left | The X coordinate of the left side of the near projection plane in view space. |

right | The X coordinate of the right side of the near projection plane in view space. |

bottom | The Y coordinate of the bottom side of the near projection plane in view space. |

top | The Y coordinate of the top side of the near projection plane in view space. |

zNear | Z distance to the near plane from the origin in view space. |

zFar | Z distance to the far plane from the origin in view space. |

frustumPlanes | Frustum planes struct that contains the view space coordinates of that define a viewing frustum. |

**Matrix4x4**
A projection matrix with a viewing frustum defined by the plane coordinates passed in.

This function returns a projection matrix with viewing frustum that has a near plane defined by the coordinates that were passed in.

The corners of the near plane of the viewing frustum of the projection matrix are as follows:

top-left : (left, top, zNear)

top-right : (right, top, zNear)

bottom-right : (right, bottom, zNear)

bottom-left : (left, bottom, zNear)
