Web11 de abr. de 2024 · 可通过投影矩阵 projection matrix 创建一个观察盒（viewing box）被称为视锥体（frustum），在视锥体之外的坐标会被剪裁（clip），如果一个图元（例如三角形）的一部分位于裁剪体积之外，OpenGL 将重构该基元，将其拆分为一个或多个三角形以适应裁剪范围内。 WebThe view matrix takes three arguments, all three as three-vectors: glm::lookAt (position, focus, up);. The first argument is the position of the camera, the second argument is the focus of the camera (i.e. at which point in space the camera is looking at) and the final argument is the up direction. sonix trucking
