# NNS_G3dGlbPerspective

## C Specification

      #include <nnsys/g3d/glbstate.h>

      void
      NNS_G3dGlbPerspective(
      fx32 fovySin,
      fx32 fovyCos,
      fx32 aspect,
      fx32 n,
      fx32 f
      );

## Arguments

fovySin | Sine value of the field-of-view angle (view angle) in y-direction/2
fovyCos | Cosine value of the field-of-view angle (view angle) in y-direction/2
aspect | Ratio of width of view field to height of view field (aspect ratio: width/height of the field of view)
n | Distance from eyepoint to the `near` clip plane
f | Distance from eyepoint to the `far` clip plane

## Return Values

None.

## Description
