Sharing CNC Models 


Space technology has witnessed dramatic improvements over the years, spurred on by private firms such as SpaceX and Bigelow Aerospace. Likewise, the ability to share images, objects and 3d animations via social media has evolved.  It is now possible to share interactive 3D movies via Facebook and Twitter using tools such as Sketchfab.

We are currently converting biological structures (e.g., CryoEM / Xray) for sharing via social media (www.sketchfabforscience).  We are now exploring if this new interactive technology can be used to share space technology developments via social media.

Bigelow Aerospace  developes expandable space stations, which could dramatiacally accelerate space exploration and colonialization.  We found wonderul images and 3d models on various websites related to their expandable space module technology (ref).  A full interactive 3D model of the B330 can be found on the Bigelow Aerospace website (ref).  Using a modified 3D model (found on 3D warehouse),  we uploaded to Sketchfab.  During the final step, we added a background image (from Bigelow Aerospace site), annoatations and lighting (see Figure 1).

As shown above, the interactive technology allows one to take a virtual tour of the Bigelow technology. Likewise, if you have Google Cardboard or other VR headsets (Oculus, Microsoft Hololens), the above technology can be viewed in Virtual Reality.  Once uploaded to Sketchfab, the above model can be directly posted to Twitter or Facebook for interactive viewing.  Likewise, the embed code can be pasted onto websites, such as seen here.


Compositing Full Scenes

In order to visual a space colony, we imported all the models into 3DS Max (see Figure 1).  The prototype scene was rendered as shown below (see Fig. 3).

Effects of microgravity on myogenic factor expressions during postnatal development of rat skeletal muscle


Manabu InobeIkuko InobeGregory R. AdamsKenneth M. BaldwinShin’Ichi Takeda

Postnatal development of rodent skeletal muscle is well defined (413272933), and this process occurs within 1 mo after birth (4). In other words, this time frame represents a critical window in which the skeletal muscles undergo a rapid muscle mass growth and MHC phenotype differentiation (4). It is apparent that neural and humoral factors regulate MHC transition from embryonic/neonatal to adult isoforms (29). Normal innervation appears to be needed for development of the slow (type I) isoform, whereas formation of fast (type II) isoforms, especially the IIb isoform, is dependent on the level of serum thyroid hormone (29). Thus both factors cooperate to differentiate each skeletal muscle into its respective inherent phenotype.
