◆ V3D_TO_V2D

#define V3D_TO_V2D (   v3,
  v2,
  width,
  height,
  distance 
)
Value:
{ \
int Xp; \
int Yp; \
if ((v3).z > 2) { \
F2I(((distance) * (v3).x / (v3).z),Xp) ; \
F2I(((distance) * (v3).y / (v3).z),Yp) ; \
(v2).x = Xp + ((width)>>1); \
(v2).y = -Yp + ((height)>>1); \
} \
else (v2).x=(v2).y=-666; \
}

◆ Y_ROTATE_V3D

#define Y_ROTATE_V3D (   vi,

(vf).x = (vi).x * (cosa) - (vi).z * (sina);\
(vf).z = (vi).x * (sina) + (vi).z * (cosa);\
(vf).y = (vi).y;\
}
