成员函数说明

◆ getDirection()

Vector3d Ray.getDirection ( )

Gets the direction of the ray.

◆ getOrigin()

Vector3d Ray.getOrigin ( )

Gets the origin of the ray.

◆ getPoint()

Vector3d Ray.getPoint ( double t )

Gets the position of a point t units along the ray.

◆ intersects() [1/4]

RayIntersect 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().

◆ intersects() [2/4]

RayIntersect 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().

◆ intersects() [3/4]

RayIntersect 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().

◆ intersects() [4/4]

RayIntersect 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().

◆ IsVertexOn()

boolean Ray.IsVertexOn ( Vector3d vertex )

return true if the vertex is on the ray

◆ setDirection()

void Ray.setDirection ( Vector3d dir )

Sets the direction of the ray.

◆ setOrigin()

void Ray.setOrigin ( Vector3d origin )

Sets the origin of the ray.
