Rect::Intersect

static Rect Intersect(const Rect& a, const Rect& b)

计算两矩形的交集区域。

参数:

  • a - 第一个矩形
  • b - 第二个矩形

返回: Rect - 两矩形的交集,若无交集则返回零尺寸矩形

复杂度: O(1)

示例:

Rect rectA(0.0f, 0.0f, 100.0f, 100.0f);
Rect rectB(50.0f, 50.0f, 100.0f, 100.0f);
Rect overlap = Rect::Intersect(rectA, rectB);  // (50, 50, 50, 50)
