Hello, i was wondering given a triangle face in 3D space, defined by three corners, for example:
v0(x0, y0, z0), v1(x1, y1, z1), v2(x2, y2, z2).
Find a triangle at plane z = 0, the first corner is (0, 0, 0), have the same shape (same edge length and corner angles) with the triangle in 3D space, how to do that ?
Thank you.
