   point inside triangle
  I was just wondering what is the best way to determine if a point is inside a triangle.   
  Google for "ray triangle intersection"   ;  If you are talking a point in 2D space being inside of a polygon (triangle or otherwise), check out these links:http://local.wasp.uwa.edu.au/~pbourke/geometry/insidepoly/http://alienryderflex.com/polygon/They're pretty close to the same idea, but I built my system from the second one. Hope that helps.   ;  You would have got the answer by now.If not here it is:http://www.blackpawn.com/texts/pointinpoly/default.html This is the first hit that you get if you Google with your thread title.The solution that uses Barycentric Coordinates is the most efficient one.   ;  Triying to remember trigonometry...I'll do somethink like:Triangle ABC, point T1-Do the cross product of the vector AB and AC. The new one will be a vector normal to the triangle.2-Do the Dot product betwen the normal and AT. If it's 0 they're perpendiculars, then T is in the same plane that the triangle. You can even see if it's up or down watching if it's positive or negative.......Oh... sh**t... inside xDDDDDDD well, I wont delete it 'cause it can be a help for someone...
