There are no default 3e casters other than psionic classes who use spell points, though. The DM had to go out of his way to convert other caster types to spell points. So spell points did not = spell slots in the default game.In 3e:
Spell slots = Spell points
Slot 1 = 1 point
Slot 2 = 3 points
Slot 3 = 5 points
...
Slot 9 = 17 points
The 3e Psion is a full caster who casts the appropriate spell slots at the appropriate caster levels, from spell slot level 1 spells to spell slot level 9 spells.
