| Public method | RayIntersections(Point rayOrigin, Point rayDirection) | Finds the intersections between this MeshGeometry and a ray. |
| Public method | RayIntersections(System.Double x, System.Double y) | Finds the intersections between this MeshGeometry and a vertical ray at the specified position. |
RayIntersections(Point rayOrigin, Point rayDirection)
Finds the intersections between this MeshGeometry and a ray.Syntax
public PointCollection RayIntersections (
Point rayOrigin,
Point rayDirection
)Parameters
rayOrigin
Type: Point
Origin of the ray.
Origin of the ray.
rayDirection
Type: Point
Direction vector of the ray.
Direction vector of the ray.
Remarks
Finds the points on this geometry intersecting a ray defined by an origin and direction in the model's coordinates. Points are ordered from closest to farthest from the origin of the ray. A direction of (0, 0, 0) will not create any intersections.
RayIntersections(System.Double x, System.Double y)
Finds the intersections between this MeshGeometry and a vertical ray at the specified position.Syntax
public PointCollection RayIntersections (
System.Double x,
System.Double y
)Parameters
x
Type: System.Double
X coordinate of the ray.
X coordinate of the ray.
y
Type: System.Double
Y coordinate of the ray.
Y coordinate of the ray.
Remarks
A method that uses a vertical ray to get the intersecting points along the Z axis at the given position. Returned points are ordered with the highest Z value first.
