[Plib-users] sgCoord question...

[Cameron B. <ko...@da...>]

An sgCoord has xyz and hpr which seems to make it perfect for holding
a 'center of view' position + view rotations.

But if I hit the 'forward 1 unit' key I need to rotate (1,0,0) by hpr
and then add it to xyz. Is there a shortcut to do that that I have
missed? 

Ie, something like sgCoordxyzAddVec3(sgCoord *pos, sgVec3 *delta )

Currently Im doing:

  void  GR::move(int forw,int side)
  {
  sgVec3    d;
  sgMat4    m;
  d[1]=float(forw);
  d[0]=float(side);
  d[2]=0.0f;
  sgMakeIdentMat4(m);
  sgMakeRotMat4(m,camera_point);
  sgXformPnt3(d,m);
  sgAddVec3(camera_pos,d);
  }

but that feels ugly...
