function

intersection_packet_t castRays( GroupNode * scene,
  const std::vector< ray_t > & rays
)    

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.

function
MinSG::RayCasting::RayCaster::castRays

public static
     
     
intersection_packet_t castRays( GeometryNode * geoNode,
  const std::vector< ray_t > & rays
)    

Cast a packet of rays against a single object and check if the object is hit.

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 object if it is hit by the ray, ornullptrif it is not hit, as first entry. The intersection value for the point where the object is hit is stored in the second entry of the result.
