Rotates a light matrix around the Y axis.

FORMAT

#include <NINJA.H> 
void njRotateLightY( *ptr, angy )
NJS_LIGHT *ptr
Angle angy

PARAMETERS

*ptr
light pointer
angy
angle of rotation around Y axis

RETURN VALUE

None

ERROR VALUE

None

FUNCTION Rotates a light matrix defined with njCreateLight around the Y axis. This results in calculation of the light source position and direction.

EXAMPLE

#include <NINJA.H> 
...........
      
NJS_LIGHT light;

njInitSystem();
njCreateLight(&light, NJD_POINT_LIGHT);

...........
njClearMatrix();

/* Rotate 60 degrees around Yaxis */
njRotateLightY(&light, NJM_RAD_ANG(NJD_PI/3.f));

NOTES Before calling this function, the light to be modified must be specified by njCreateLight and njClearMatrix must be called.
