.SH DESCRIPTION |
| 15 |
|
|
.I Xshowtrace |
| 16 |
|
|
takes a RADIANCE octree and a picture file |
| 17 |
|
|
and displays it on an X11 window server using |
| 18 |
|
|
.I ximage(1). |
| 19 |
|
|
The picture should have been created from a previous |
| 20 |
|
|
.I rpict(1) |
| 21 |
|
|
or |
| 22 |
|
|
.I rview(1) |
| 23 |
|
|
calculation using the given octree. |
| 24 |
|
|
Once the image is displayed, the user can use the 't' command of |
| 25 |
|
|
.I ximage |
| 26 |
|
|
to select points on the image to display the ray tree. |
| 27 |
|
|
.I Rtrace |
| 28 |
|
|
then produces a ray tree, which |
| 29 |
|
|
.I xshowtrace |
| 30 |
|
|
will display (in red on a color screen). |
| 31 |
|
|
The |
| 32 |
|
|
.I \-s |
| 33 |
|
|
option slows the display of each ray traced to make it easier to |
| 34 |
|
|
follow the process. |

|
|
If the pointer is moved between the time 't' is pressed and |
| 39 |
|
|
.I xshowtrace |

starts drawing rays, the rays will be displaced. |
