Ninja Library - View Function

njRotateViewXYZAbsolute

Rotates the view location around the X, Y, and Z axes (absolute rotation)

FORMAT

void njRotateViewXYZAbsolute( *v, angx, angy, angz )
NJS_VIEW *v
Angle angx
Angle angy
Angle angz

PARAMETER

 *v  Pointer to view structure 
 angx  X axis rotation angle (absolute amount) 
 angy  Y axis rotation angle (absolute amount) 
 angz  Z axis rotation angle (absolute amount) 

RETURN

None

DESCRIPTION

Rotates the view by an absolute amount around the X, Y, and Z axes. Rotation proceeds in the order of X axis, Y axis, and Z axis.

EXAMPLE

The following rotates the location of the view located at (0, 0, 3000)
and directed towarded (0, 0, -1) (into the screen) by 30 degrees around the X axis, 
60 degrees around the Y axis and 90 degrees around the Z axis, 
without changing the view location.

#define VIEW_APX 0.f
#define VIEW_APY 0.f
#define VIEW_APZ 3000.f
#define VIEW_AVX 0.f
#define VIEW_AVY 0.f
#define VIEW_AVZ -1.f
#define VIEW_AROLL 0
NJS_VIEW v;
v.apx = VIEW_APX;
v.apy = VIEW_APY;
v.apz = VIEW_APZ;
v.avx = VIEW_AVX;
v.avy = VIEW_AVY;
v.avz = VIEW_AVZ;
v.aroll = NJM_DEG_ANG(AVIEW_ROLL);
njRotateViewXYZAbsolute(&v, NJM_DEG_ANG(30), NJM_DEG_ANG(60), NJM_DEG_ANG(90));
njSetView( &v );

NOTE

When argument v is NULL, the current view is rotated.
