In the ray tracing method of computer graphics a surface can be represented as a set of pieces of planes. The intersection of a ray of light with each plane is used to produce an image of the surface. In vision-based 3D reconstruction, a subfield of computer vision, depth values are commonly measured by so-called triangulation method, which finds the intersection between light plane and ray reflected toward camera.

The equations of the lines are Pa = P1 + u a ( P2 - P1 ) Pb = P3 + u b ( P4 - P3 ) Solving for the point where Pa = Pb gives the following two equations in two unknowns (u a and u b )

NettetYour next choice is to use an alpha shape. In either of the above cases, the outer boundary is a triangulation. So now the problem reduces to solving for the intersection of a line with a triangulated surface. This part is pretty easy. You just need to solve for the intersection of a line with a triangle, and then repeat for each triangle. http://evlm.stuba.sk/~velichova/Geometria/PREDNASKY/prieseca.htm

NettetThe more general problem is intersecting two surfaces. Intersecting a surface and a plane is simpler, but still not easy. There are several possible approaches. One of them is actually quite similar to the technique you mentioned -- dividing the surface into triangles, and intersecting these with the plane to form line segments. NettetIn analytic geometry, the intersection of a line and a plane in three-dimensional space can be the empty set, a point, or a line. It is the entire line if that line is embedded in the …
