This was one of my first larger projects in Bryce3D (although small compared to some I'm doing now). I thought, that if you want to build a spaceship, you will need an asteroid for the basic materials. Instead of mining an asteroid and slowly build a ship out of that, why not build your ship around the asteroid? That way you can start your travel even before you have finished building and you always have a stock of resources with you. OK, I admit, your ship would be a bit too heavy, but it certainly would look cool :). That's why I decided to model it, and this is the result. Update: This is a revamped version of the asteroid ship, with higher resolution meshes and textures and a few details added. These changes were necessary to be able to render the high-res image that was used as a book cover.
