We can reparametrize the coordinates of the vertices of X to be in line with this edge: p_i is the distance the i-th vertex of X is away from the edge, with some other coordinate q_i. If p_i is positive then the vertex of X lies on the same side of the edge as Y. If we repeat this for each of the edges of Y and p_i is positive for all of the edges, then the vertex of X must lie inside Y. $p_i$ is the distance the i-th vertex of X is away from the edge, with some other coordinate $q_i$. If $p_i$ is positive then the vertex of X lies on the same side of the edge as Y. If we repeat this for each of the edges of Y and $p_i$ is positive for all of the edges, then the vertex of X must lie inside Y. If some p_i are positive and some negative then there are intersections between this edge of Y and those of X. If some $p_i$ are positive and some negative then there are intersections between this edge of Y and those of X. Therefore, by discovering which vertices of X lie inside Y we have determined which edges of X intersect which edges of Y.} \begin{figure} ... ... @@ -434,7 +434,7 @@ Now the sign of the numerator defines which side of the vertex of Y the face of \note{ How can we apply this to higher dimensions? Suppose we now have the n-simplex with unit edges that align with the coordinate axes, which denote by vectors e eta. Suppose we intersect this with another n-simplex with vertices at the points x_i for n+1 values of i. Suppose we intersect this with another n-simplex with vertices at the points $x_i$ for n+1 values of i. At a given step in the algorithm we need to know the intersection between an m-dimensional `face' of X and m hyperplanes of Y. This intersection can be written as this quotient. The numerator of this quotient is shared over m of these intersections, keeping the given m-face of X constant but changing the m hyperplanes. ... ...
