         float nearPlaneDistance,
         float farPlaneDistance
)

Parameters

  • left
    Minimum x-value of the view volume at the near view plane.
  • right

  • bottom
    Minimum y-value of the view volume at the near view plane.
  • top
    Maximum y-value of the view volume at the near view plane.
  • nearPlaneDistance
    Distance to the near view plane.
