From topic "LDD2PovRay Talk" page 17.

Because of the point of view of your render, it looks a bit like some kind of optical illusion at first glance :laugh:

Yes, LDD2PovRay can create optical illusions. :sweet:

illusion created by Edward H. Adelson, Professor of Vision Science at MIT.

I remake it by Lego LDD2PovRay.

Lego tile A and B are exactly the same shade of gray.

My eyes do not believe you, but my picture editor does. :laugh:

Well done, very good and probably tricky job to make it like this only by rendering. :thumbup:

Wow, that illusions is really convincing. At first, I thought you were playing a silly prank with us Nachapon, but the two tiles are really the same shade. Amazing.

Thanks, Superkalle. This one also one of my favorate optical illusion. Original pic(3300 x 1536)

Not enough parallel with the line formed by the studs, but very nice otherwise.

Since the shrinking is part of the brick position transformation, it is used also by POV-Ray and that's why it gets also rendered like that. Transformations are taken exactly as they are stored in the LXF file.

You are right, I didn't fine adjust the position this time. This bug is useful to use with Ldd2povray .

Very well done, Nachapon, great work!

I have a problem: I don’t get behind your trick. How did you realize the penrose triangle? It is still a miracle to me. I would highly appreciate if you could let us know and share your technique. I do not assume that you created some special parts.

@Papacharly: Thanks, I'm glade you like them.

Only the triangle was cheat by render twice. Two different L shape models with same camera angle, then combine two images afterward.
