.SH DESCRIPTION |
| 35 |
|
.I Gensurf |
| 36 |
< |
produces a RADIANCE scene description of a |
| 37 |
< |
functional surface defined by the parametric equations |
| 36 |
> |
produces either a RADIANCE scene description or a Wavefront .OBJ |
| 37 |
> |
file of a functional surface defined by the parametric equations |
| 38 |
|
.I x(s,t), |
| 39 |
|
.I y(s,t), |
| 40 |
|
and |
| 63 |
|
The |
| 64 |
|
.I \-s |
| 65 |
|
option adds smoothing (surface normal interpolation) to the surface. |
| 66 |
+ |
The |
| 67 |
+ |
.I \-o |
| 68 |
+ |
option produces a Wavefront .OBJ file rather than a RADIANCE |
| 69 |
+ |
scene description. |
| 70 |
+ |
This is most useful as input to the |
| 71 |
+ |
.I obj2mesh(1) |
| 72 |
+ |
program for producing a compiled mesh. |
| 73 |
|
.PP |
| 74 |
|
Rough holes may be cut in the mesh by defining a valid(s,t) function. |
| 75 |
|
Where this function is positive, polygon vertices will be produced. |
| 113 |
|
The smoothing operation requires that functions be defined |
| 114 |
|
beyond the [0,1] boundaries of s and t. |
