The routine finds the projection Q of an object on the other object.

For a detailed description of the object to be created Q, use the routine detail (e.g., detail(Q))

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

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

$\mathrm{line}\left(l\,\left[\mathrm{point}\left(o\,1\,-1\,3\right)\,\left[2\,-1\,4\right]\right]\right)\:$

$\mathrm{plane}\left(p\,x+2y+z=6\,\left[x\,y\,z\right]\right)\:$

$\mathrm{projection}\left(\mathrm{l1}\,l\,p\right)$

$\mathrm{l1}$

$\mathrm{detail}\left(\mathrm{l1}\right)$

$\begin{array}{ll}\text{name of the object}& \mathrm{l1}\\ \text{form of the object}& \mathrm{line3d}\\ \text{equation of the line}& \left[\mathrm{\_x}=\frac{5}{3}+\frac{4\mathrm{\_t}}{3}\,\mathrm{\_y}=\frac{1}{3}-\frac{7\mathrm{\_t}}{3}\,\mathrm{\_z}=\frac{11}{3}+\frac{10\mathrm{\_t}}{3}\right]\end{array}$
