    By convention, in ray-tracing, it is often placed exactly 1 unit away from the camera's origin (this distance will never change and we will explain why further down). By convention, we will also orient the camera along the negative z-axis (the camera default orientation is left to the developer's choice, however generally the camera is oriented along either the positive or the …

    With the help of ray tracing technology, the algorithm draws rays and lines between objects and the camera and works out whether these are visible for the camera and how many pixels each line needs. In addition, ray tracing identifies whether rays of light come from original light sources or from reflected objects in the field of view of the camera.

    Tracing Rays. The next step is to figure out what color the light coming through ( V x, V y, V z) is, as seen from the camera’s point of view ( O x, O y, O z). In the real world, light comes from a light source (the Sun, a light bulb, and so on), bounces off …

Ray tracing (graphics) - Wikipedia

    Ray tracing (graphics) Not to be confused with Ray tracing (physics). This recursive ray tracing of reflective colored spheres on a white surface demonstrates the effects of shallow depth of field, "area" light sources, and diffuse interreflection. In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a ...

Unity - Manual: Rays from the Camera

    https://docs.unity3d.com/Manual/CameraRays.html
    Moving the Camera Along a Ray It is sometimes useful to get a ray corresponding to a screen position and then move the camera along that ray. For example, you may want to allow the user to select an object with the mouse and then zoom in on it while keeping it “pinned” to the same screen position under the mouse (this might be useful when the camera is looking …
