@John, @Simeon - I recently installed an android app on my Nexus 7 called viewER. I was using it to check some of the models I have found, as I am still getting hit and miss results with Craft. It does seem to have a higher success rate than Craft so I am sure there is something I don’t understand with setting up a viewer in Craft or the code routines used by Craft for loading models are too rigid/precise and reject many poorly made obj files.
The main reason I posted this though was what I found with this ER viewer. See the following two links, one to the viewER website and the other to a video of a hologram effect using a truncated inverted pyramid. Must try this out with the android software and was wondering if you had seen this and implemented it in Codea?
Edit: Oooops, tried to use the links above in the editing bar - made a mess of it so reverted to good old HTML. Sorry.
