while(device->run())
{
driver->beginScene(true, true, SColor(255,100,101,140));
smgr->drawAll();
guienv->drawAll();
SMaterial mat;
mat.Thickness = 100;
mat.AntiAliasing=true;
mat.Lighting = false;
driver->setMaterial(mat);

driver->draw3DLine(core::vector3df(2.0,3.0,4.0),core::vector3df(2.0,3.0,8.0),video::SColor(255,0,0,255));
driver->endScene();

this will work as long as there are no other elements in the scene !!!

if you draw manually you'll have to set the tranformation matrix first:

Code: Select all

      matrix4 tmat;
      driver->setTransform(ETS_WORLD, tmat);
      driver->draw3DLine( ... );
