solids_on_ray h vSOLIDS_ON_RAY(nged)
NAME
solids_on_ray - list all primitives intersected by a ray through a display point
On this page
SYNOPSIS
DESCRIPTION
The solids_on_ray command fires a ray through the current view from the screen position (h, v) expressed in normalized display coordinates (where 0,0 is the view center) and reports all primitive solids intersected by that ray.
The ray originates from the current view center and travels in the viewing direction at the specified screen offset. All currently displayed objects are tested for intersection.
Both h and v arguments are required; omitting them returns a usage error. Values must be within the valid display bounds.
The output lists the full paths of all primitives hit, in the order they are encountered along the ray.
EXAMPLES
Example 1. Find solids at the center of the view
mged> solids_on_ray 0 0
Fires a ray through the center of the current view and lists all primitive solids along that ray.
Example 2. Find solids at an offset position
mged> solids_on_ray 100 50
Fires a ray 100 units right and 50 units up from the view center and lists the intersected primitives.
