The GetBBox method of the Frustum struct returns the axis-aligned bounding box (AABB) that encapsulates the frustum. This method is useful for quickly determining the spatial extent of the frustum in a simplified form, which can be used for broad-phase collision detection or visibility testing.
To use the GetBBox method, you need to have an instance of the Frustum struct. Once you have the instance, simply call the method to retrieve the bounding box:
// Create a frustum instance Frustum frustum = new Frustum(); // Get the axis-aligned bounding box of the frustum BBox boundingBox = frustum.GetBBox(); // Use the bounding box for further processing, such as collision detection // or visibility testing.
