.SH DESCRIPTION |
| 17 |
.I Xshowtrace |
| 18 |
takes a RADIANCE octree and a picture file |
| 19 |
and displays it on an X11 window server using |
| 20 |
.I ximage(1). |
| 21 |
The picture should have been created from a previous |
| 22 |
.I rpict(1) |
| 23 |
or |
| 24 |
.I rvu(1) |
| 25 |
calculation using the given octree. |
| 26 |
Once the image is displayed, the user can use the 't' command of |
| 27 |
.I ximage |
| 28 |
to select points on the image to display the ray tree. |
| 29 |
.I Rtrace |
| 30 |
then produces a ray tree, which |
| 31 |
.I xshowtrace |
| 32 |
will display (in red on a color screen). |
| 33 |
The |
| 34 |
.I \-s |
| 35 |
option slows the display of each ray traced to make it easier to |
| 36 |
follow the process. |
| 37 |
The |
| 38 |
.I \-T |
| 39 |
option traces rays to light sources, which are normally hidden. |

.SH BUGS |
| 43 |
If the pointer is moved between the time 't' is pressed and |
| 44 |
.I xshowtrace |
| 45 |
starts drawing rays, the rays will be displaced. |
