|
|
|
||
|
|
```cpp
|
||
|
|
Ray(const Vector3& origin, const Vector3& direction)
|
||
|
|
```
|
||
|
|
|
||
|
|
从起点和方向构造射线。
|
||
|
|
|
||
|
|
**参数：**
|
||
|
|
- `origin` - 射线起点
|
||
|
|
- `direction` - 射线方向（构造时会被归一化）
|
||
|
|
|
||
|
|
**返回：** 无
|

|
|
||
|
|
```cpp
|
||
|
|
#include <XCEngine/Math/Ray.h>
|
||
|
|
#include <XCEngine/Math/Vector3.h>
|
||
|
|
|
||
|
|
using namespace XCEngine::Math;
|
||
|
|
|
||
|
|
Ray ray(Vector3(0.0f, 0.0f, 0.0f), Vector3(1.0f, 0.0f, 0.0f));
|
||
|
|
// direction 已被归一化
