You need to be more clear with what you are doing so people can help..

If you don't want distance perspective effects then you need to not use a 3D coordinate system, which as modus alludes to, is effectively getting rid of one dimension.

Have you looked into Orthographic Projections?

i need z value to vary...(as its one of the requirements)

n i also need perspective only cos once whole grid is complete i have 2 display it from various views..(top view, fly through...)

the number of points is very large. it creates an effect of some geographical map showing peaks,valleys type area..

(i hope i am more clear now in explainin my problem)

Do not draw points, but draw a quad between 4 points.
