分形之闵可夫斯基（Minkowski）

与上一篇文章分形之正方形折线相似，闵可夫斯基分形也是分形出正方体，不同之处是它分出了两个正方体。

核心代码:

static void FractalMinkowski(const Vector3& vStart, const Vector3& vEnd, Vector3* pVertices)
{
    Vector3 vSub = vEnd - vStart;
    Yreal len = D3DXVec3Length(&vSub);

    pVertices[0] = vStart;
    pVertices[8] = vEnd;

    pVertices[4] = (vStart + vEnd)*0.5f;

    pVertices[1] = vStart + vSub*0.25f;
    pVertices[7] = vStart + vSub*0.75f;

    Vector3 v(-vSub.y*0.25f, vSub.x*0.25f, 0.0f);

    pVertices[2] = pVertices[1] + v;
    pVertices[3] = pVertices[4] + v;

    pVertices[5] = pVertices[4] - v;
    pVertices[6] = pVertices[7] - v;
}
