A frustum is a rectangular pyramid clipped by a near plane and a far plane. When used as a view frustum, the volume within the frustum represents the view of a camera.

The normals for the 6 planes each face out from the frustum, defining its volume. Its coordinates are expressed in meters, and are meaningful in a specific coordinate system usually specified alongside the frustum.


Bottom Bottom Bottom Bottom Bottom

The bottom Plane defines the boundary for the bottommost content within the frustum.

Far Far Far Far Far

The far Plane defines the boundary for the farthest content within the frustum.

Left Left Left Left Left

The left Plane defines the boundary for the leftmost content within the frustum.

Near Near Near Near Near

The near Plane defines the boundary for the closest content within the frustum.

Right Right Right Right Right

The right Plane defines the boundary for the rightmost content within the frustum.

Top Top Top Top Top

The top Plane defines the boundary for the topmost content within the frustum.
