Dear morphometricians, We are interested to analyze anatomical parts of coleoptera (i.e., head and prothorax) in 3D. We tested a method of data acquisition employing a 3D scanner with piezo-sensor technology (resolution axes x-y: 0.05 mm, axis z: 0.025 mm). Seemingly, it works very well, but it is very slow (serial port!). Besides, we cannot capture the horns apices, that are very narrow. Could someone give me information about the use of NextEngineDesktop 3D Scanner? I'm interested mainly in the resolution values. Is it fast or slow in 3D image acquisition? We are working on _very _small pieces, and dark (almost black), but the surface of coleoptera exoskeleton is characterized by a complex and fine sculpture. I'm wondering if the reticulate structure could interfere with a 3D analysis of laser scanner. Perhaps we have to opacize the surface (how?). Thank you very much for any suggestion. Angela Roggero
