gluLookAt

GluLookAt is a function commonly used in computer graphics and game development, particularly in the context of OpenGL and similar graphics libraries. It is part of the GLU (OpenGL Utility Library) and is used to define the camera's position and orientation in a 3D scene. The function takes nine parameters, which specify the eye position (x, y, z), the center of the scene (x, y, z), and the up vector (x, y, z). The eye position is the location of the camera, the center is the point in the scene that the camera is looking at, and the up vector defines the orientation of the camera relative to the scene. By calling gluLookAt, the view matrix is set up, which determines how the 3D scene is projected onto the 2D screen. This function is essential for controlling the viewpoint in 3D graphics applications, allowing developers to create interactive and immersive visual experiences.
