Closecamera | The camera with the view frustum that you want to calculate planes from. |
Plane[] The planes that form the camera's view frustum.
Calculates frustum planes.
This function takes the given camera's view frustum and returns six planes that form it.
Ordering: [0] = Left, [1] = Right, [2] = Down, [3] = Up, [4] = Near, [5] = Far

Calculates frustum planes.
This function takes the given camera's view frustum and returns six planes that form it. This is similar to the previous overload, except that instead of allocating a new array for the calculated planes, the function will use an array that you have provided. This array must always be exactly of length 6.

worldToProjectionMatrix | A matrix that transforms from world space to projection space, from which the planes will be calculated. |
Plane[] The planes that enclose the projection space described by the matrix.
Calculates frustum planes.
This function returns six planes of a frustum defined by the given view & projection matrix.
