Bounds和Rect的区别

Bounds: 表示的是长方体, 用center和extends(halfSize)表示
Rect: 表示二维矩形, 用左下角和size表示

 

根据min, max创建Bounds

写法1:

public static Bounds GetBounds(Vector3 vMin, Vector3 vMax)
{
    var bounds = new Bounds(vMin, Vector3.zero);
    bounds.Encapsulate(vMax); //会调整center和extends
    return bounds;
}

写法2:

public static Bounds GetBounds(Vector3 vMin, Vector3 vMax)
{
    var bounds = new Bounds();
    bounds.Encapsulate(vMin);
    bounds.Encapsulate(vMax);
    return bounds;
}
