swplot.raytriangle

Syntax

swplot.raytriangle(V,F,ray)

Description

swplot.raytriangle(V,F,ray) determines if a given ray crosses within a triangle defined by its vertex coordinates. The code is optimised for a single ray and multiple triangles.

Input Arguments

V

Vertex positions in a matrix with dimensions $[n_{vertex}\times 3]$.

F

Faces in a matrix with dimensions $[n_{face}\times 3]$, where $max(F) = n_{vertex}$.

ray

Definition of the ray via 2 points in space, stored in a matrix with dimensions of $[2\times 3]$. The two points of the ray, $P_1$ and $P_2$, are stored in the first and second rows respectively. The ray points from $P_1$ to $P_2$.
