Hi, I was wondering about creating a three dimensional landscape using Vision Egg. We wanted to have a closed loop setup with an insect running on a ball controlling the translation and rotation through and environment. Would using the texture drum setup be best or is there another way to 'create' a fictive three dimensional environment.
It's certainly possible, but there's no support in the VE for automatically building a virtual 3D landscape. Instead, you would have to manually create all visible objects out of 3D textured rectangles whose coordinates you'd pass in yourself manually. This is a reasonable approach for low numbers of rectangles, but doesn't scale well to more complex environments, in which case you really want what's called a scene graph.
And then there's the issue of calibrating the display so that the spatial representation of the objects is correct. This could be done by approximating your drum with a series of rectangular projection screens, each showing the output of a camera pointing in a different direction within the virtual world. Again, it's possible in the VE, but involves a lot of manual setup.
I hope that helps and I wish I could name an out of the box solution, but unfortunately I don't know any...
