"網頁A pyramid-shaped volume (the frustum of vision) shows the side-to-side and _top-to-bottom boundaries of the scene — objects outside this volume are not seen. They are said to be "clipped" by the sides of the frustum. So far, this corresponds with the way a real camera works; a zoom lens just changes the angular size (or width) of that frustum ...

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 a perspective virtual camera system. The view frustum is typically obtained by taking a frustum—that is a truncation with parallel planes—of the pyramid of vision, which is the adaptation of (idealized) cone of vision that a camer… 網頁2024年10月16日 · fed0r July 9, 2014, 2:58pm 3. Sorry for being so obvious, but you might try tracing from each actor position to your POV (camera position), then checking if the trace was unsuccessful (nothing occludes the visibility) and it lays within the frustum cone. This is an ugly hack, I might guess, but I am not familiar with Unreal’s graphical pipeline.

網頁Understanding the View Frustum. The word frustum refers to a solid shape that looks like a pyramid with the top cut off parallel to the base.
