Any RADIANCE material descriptions included via one or more |
| 33 |
|
.I \-a |
| 34 |
|
options will be compiled and stored in the mesh as well. |
| 35 |
+ |
If the |
| 36 |
+ |
.I \-l |
| 37 |
+ |
option is used to specify a material file, the RADIANCE library |
| 38 |
+ |
locations are searched. |
| 39 |
|
This mesh may be included in a RADIANCE scene description via the |
| 40 |
|
.I mesh |
| 41 |
|
primitive, thus: |
| 102 |
|
.I obj2mesh. |
| 103 |
|
Normals will be interpolated over the mesh |
| 104 |
|
during rendering to produce a smooth surface. |
| 105 |
< |
If no vertex normals are present, the mess will appear tesselated. |

> |
If no vertex normals are present, the mesh will appear tesselated. |
| 106 |
|
A zero length normal (i.e., 0 0 0) will generate a syntax error. |

This error is caused by too many surfaces, and there is |
| 184 |
|
little hope of compiling this mesh. |
