Hi,

assuming you have a monitor with 1920*1080 pixels
how many digits in the difference of two points
can you display in x and y direction (?), 3--4 right ??

Moreover all graphic cards work internal with floats (32 bit).
Only the latest nVidia card are able to use doubles (64 bit)
but not for drawing.

So buy a monitor with more than 192000 *1080000 pixels and
a graphic card the support that resolution.

Regards
   Jens

These data represent the latitude an d longitude of world. So, I need to precisely paint those coordinate in a 3D space as a tiny point, perhaps the method ListPoint3D to be used.However, it seems that ListPoint3D does not support morn than 6 significant digits. So, can anyone help me ?
