# swf_perspective

(PHP 4 )

swf_perspective -- Define a perspective projection transformation

## Description

void swf_perspective ( float fovy, float aspect, float near, float far)

The swf_perspective() function defines a perspective projection transformation. The `fovy` parameter is field-of-view angle in the y direction. The `aspect` parameter should be set to the aspect ratio of the viewport that is being drawn onto. The `near` parameter is the near clipping plane and the `far` parameter is the far clipping plane.

> 참고: Various distortion artifacts may appear when performing a perspective projection, this is because Flash players only have a two dimensional matrix. Some are not to pretty.
