サンプル

Raycaster.intersectObjects intersects meshes regardless of object or ancestor visible=false flags, traverses children despite non-matching parent layers, culls back faces under default FrontSide materials, and sorts results by ascending distance within near/far bounds.

よくある思い込み

Raycaster ignores invisible objects or their children and halts recursive descent through parent objects whose layer masks do not match the raycaster.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• Raycaster.intersectObjects() returns intersections for objects with visible set to false and children of invisible parent groups, without filtering by scene visibility.
• Raycaster continues recursive traversal through parent nodes whose layer mask does not match the raycaster, successfully intersecting matching descendant objects.
• Raycaster culls back-facing triangles by default when material.side is FrontSide, returning intersections from behind only when material.side is DoubleSide.
• Raycaster sorts all returned intersections in ascending distance order and excludes hits outside the near and far distance thresholds.
• Raycaster intersects Points within params.Points.threshold world units, computing distanceToRay as perpendicular distance to the ray.
