interpolation?<br>
<br>
By the way jbv, you made a demostration of openGL<br>
in MetaCard. Are you going to keep working in<br>
this demo? or Abandoned the idea?<br>
