Seeking for 3D library in C

[monsak]

Hi all;

I have a data in (x,y,z), floating point, generated from C and i want to
plot this data in 3D world. Does any one know some kind of library, in
C, that i can use it directly in my program to generate the 3D graphics.
If i have to write my own routine for this, how can i do it. So far i
know how to write a pixel and line, but i'm still confused how to change
my data to an integer. What i understand is when plotting pixel i have
to use the integer, but my data is not. So please give me some
suggestion on this.

regards,
monsak
