The InsideTriangle method determines if a given point p lies inside a triangle defined by three vertices a, b, and c. The method also considers the normal vector of the triangle's plane, normal, to ensure the point is within the triangle's plane.
Use this method when you need to check if a point is inside a specific triangle in 3D space. This can be useful for collision detection, hit testing, or other geometric calculations involving triangles.
Vector3 a = new Vector3(0, 0, 0); Vector3 b = new Vector3(1, 0, 0); Vector3 c = new Vector3(0, 1, 0); Vector3 p = new Vector3(0.25f, 0.25f, 0); Vector3 normal = Vector3.Cross(b - a, c - a).Normalized(); bool isInside = PolygonMesh.InsideTriangle(a, b, c, p, normal); // isInside will be true if point p is inside the triangle formed by a, b, and c.
