It is not difficult to see which features would be needed in Bryce 7.
 

A while ago, I wrote a Bryce 6.1 vs Vue 7 Infinite article with a rather complete feature comparison. The features highlighted in red are the most interesting ones. Some of the things I noted as missing for Vue 7 have been addressed in Vue 8 (for instance the view flickering).

Fantasy pictures, free 3d models, 3d tutorials and seamless textures on Virtual Lands.
