Text-guided 3D shape generation remains challenging due to the absence of
large paired text-shape data, the substantial semantic gap between these two
modalities, and the structural complexity of 3D shapes. This paper presents a
new framework called Image as Stepping Stone (ISS) for the task by introducing
2D image as a stepping stone to connect the two modalities and to eliminate the
need for paired text-shape data. Our key contribution is a two-stage
feature-space-alignment approach that maps CLIP features to …
