Now I have drawn a triangle mesh. (The function to generate image I use are as follows. )I want to ask for the intersection point, as shown in the figure(Red line with the mesh). But I don't know how to solve it.
PS:You can define the expression of a line at will,like "x=5".
If you want, I have some expression here.
trimesh(face', vertex(1,:), vertex(2,:), vertex(3,:),'LineWidth',1,'EdgeColor','k');hold off;vertex0=vertex';V=vertex0(:,1:2);x1=V(:,1);y1=V(:,2);z1=repmat(-20,1380,1);tr = triangulation(face',x1,y1,z1); %x1.y1.z1 is a set of three coordinates of vertices
trimesh(tr);axis equal;colorbar('vert');brighten(-0.1);axis on; % 'face' is the index list of triangle patch vertices;'vertex' is the index list of triangle vertex coordinates.
