Now trying this: Point-Line Distance, where x0 is the point, and x1 and x2 make up the line.

x0 = camera
x1 = player model
x2 = help point (left/right of player model along the right-vector of the camera)

|(x0 - x1) X (x0 - x2)|      <- *
-----------------------
       |x2 - x1|

*) u X v = ((uy*vz - uz*vy), (uz*vx - ux*vz), (ux*vy - uy*vx))

Another failed attempt (just copying it here because it made it into no commit):

d[0] = subf(MEM_ReadInt(_@(her)+72), MEM_ReadInt(MEM_Camera.connectedVob+72));
d[1] = subf(MEM_ReadInt(_@(her)+88), MEM_ReadInt(MEM_Camera.connectedVob+88));
d[2] = subf(MEM_ReadInt(_@(her)+104), MEM_ReadInt(MEM_Camera.connectedVob+104));
const int zMAT4__Rotate = 5542544; //0x549290
CALL_PtrParam(_@(d));
CALL_RetValIsStruct(12);
CALL__thiscall(MEM_Camera.connectedVob+60, zMAT4__Rotate);
var int dPtr; dPtr = CALL_RetValAsInt();
MEM_CopyWords(dPtr, _@(d), 3);
MEM_Free(dPtr);

d[0] = FLOATNULL;
var int dist; dist = sqrtf(addf(addf(sqrf(d[0]), sqrf(d[1])), sqrf(d[2])));

d[0] = addf(MEM_ReadInt(MEM_Camera.connectedVob+72),  mulf(MEM_ReadInt(MEM_Camera.connectedVob+68),  dist));
d[1] = addf(MEM_ReadInt(MEM_Camera.connectedVob+88),  mulf(MEM_ReadInt(MEM_Camera.connectedVob+84),  dist));
d[2] = addf(MEM_ReadInt(MEM_Camera.connectedVob+104), mulf(MEM_ReadInt(MEM_Camera.connectedVob+100), dist));
