ssdfasd 63d0271a5b Fix broken links in Math API docs
Fix 30+ broken cross-references in docs/api/math/:
- viewport: viewport-getaspectratio/getrect -> getaspectratio/getrect
- matrix4: ../color/operator-mul -> operator_mul, operator-index -> operator_index
- matrix4/get-*: gettranslation/getscale/getrotation -> get-translation/-scale/-rotation
- vector3 operator links: operator_*_assign -> operator-*-assign
- vector3 operator links: operator_sub/add -> operator-sub/add
- vector3 operator-eq/neq: swap mutual references to use hyphen naming
- vector4: ../plane/constructor-default -> constructor_default
- Linter fixes: aabb and rectint relative paths corrected

Viewport

渲染视口结构体,用于屏幕到归一化坐标的映射。

头文件: #include <XCEngine/Math/Rect.h>

命名空间: XCEngine::Math

结构体定义

struct Viewport {
    float x = 0.0f;
    float y = 0.0f;
    float width = 0.0f;
    float height = 0.0f;
    float minDepth = 0.0f;
    float maxDepth = 1.0f;

    Viewport() = default;
    Viewport(float x, float y, float w, float h);
    Viewport(float x, float y, float w, float h, float minD, float maxD);
};

构造函数

方法 描述
Viewport() 默认构造
Viewport(x, y, w, h) 2D 视口
Viewport(x, y, w, h, minD, maxD) 带深度范围的 3D 视口

方法

方法 返回值 描述
GetAspectRatio() float 宽高比 (width / height)
GetRect() Rect 转换为 Rect
