视角投影（Perspective Projection）的详细解释
一、基本定义 视角投影是一种在二维平面上模拟人眼观察三维空间物体时产生的视觉效果的技术。其核心在于模仿光线从物体表面反射后通过一个“视点”（类似于人眼瞳孔）投射到成像平面（类似于视网膜）的过程。这种投影会导致物体随着与视点距离的增加而呈现“近大远小”的视觉收缩现象，并产生“消失点”（所有平行线在远处汇聚的点），从而在二维平面上营造出深度感和空间立体感。它是计算机图形学、摄影、建筑制图等领域中实现真实感三维渲染的核心技术。
二、核心原理与数学表达
三、关键特征
四、应用领域

Perspective projection（透视投影）是计算机图形学中用于将三维物体转换为二维图像的核心技术，其特点是模拟人眼的视觉规律，使远处的物体比近处的物体更小，从而呈现立体感和空间深度。
基本原理
通过将三维坐标系中的点沿着视线方向投影到虚拟的二维平面上，投影后的位置会根据物体到观察点（如相机）的距离（通常由z轴坐标决定）动态缩放。例如，一个立方体的远顶点在投影后坐标会被压缩，形成「近大远小」的效果。
数学表达
使用齐次坐标和投影矩阵实现变换。标准透视投影矩阵公式如下：
$$
begin{bmatrix}
frac{2n}{r-l} & 0 & frac{r+l}{r-l} & 0
0 & frac{2n}{t-b} & frac{t+b}{t-b} & 0
0 & 0 & -frac{f+n}{f-n} & -frac{2fn}{f-n}
0 & 0 & -1 & 0
end{bmatrix}
$$
其中，(n)和(f)为近/远裁剪面距离，(l, r, t, b)为投影平面左右上下的边界。投影后坐标需通过透视除法（除以w分量）得到标准化设备坐标（NDC）。
与正交投影的区别
若需更深入的技术实现细节（如具体API调用），建议参考计算机图形学教材或OpenGL/DirectX文档。
