The part of a solid next the base, formed by cutting off the, top; or the part of any solid, as of a cone, pyramid, etc., between two planes, which may be either parallel or inclined to each other.

The part of a solid cone or pyramid next to the base that is formed by cutting off the top by a plane parallel to the base

The visible volume between the near and far clipping planes

a truncated cone or pyramid; the part that is left when a cone or pyramid is cut by a plane parallel to the base and the apical part is removed

a definition of the volume that determines which objects are visible (within the camera view) and which are not

a solid whose base and top faces are similar (i

The viewing frustum for a Camera defines the volume of 3D space that is rendered. This is defined in terms of a front clipping distance, a far clipping distance and the rectangle at the front clipping distance. P01

The view volume warped by perspective division.

Computer-generated objects can be projected into an artificial viewing area, called a frustum. A frustum is in the form of a truncated pyramid, shown in Figure 5-3, between the base of the viewing volume, called the far plane, and the near plane.

The portion of a regular solid left after cutting off the upper part by a plane parallel to the base; or the portion intercepted between two planes, either parallel or inclined to each other.

the basal part of a solid cone or pyramid formed by cutting off the top by a plane parallel to the base; the part of a solid intersected between two usually parallel planes

In 3D programming: A pyramid-like shape with its point at the 'camera', pointing in the direction that you are viewing, and the base representing the far clip plane. This geometric shape contains all objects that are visible.

In GL, a truncated, four-sided pyramid; that is, a pyramid with the point cut off. In a perspective projection, the shape of the clipping volume is a frustum. The bottom of the frustum is referred to the far clipping plane, the top of the frustum is the near clipping plane, and the sides are respectively the top, left, bottom, and right clipping planes. In an orthographic projection, the clipping volume is a parallelepiped.

1. The solid figure that is created when the top of a cone is cut off parallel to the base. 2. Column that has been cut shorter.

A frustum is the portion of a solid – normally a cone or pyramid – which lies between two parallel planes cutting the solid. Degenerate cases are obtained for finite solids by cutting with a single plane only.
