It’s finally finished! A version of iSculptor made just for the iPad called: iSculptorHD. It is currently going through the Apple approval process. I’ll keep you posted when it has been approved.
There are no new modeling features (yet) but, you can play with larger models (up to around 5000 faces), it takes the extra real estate of the iPad into account, you can rotate the iPad in any direction and model in portrait or landscape modes, it has a movable tool bar for the buttons, and you can import and export models using iTunes. It is not a universal app, which means if you want a copy for your iPhone/iTouch you need iSculptor, if you want a copy for your iPad you need iSculptorHD.
