GeometryUtility.CalculateFrustumPlanes

Parámetros

Valor de retorno

Plane[] The planes that form the camera's view frustum.

Descripción

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

Descripción

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.

Ordering: [0] = Left, [1] = Right, [2] = Down, [3] = Up, [4] = Near, [5] = Far
