# Defining a plane in R3 with a point and normal vector Linear

Fråga Lund om matematik - Matematikcentrum

So our result should be a line. the same as in the above example, can be calculated applying simpler method. Solution: Intersection of the given plane and the orthogonal plane through the given line, that is, the plane through three points, intersection point B, the point A of the given line and its projection A´ onto the plane, is at the same time projection of the given line onto the given plane, as shows the below figure. Finding the intersection of an infinite ray with a plane in 3D is an important topic in collision detection. Task. Find the point of intersection for the infinite ray with direction (0, -1, -1) passing through position (0, 0, 10) with the infinite plane with a normal vector of (0, 0, 1) and which passes through [0, 0, 5]. Lines that are non-coincident and non-parallel intersect at a unique point.

Determine whether the line x = (− 1, 0, 1) + t (1, 2, 4) intersects the plane 2 x − y + z = 5. Find the point of intersection if they intersect. I know the equation follows the form x = p + t d, so I know which is the point and which is the direction vector. From the general equation of the plane, I know the n is (2, − 1, 1).

The whole task is needed to understand the exercise, so here goes; Basic Equations of Lines and Planes Equation of a Line. An important topic of high school algebra is "the equation of a line." This means an equation in x and y whose solution set is a line in the (x,y) plane.

For this, it suffices to know two points on the line. To find two points on this line, we must find two points that are simultaneously on the two planes, x − z = 1 and y + 2z = 3. Any point on both planes will satisfy x − z = 1 and y + 2z = 3.

To find the intersection of the line and the plane, we usually start by expressing the line as a set of parametric equations, and the plane in the standard form for the equation of a plane. Example \(\PageIndex{8}\): Finding the intersection of a Line and a plane. Determine whether the following line intersects with the given plane. If they do intersect, determine whether the line is contained in the plane or intersects it in a single point. Finally, if the line intersects the plane in a single point, determine this point of

write the line in the form: $$x=-1+t$$ $$y=2t$$ $$z=1+4t$$ and plug this in the equation of the given plane: $$2(-1+t)-2t+1+4t=5$$ from here you will get $$t$$
The intersection of a line and a plane in general position in three dimensions is a point. Commonly a line in space is represented parametrically ( x ( t ) , y ( t ) , z ( t ) ) {\displaystyle (x(t),y(t),z(t))} and a plane by an equation a x + b y + c z = d {\displaystyle ax+by+cz=d} .

We can accomplish this with a system of equations to determine where these two planes intersect. intersections among n line segments in the plane, This time complexity IS easdy shown to be optimal. Within thesame asymptotic cost, ouralgorithm canalso construct thesubdiwslon of theplancdefmed by the segments and compute which segment (if any) lies right above (or below) each intersection and each endpoint. It's the plane that goes through the line 4y minus 3x equals 17, which lies on the xy-plane.
