Vector3::ProjectOnPlane

static Vector3 ProjectOnPlane(const Vector3& vector, const Vector3& planeNormal)

将向量投影到平面上(减去沿平面法线的分量)。

参数:

  • vector - 要投影的向量
  • planeNormal - 平面法线

返回: Vector3 - 平面上的投影向量

复杂度: O(1)

示例:

Vector3 v(1.0f, 1.0f, 1.0f);
Vector3 normal(0.0f, 1.0f, 0.0f);  // XZ 平面
Vector3 projected = Vector3::ProjectOnPlane(v, normal);  // (1, 0, 1)
