Ray::Intersects (sphere)
bool Intersects(const Sphere& sphere, float& t) const
检测射线是否与球体相交。使用二次方程求根法计算交点。
参数：
sphere- 要检测的球体t- 输出最近交点的参数距离（仅在返回 true 时有效，若射线在球体内部则输出最近的出口点）
返回： bool - 相交返回 true，否则返回 false
线程安全： ✅
复杂度： O(1)
异常： 无
示例：
#include <XCEngine/Core/Math/Ray.h>
#include <XCEngine/Core/Math/Sphere.h>
#include <XCEngine/Core/Math/Vector3.h>
using namespace XCEngine::Math;
Ray ray(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 0.0f, 0.0f));
Sphere sphere(Vector3(10.0f, 0.0f, 0.0f), 1.0f);
float t;
if (ray.Intersects(sphere, t)) {
Vector3 hitPoint = ray.GetPoint(t);
}
