Check if point is in triangle
WebThe intersection of these three half-planes is the interior of the triangle. So all you have to do is check whether (2,18) satisfies all three to find out if it lies inside the triangle. It obviously satisfies the first two, so you just … WebDec 7, 2024 · What we do first is use point P’s Barycentric coordinates to interpolate the values of the red triangle: 002, 011, 101 to get point A. You treat those values as if they are at the corners of the larger triangle (if you think about it, this is how quadratic Bezier curves work too with the time parameter.
