A point is represented as a dot. It has position only, and has no length, width, or thickness.

A point P is represented by its x, y, and z coordinates.

To access the information relating to a point P, use the following function calls:

The command with(geom3d,point) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{geom3d}\right)\:$

$\mathrm{point}\left(A\,a\,b\,c\right)$

$A$

$\mathrm{form}\left(A\right)$

$\mathrm{point3d}$

$\mathrm{coordinates}\left(A\right)$

$\left[a\,b\,c\right]$

$\mathrm{xcoord}\left(A\right),\mathrm{ycoord}\left(A\right),\mathrm{zcoord}\left(A\right)$

$a,b,c$

$\mathrm{detail}\left(A\right)$

$\begin{array}{ll}\text{name of the object}& A\\ \text{form of the object}& \mathrm{point3d}\\ \text{coordinates of the point}& \left[a\,b\,c\right]\end{array}$
