[Plib-users] scaling with setTransform

[Krippel H. <neu...@su...>]

Hi to all

I am writing on a gamedesigner with plib and opende and QT.
(www.kcake.org)

In this examplecode i get the positon from opende and set it in the plib object
and scale it.

It works.
The problem is that the scaled objects redraw to lat.
Example: I drive with a car and the scaled opjects (ramp)are drawed to late
in the view.
  


void Barrier::setTransform (ssgTransform *objtrans, const dReal pos[3], const
dReal R[12],dVector3 dxyz)
{
  sgMat4 m;
  

  m[0][0] = R[0] ;
  m[0][1] = R[4] ;
  m[0][2] = R[8] ;
  m[0][3] = SG_ZERO ; //x

  m[1][0] = R[1] ;
  m[1][1] = R[5] ;
  m[1][2] = R[9] ;
  m[1][3] = SG_ZERO ;  // y

  m[2][0] = R[2] ;
  m[2][1] = R[6] ;
  m[2][2] = R[10] ;
  m[2][3] = SG_ZERO ;  // z

  m[3][0] =  pos [0] ;
  m[3][1] =  pos [1] ;
  m[3][2] =  pos [2] ;
  m[3][3] =  SG_ONE ;

  sgScaleVec3(m[0], dxyz[0]);
  sgScaleVec3(m[1], dxyz[1]);
  sgScaleVec3(m[2], dxyz[2]);
                  
  objtrans->setTransform(m);
}


Is the BSphere incorrect ??


A other question:

Can I resize objects ? (not scaling)


Thank You
