  1. Uso de MEL (Maya Embedded Language) Para: Números aleatorios Fractales

  2. Abrir MEL

  3. MEL (Maya Embedded Language) • En el Script Editor. • File -> Open (O copiar y pegar el script en la parte de abajo del Script Editor). • Seleccionar la parte del texto a ejecutar y oprimir el botón: • Practicar con el script: “Aleatorios.mel”

  4. Aleatorios.mel sphere; rename nurbsSphere1 a1; select a1; duplicate -rr; for($i=1; $i<=9; ++$i) duplicate -rr -st; for($i=1; $i<=10; ++$i) { select("a"+$i); $x=rand(-5,5); print $x; print " "; $y=rand(1,10); print $y; print " "; $z=rand(-5,5); print $z; print "\r"; move $x $y $z; select -d; }; for($i=1;$i<=10;$i++) { $x = rand(1,1000); select ("a"+$i); rotate $x $x $x; select -d; };

  5. Aleatorios.mel
