Eric Hunt's recent piece on the homicidal gas chamber of crematorium 1 in the Auschwitz main camp maintains that "a 3D representation of the important area of Crematorium 1 is useful to understand this hole hoax". Carolyn Yeager's blog announces that Hunt's "3D imagery demonstrates the Auschwitz Hole Hoax". Actually, Hunt's "3D imagery" does not really help to understand the distribution of openings in the roof of the gas chamber better than a 2D image. The 3D effect looks nice, but that's it. It does not add anything to the issue, which hasn't been already shown by the 2D images published by Carlo Mattogno in Auschwitz: Crematorium I, p. 124 and its ugly RODOH variants (but how a 3D image can actually help to understand something is shown here for the gas chamber of crematorium 2 in Birkenau).
As I have pointed out previously, the whole argument relies heavily on the reliability of a single blueprint. Furthermore, if anything, it would suggest that the Poles have not properly reconstructed the gas chamber and its gas openings after it was converted into a bomb shelter by the SS after the gassings were ceased in the Auschwitz main camp. In fact, some of the more competent and independent witnesses (Stanislaw Jankowski, Hans Stark and Hans Aumeier with his lower estimate) have provided a figure of 2 for the number openings, and not 4 as assumed by the Polish reconstruction. Aside this, there is even a possible motive for the precaution to place a gas opening directly next to the door, especially when lacking experience with the door's stability during mass murder with poison gas: to kill the victim next to the door first and shield it from attempts to get breached.
The argument brought forward by Mattogno raises some question on how the original gas chamber looked like and why it was made like this, but it does not demonstrate a hoax, not that the Poles have created anything to deceive nor that no homicidal gassings were carried out in crematorium 1.
