#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(VIEW_AROLL);
njRotateViewYAbsolute(&v, NJM_DEG_ANG(90));
njSetView( &v );
