|
.SH NAME |
| 4 |
|
gensurf - generate a RADIANCE or Wavefront description of a curved surface |
| 70 |
|
This is most useful as input to the |
| 71 |
|
.I obj2mesh(1) |
| 72 |
|
program for producing a compiled mesh. |
| 73 |
+ |
A single "usemtl" statement will appear at the beginning |
| 74 |
+ |
of the .OBJ output, echoing the modifier given on the command line. |
| 75 |
|
.PP |
| 76 |
|
Rough holes may be cut in the mesh by defining a valid(s,t) function. |
| 77 |
|
Where this function is positive, polygon vertices will be produced. |
| 108 |
|
To generate a 10x20 smoothed height field from 12 recorded vertex |
