BoundingFrustum Constructor

  • Article

Creates a new instance of BoundingFrustum.

Namespace: Microsoft.Xna.Framework
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

Syntax

public BoundingFrustum (
         Matrix value
)

Parameters

  • value
    Combined matrix that usually takes view × projection matrix.

Remarks

You can use BoundingFrustum Class to create a bounding volume that corresponds to the space visible to the camera. You create a bounding frustum from the combined view and projection matrix that the camera is using currently. If the camera moves or rotates, you need to recreate the bounding frustum. The bounding frustum isn’t used to determine when two objects collide, but rather when an object is in collision with the volume of space viewable by the camera. Objects that do not intersect and are not contained by the bounding frustum are not visible to the camera and don’t need to be drawn. For complex models, this can save the graphics card a lot of work.
