.SH DESCRIPTION |
| 15 |
|
|
.I Bsdfview |
| 16 |
|
|
renders a BSDF description interactively. |
| 17 |

This is a script that creates a rad input file (RIF) |
| 18 |
greg |
1.1 |
then calls |
| 19 |
|
|
.I rad(1) |
| 20 |
greg |
1.2 |
to make an octree via |
| 21 |
|
|
.I bsdf2rad(1), |
| 22 |
|
|
then views the scene interactively. |
| 23 |
greg |
1.1 |
.PP |
| 24 |
|
|
The input is either a single XML file, such as might be produced by |
| 25 |
|
|
.I genBSDF(1), |
| 26 |
|
|
.I bsdf2klems(1), |
| 27 |
|
|
or |
| 28 |
|
|
.I bsdf2ttree(1), |
| 29 |
greg |
1.2 |
or up to four scattering interpolation representation (SIR) files, as |
| 30 |
greg |
1.1 |
might be produced by |
| 31 |
|
|
pabopto2bsdf(1). |
| 32 |
|
|
.PP |
| 33 |
|
|
A rad input file will be produced, whose name matches the root of |
| 34 |
|
|
the first input file but with any leading path removed (i.e., in |
| 35 |
|
|
the current directory). |
| 36 |
|
|
This RIF may be reused for subsequent viewing and rendering via |
| 37 |
|
|
.I rad |
| 38 |
|
|
without incurring the cost of another call to |
| 39 |
|
|
.I bsdf2rad. |
| 40 |
|
|
.PP |
| 41 |
|
|
The quality preference may be set via the |
| 42 |
|
|
.I \-q |
| 43 |
|
|
option. |
| 44 |
|
|
The number of processors to use may be specified with the |
| 45 |
|
|
.I \-n |
| 46 |
|
|
option. |
