A third translator, |

The sixth translator, |
| 2524 |
|
.I mgf2meta, |
| 2525 |
|
converts to a 2-dimensional line plot, and is also |
| 2526 |
|
distributed with Radiance. |
| 2537 |
|
In future releases of MGF, this utility will also be handy for |
| 2538 |
|
taking new entities and producing older versions of MGF for |
| 2539 |
|
translators that have not yet been updated properly. |

Mgf2inv converts from MGF to Inventor or VRML format. |
| 2542 |
+ |
Some information is lost, because these formats do not support |
| 2543 |
+ |
physical light sources or materials. |
| 2544 |

.LP |
| 2545 |

3ds2mgf converts from 3D Studio binary format to MGF. |
| 2546 |
+ |
Care must be taken to correct for errors in the material descriptions, |
| 2547 |

since 3D Studio is completely non-physical. |

Since MGF is in its first major release, this is not yet a useful |

LIMITATIONS |
| 2726 |
> |
.LP |
| 2727 |
> |
Obviously, since 3D Studio has no notion of physical materials, the |
| 2728 |
> |
translation to MGF material descriptions is very ad hoc, and it will |
| 2729 |
> |
usually be necessary to edit the materials and light sources in |
| 2730 |
> |
the output file or replace materials with proper entries from a material |
| 2731 |
> |
library using the |
| 2732 |
> |
.I -l |
| 2733 |
> |
option. |
| 2734 |
> |
.LP |
| 2735 |
> |
With smoothing turned on (i.e., a non-zero value for the |
| 2736 |
> |
.I -s |
| 2737 |
> |
option), vertices in the MGF output will not be linked in a proper |
| 2738 |
> |
mesh for each object. |
| 2739 |
> |
This is due to the way the automatic smoothing code was originally |
| 2740 |
> |
written, and is too difficult to repair. |
| 2741 |
> |
If a good mesh is needed, then smoothing must be turned off. |

|
and |
| 4500 |
|
.I nold |

(The two arguments may point to the same vector.)\0 |
| 4503 |
|
No translation or scaling is applied, which is the appropriate |
| 4504 |
|
action for surface normal vectors for example. |
