| 3 |  |  | .SH NAME | 
| 4 |  |  | xshowtrace - interactively show rays traced on RADIANCE image under X11 | 
| 5 |  |  | .SH SYNOPSIS |

| 14 |  |  | .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. |

| 37 |  |  | .SH BUGS | 
| 38 |  |  | If the pointer is moved between the time 't' is pressed and | 
| 39 |  |  | .I xshowtrace | 
| 40 |  |  | starts drawing rays, the rays will be displaced. |
