示例#1

文件： WMOModelInstance.cpp 项目： 3dseals/wowmodelviewer

void WMOModelInstance::draw()
{
  if (!model) return;

  glPushMatrix();

  glTranslatef(pos.x, pos.y, pos.z);
  Vec3D vdir(-dir.z, dir.x, dir.y);
  glQuaternionRotate(vdir, w);
  glScalef(sc, -sc, -sc);

  model->draw();
  glPopMatrix();
}
