Say you are given the equations of both a line and a curve, for example y=x 2 +8x-1 and y=3x-7, and asked to find where these two intersect. Where the plane can be either a point and a normal, or a 4d vector (normal form), In the examples below (code for both is provided).. Also note that this function calculates a value representing where the point is on the line, (called fac in the code below). Finding the intersection of an infinite ray with a plane in 3D is an important topic in collision detection. But I don’t fully understand how to calculate it on their way. There are three possibilities: The line could intersect the plane in a point. Find intersection line: plane Π 1: + 2+ 3= 5 and plane Π 2: 2−2−2= 2. They may either intersect, then their intersection is a line. Note that this will result in a system with parameters from which we can determine parametric equations from.
