<scene>.intersect

This command checks if the specified line segment intersects with any objects in the scene. It will return a viz.Intersect object containing info about the intersection results.

Nodes that have viz.INTERSECTION disabled will not appear in the results.

Intersection tests can be optimized for certain nodes by using the viz.OPTIMIZE_INTERSECT_HINT flag with the <node3d>.hint command. This hint can significantly increase memory usage though.

The return value is a viz.Intersect object or a list of viz.Intersect objects if parameter all is true.

The following is a list of fields of the viz.Intersect object:

Attribute
valid	True if an intersection occurred, False if it didn't.
point	The point of intersection with the object.
normal	The normal vector of the intersect point.
object	The node3d object that was intersected. This will be the lowest level node3d object within the scene hierarchy. You can prevent specific nodes from appearing as the intersect object by disabling viz.INTERSECT_INFO_OBJECT on them. In this case, the first parent node with this attribute enabled will be reported as the intersect object.
name	The name of the sub-node that was intersected.
object_path	A list of node3d objects representing the full path to the intersected object within the scene hierarchy. This value is only computed if the computePath option is True.
name_path	A list of sub-node names representing the full path to the intersected object within the scene hierarchy. This value is only computed if the computePath option is True.
