This example demonstrates the use of the <#8895#>X<#8895#> (intersect) and <#8896#>ON<#8896#> (projection) operators. A triangle with its projection lines is drawn, showing the intersection of the three projection lines trough one point. Again, the coordinates of <#8897#>a<#8897#>, <#8898#>b<#8898#> and <#8899#>c<#8899#> should be judiciously chosen to fit the screen.
The resulting picture looks like:
(315,220)<#8939#>
(010,030)<#8929#>(1,0)<#8902#>240<#8902#><#8929#>
(250,030)<#8930#>(-1,3)<#8903#>060<#8903#><#8930#>
(010,030)<#8931#>(1,1)<#8904#>180<#8904#><#8931#>
Further examples are included with the distributed software.
