John-
PVWave has a group of canned routines in $WAVE_DIR/lib/user.
In it you will find one called plot3d.pro. I used this just
the other day and it work fairly well. I had found I was
limited to approx. 3000 x,y,z triplets but it gave me what
I wanted.

Try PLOT3d in conjunction with keyword PSYM:
Idl_vs:
Idl_vs: x = indgen(20)
Idl_vs: y = indgen(20)
Idl_vs: z = x*y
Idl_vs: window,/free,xs=512,ys=512
Idl_vs: plot3d, x, y, z, psym=5
Idl_vs:
