Hi! I’m making an “impossible geometry” model, but i find it hard to align in the viewer. Is there a way to align the camera precisely? I’ve seen a post about API and some sort of code, but I don’t get it at all!

Awesome! Can i ask you how did you set the camera to the perfect angle?

#6

you should be able to adjust the focal point/fov in your modeling software and match Sketchfab’s to that, if that helps.

Here’s my optical illusion… I didn’t have much time to refine it, but I’m happy with the overall concept:

I’ve somehow managed to align the view with the mesh, it is a bit broken because it can’t align perfectly, but it works

I made one of those two-face-silhouette things. It’s hollow all the way through.

This one might be a bit of a stretch; I wanted to make one of those inflatable costumes with the fake legs on the side that make it look like you’re riding a dinosaur:

Always interesting to see where the prompts take people. Loved both of the Pac-man ones yesterday.

My submission for day 2 of the 3December challenge - Optical Illusions.

I saw a similar artwork a while ago from another artist (Perspecitve) and I really liked it but never had the time to try it out myself. So with todays topic I finally had a reason to try it and it was actually much easier than I thought and really fun to make :slight_smile:

Making an optical illusion shape was tons of fun and loads of practice!

Glig and Glog.

My take on an Ames Room optical illusion. I had almost no time today to work on this so I’m just happy I finished it. There is a vertex weighting issue that only appears in Sketchfab that I didn’t have time to diagnose, sadly.
