swf_perspective — Define a perspective projection transformation
Description
void swf_perspective
( double
$fovy
, double $aspect
, double $near
, double $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.
Hinweis:
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.
