Computes the intersection between a line defined by 2 points and a plane defined by a normal and a point on itself. The direction vector l of the line is found easily as the unit cross product of the normals of. We can find the point where line l intersects xy plane by setting z0 in above two equations, we get. Finding the vector equation for a line that intersects two planes linear algebra. To find the equation of the line of intersection between the two planes, we need a point on the line and a parallel vector. If they do intersect, determine whether the line is contained in the plane or intersects it in a single point. Using the cross product and centering the plane on some point, we can put the equation in parametric form. A function to compute the intersection between a parametric line of the 3d space and a plane.

That should be unnecessary if you only care about the line intersecting the plane. It is well known that the line of intersection of an ellipsoid and a plane is an ellipse see for instance 1. We can find the point where line l intersects xy plane. Definition a line in the space is determined by a point and a direction.

Find the intersection of the line through the points 1, 3, 0 and 1, 2, 4 with the plane through the points 0, 0, 0, 1, 1, 0 and 0, 1, 1. Lineplane intersection 3d file exchange matlab central. The fact that we need two vectors parallel to the plane versus one for the line. Some key notions of line geometry are recalled, along with their application to. To find a point on the line, we can consider the case where the line touches the xy plane, that is, where z 0. Lecture 1s finding the line of intersection of two planes. Each surface of the box at the right represents part of a plane. Also, when two lines intersect, we can find the angle between them by finding the smallest angle between their direction vectors using the dot product. How to check line and plane are intersecting and if, how. In analytic geometry, the intersection of a line and a plane in threedimensional space can be.
