This function takes an polygon object, projects it to another $thickness apart, and creates a triangle solid from the two polygons. The triangle is returned as a Lava::Triangulation
.
$tri = Lava::TriSolid_from_Polygon($obj, $thickness, $type)
$obj : polygon object to project and turn into a solid triangulation $thickness : thickness of solid
$type : projection mode (0 = top, 1 = mid, 2 = bottom)
$tri : returned Lava::Triangulation
Example:
my $tri_file = 'C:/Temp/solid.00t';
my $s = new Lava::Selection( 'Select object to triangulate' );
my $tri = Lava::TriSolid_from_Polygon( $s->obj(), 500, 2 );
$tri->write($tri_file);
Lava::Show_Triangulation($tri_file);
This function loads a triangulation (given by $filename) into Vulcan. If $interactive is true then a load panel is displayed, allowing the user to specify the display parameters.
Lava::Show_Triangulation( $filename,$interactive)
$filename : filename of triangulation
$interactive : boolean - show an interactive panel when loading triangulation or use defaults
This function displays the given message in a standard Vulcan text box. The text box is only transitory and will be removed with the next output or input request.
Lava::Show($message)

Lava::Report($message)
$message : Line of text to be displayed.
This function executes a system command and waits for the command to finish before proceeding. It is provided as an alternative to the Perl built-in system function, but unlike system(), will hide any spawned windows in the background. The return value is the exit status of the program as returned by the wait call (see metacpan.org/pod/perlfunc).
Lava::System($command)
$command : system command
This function is an overload of Lava::System, indicated by passing a second parameter, which can be any value. This overloaded version captures STDOUT and sets the return value to it.
Lava::System($command, 1)
$command : system command
