title: Triangle - Triangle Intersection Test
body: <p>I'd like to know if there is out there some tutorial or guide to understand and implement a Triangle-Triangle intersection test in a 3D Environment. (i don't need to know precise where the intersection happened, but only that an intersection has occurred)</p>
  
  <p>I was going to implement it following a theoric pdf, but i'm pretty stuck at the </p>
  
  <ol>
  <li>Compute plane equation of triangle 2.</li>
  <li>Reject as trivial if all points of triangle 1 are on same side.</li>
  <li>Compute plane equation of triangle 1.</li>
  <li>Reject as trivial if all points of triangle 2 are on same side.</li>
  <li>Compute intersection line and project onto largest axis.</li>
  <li>Compute the intervals for each triangle.</li>
  <li>Intersect the intervals.</li>
  </ol>
  
  <p>point 5 of this guide. I don't really know what's asking (all 5,6 and 7). XD</p>
  
  <p>As i don't have high knowledge in mathematics (well, i know as far the couple of exams at the university has given me (i'm a raw programmer XD)), please try to be as simple as possible with me. :D (I tried to search on google, but most of the links point to some 4-5 pages full of formulas I don't really care to know and I don't understand.)</p>
  
  <p>Thanks for the help</p>
