xshowtrace - interactively show rays traced on RADIANCE
image under X11
xshowtrace [ -s ][ rtrace options ] octree picture
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.
Greg Ward
If the pointer is moved between the time `t' is pressed and
xshowtrace starts drawing rays, the rays will be displaced.
