用4个顶点计算面法线(Calculating face normals with 4 vertices)
我似乎无法找到用于计算3D中4个顶点平面的法线的等式。 给定4个顶点(x1,y1,z1),(x2,y2,z2)等。我如何计算他们创建的曲面的法线? 我明白它如何与三角形函数一起工作,但我不知道如何将它适应于4个顶点
I can't seem to find what the equation is for calculating the normal of a 4 vertex plane in 3D. Given 4 vertices, (x1, y1, z1), (x2, y2, z2), etc. How do I calculate the normal of the surface they create? I understand how it would work with a triangle shaped function, but I don't know for sure how to adapt it to 4 vertices
