Xshowtrace takes a RADIANCE octree and a picture file
and displays it on an X11 window server using
ximage(1). The picture should have been created from
a previous rpict(1) or rview(1) calculation
using the given octree. Once the image is displayed, the
user can use the 't' command of ximage to select
points on the image to display the ray tree. Rtrace
then produces a ray tree, which xshowtrace will
display (in red on a color screen). The -s option
slows the display of each ray traced to make it easier to
follow the process. |
