    Pokestop

    The Pokemon Go App has caused quite a global disturbance since its recent release (date?). Facebook access rate was descresed and more people access Pokemon Go daily than Twitter.  People are busy catching Pokemonsters on the roads, at schools and homes, and in the parks. This short video taken at NYC Central Park shows how popular it is. A search on Twitter for Pokemon go can get a quick understanding of this global phenomenon. Are you playing?

    Bali Hut

    Bali Hut

    In my backyard, there is a Bali Hut. Before purchasing this house, we liked this piece of outdoor structure, and thought we can enjoy some outdoor leisure there with family and friends. And we did. Our hut is a very solid architecture. We decorated with artificial turf and fences on the three sides of the hut. It has become a comfortable place for our weekend breakfast place and retreat anytime at home. 

    Because there is now furniture and fences, I thought I can make a 3D model to show what it looks like by itself.

    X3D: behind-the-scenes

    Here is a look at the 3d technology which drives vrmath behind the scenes. It is called X3D and has its own web site. Understanding this technology not only helps in how vrmath extends turtle graphics into 3d but opens the door to a large world of virtual reality in general (x3dom, web3d). It turns out that the vrmath editor is itself a good tool to get to know X3D. Here is how.

    more gears, fast

    4 gears

    I updated the involute (curved teeth), helical gear generation procedure to use Extrusion rather than IndexedFaceSets. Extrusion automatically supports the back and front faces of the gears, and a smooth appearance by producing a mesh with points shared by triangles. So the logo code could be streamlined and therefore is now much faster generating gears.

    Extrusion helical gears

    I recently just included Extrusion object into VRMath2 Editor and started to experiment its applications in creating 3D objects. It is quite easy to use Extrusion to create Spur Gears, but here I am showing how it can be used to created Helical Gears.
