How to make Triangle to Triangle Intersection Algorithm ??

I see Ray-Triangle Intersection Source Code But I want Triangle-Triangle Intersection Code

I cant make that... Please help or Code Supplement

Your question is not clear. Any pictorial example? More information needed.

Like this One. But This is Three time Ray Intersect in Ray-Triangle Intersection Algorithm

I want Triangle-Triangle intersection Algorithm and, I want know Ray-Triangle n Triangle-Triangle Algorithm have a difference?

Answer 1

[Matt J]

triangle1=polyshape([0 0 ; 1 0; 0 1]);
triangle2=polyshape([0 0 ; 1 0; 1 1]);

p=intersect([triangle1,triangle2]);

tiledlayout(1,2)

nexttile; plot([triangle1,triangle2],'FaceColor','r'); ylim([-0.2,1.2]);
nexttile; plot(p,'FaceColor','r');  ylim([-0.2,1.2]);
