我找不到用于找到点与平面之间的有符号距离的一致方法.给定一个定义为点和法线的平面，我该如何计算?

I cannot find a consistent method for finding the signed distance between a point and a plane. How can I calculate this given a plane defined as a point and a normal?

struct Plane { Vec3 point; Vec3 normal; }

推荐答案

您使事情变得太复杂了.如果您的法线正常化，则可以执行以下操作:

You're making things much too complicated. If your normal is normalized, you can just do this:

float dist = dotProduct(p.normal, (vectorSubtract(point, p.point)));
