The BottomPlane field represents the bottom plane of the frustum, oriented inwards. It is a part of the Frustum structure, which is used to define a 3D space that can be used for various calculations, such as visibility determination and collision detection.
To access the BottomPlane of a Frustum instance, simply use the field directly. This field is public and non-static, meaning it is accessed through an instance of the Frustum struct.
// Example of accessing the BottomPlane of a Frustum Frustum frustum = new Frustum(); Plane bottomPlane = frustum.BottomPlane; // Use the bottomPlane for further calculations or checks Vector3 normal = bottomPlane.Normal; float distance = bottomPlane.Distance;
