NAME

xshowtrace - interactively show rays traced on RADIANCE image under X11

SYNOPSIS

xshowtrace [ -s ][ rtrace options ] octree picture

DESCRIPTION

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.

BUGS

If the pointer is moved between the time `t' is pressed and xshowtrace starts drawing rays, the rays will be displaced.
