intersection_packet_t castRays( const SolidTree_ExtTriangle & tree,
  const std::vector< ray_t > & rays,
  const box_t & bounds
)    

Cast a packet of rays against a scene and return the first objects that are hit together with the intersection distance.

Parameters

scene
Root node of the scene that will be used for casting
rays
Array of rays, given in the world coordinate system

Returns

Array of intersection results. Each result contains the first object that is hit by the ray, ornullptrif no object is hit, as first entry. The intersection value for the point where an object is hit is stored in the second entry of the result.
