3D Sampling is presented as a new method for comprehensive rearrangement and composition of 3D scan data, allowing multi-scale manipulation of surface texturing and subsequent fabrication and re-evaluation using 3D printing. Analogous to sample-based music, 3D Sampling contributes new frameworks, tools, and compositional strategies for the digital remixing, hacking, and appropriating of material qualities, performances, and behaviours directly from physical samples to produce new designs. Case studies are presented which demonstrate 3DJ: a prototype 3D modelling tool for synthesizing haptic and optically performing textures from 3D scangenerated source material, which can be applied in the context of other 3D modelling techniques.

This paper presents 3D Sampling as a new method for the comprehensive rearrangement and composition of 3D scan data, allowing multi-scale manipulation of surface textures and subsequent fabrication and re-evaluation using 3D printing. Analogous to sample-based music, 3D Sampling contributes new approaches for digital remixing of performance features, and structures of real world objects. Building on previous research, this paper presents a new design system, "3DJ", which uses an interactive evolutionary design process to synthesize new texture designs from 3D scans. Case study examples are presented, including the design of a texture-based architectural roof structure, to demonstrate the design tool.
