Each piece of a Crafter model is attached to another piece in the model in a hierarchical fashion, with the attachment point and rotation angle specified. Crafter's library of parts is specially designed for building spacecraft. It includes geometric objects such as cylinders, ellipsoids and rectangular plates and also an array of trusses. The user can control appearance characteristics, such as color, shading and texture mapping, at any level of the model. Crafter is available on SGIs, Suns and HPs.
Crafter is available for download free of charge.
