    Study Notes

    Understanding the Pyramid of Vision in 3-D Environments

    • The pyramid of vision, also known as the cone of vision, is the portion of the 3-D environment seen through the camera.
    • It is defined by parameters like the point of view, point of interest, line of sight, near and far clipping planes, field of vision, viewing angle, focal length, and depth of field.
    • The point of view is the camera's location, and the point of interest is the focus point in space.
    • Clipping planes, including the near and far clipping planes, define the visible area and the field of vision.
    • The focal length of a camera determines how 3-D objects are seen and can be simulated virtually.
    • Depth of field refers to the portion of the scene in front of the camera that appears focused and can be used to direct the viewer's attention.
    • Different camera lenses, with varying focal lengths, can be used for practical and stylistic purposes in 3-D rendering software.
    • Lenses with short focal lengths offer a wide angle of view and increased depth of field, while longer focal lengths have a narrow angle of view and depth of field.
    • The camera has a powerful storytelling effect and can be animated to guide the audience through visual storytelling.
    • Camera moves based on changes in position include dolly, truck, and boom, while moves based on orientation changes include tilt, roll, and pan.
