Often, objects lie on the boundary of the viewing frustum.
Values outside of this range correspond to points which are not in the viewing frustum, and shouldn't be rendered.
Objects not within the view frustum are not visible.
The viewing frustum is a geometric representation of the volume visible to the virtual camera.
Some authors use pyramid of vision as a synonym for view frustum itself, i.e. consider it truncated.
Objects that intersect the boundaries of the viewing frustum are clipped (partially drawn).
Geometric primitives that now fall completely outside of the viewing frustum will not be visible and are discarded at this stage.
This viewport is defined by the geometry of the viewing frustum, and parameterizes the field of view.
In beam tracing, a pyramidal beam is initially cast through the entire viewing frustum.
Distributing contiguous 2D tiles of pixels allows for data scaling by culling data with the view frustum.
If the ray or viewing frustum does not intersect the bounding volume, it cannot intersect the object contained within.
The viewing frustum in 3D computer graphics is a virtual photographic or video camera's usable field of view modeled as a pyramidal frustum.
View frustum culling is the process of removing objects that lie completely outside the viewing frustum from the rendering process.
In ray tracing, bounding volumes are used in ray-intersection tests, and in many rendering algorithms, they are used for viewing frustum tests.
The cube map is generated by first rendering the scene six times from a viewpoint, with the views defined by an 90 degree view frustum representing each cube face.
Each eye's position also serves to specify that eye's frustum since the eye's position relative to a Screen3D uniquely specifies that eye's view frustum.
Space partitioning is also often used in scanline algorithms to eliminate the polygons out of the camera's viewing frustum, limiting the number of polygons processed by the pipeline.
This should be accompanied by a viewing frustum that has a far clipping plane that extends to infinity in order to accommodate those points, accomplished by using a specialized projection matrix.
The WebGL API may be too tedious to use directly without some utility libraries, which for example set up typical view transformation shaders (e.g. for view frustum).
A common technique, reflection mapping, can optionally use existing occlusion estimates from the viewpoint of the main view frustum; or, if performance allows, a new occlusion map can be computed from a separate camera position.
Actors are kept in their own scene partitioning data structure from which their visibility is tested against the view frustum and from which eventually they are extracted at rendering time to be part of the rendering queue.
Quake's software rasterizer used surface caching to apply lighting calculations in texture space once when polygons initially appear within the viewing frustum (effectively creating temporary 'lit' versions of the currently visible textures as the viewer negotiated the scene).
The term is commonly used in computer graphics to describe the three-dimensional region which is visible on the screen, the "viewing frustum", which is formed by a clipped pyramid; in particular, frustum culling is a method of hidden surface determination.
In 3D computer graphics, the view frustum (also called viewing frustum) is the region of space in the modeled world that may appear on the screen; it is the field of view of the notional camera.
At the start of a new scene, the z-buffer must be cleared to a defined value, usually 1.0, because this value is the upper limit (on a scale of 0 to 1) of depth, meaning that no object is present at this point through the viewing frustum.

The use of portals simplifies the game engine's task of determining visible areas and objects from any given point of view of the level, and simplifies rendering by allowing it to use each portal as a viewing frustum for the area it leads to.
