成员函数说明

RayIntersect AnyCAD.Foundation.Ray.intersects ( AABox box )

Tests whether this ray intersects the given box.

返回: A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().

RayIntersect AnyCAD.Foundation.Ray.intersects ( BoundedVolumeD p )

Tests whether this ray intersects the given plane bounded volume.

返回: A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().

RayIntersect AnyCAD.Foundation.Ray.intersects ( Plane p )

Tests whether this ray intersects the given plane.

返回: A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().

RayIntersect AnyCAD.Foundation.Ray.intersects ( Sphere s )

Tests whether this ray intersects the given sphere.

返回: A pair structure where the first element indicates whether an intersection occurs, and if true, the second element will indicate the distance along the ray at which it intersects. This can be converted to a point in space by calling getPoint().
