# MTX_Perspective

## Syntax

      #include <nitro/fx/fx_mtx44.h>

      void MTX_Perspective(
          fx32 fovySin,
          fx32 fovyCos,
          fx32 aspect,
          fx32 n,
          fx32 f,
          MtxFx44 * mtx
      );

## Arguments

fovySin | Sine value of (the field-of-view angle in y-direction)/2
fovyCos | Cosine value of (the field-of-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 viewpoint to the near clipping plane
f | Distance from viewpoint to the far clipping plane
mtx | Pointer to a 4x4 matrix.

## Return Values

None.

## Description

*This function sets a perspective projection matrix to *mtx.
The diagram shows the matrix that is set.

The divider is used internally. Refer to Divider Usage Notes when using this function inside an interrupt.
