# cross section of a tetrahedron mesh.

I want to find the cross section of tetrahedral mesh. I have developed the partial algorithm.

Follwing are the steps(partial)

Define a plane say ax + by + cz +d =o (n.x = d)
for each tetrahedron in the mesh
for each triangle in the tetrahedron,
Find the point of intersection between the plane and the triangle.
Store intersection points

After this, I have no idea how to proceed.

Can anyone suggest?

The intersection of a plane and a triangle is generally a line segment, not a point.

Those line segments are the edges of polygons.

Does that help?

Yeah, I Know that it is line segment.

But once I get the intersecting line segment,how do I separate, the two sections(meshes).
