Newton's cradle twist

Newton's Cradle

Recently, there is discussion about pendulum wave effect produced using the Newton's cradle. There are many YouTube videos about pendulum waves. Having seen some of these "amazing" wave effect, I thought that VRMath2 Editor should be able to produce a fake, but good enough to show the effect of pendulum wave simulation. And here you go, see the 3D simulation below.

Sea simulation

sea simulation

In junior high school maths, there are usually questions about measuring the angle of depression and/or distance using trigonometry. Common examples could be like "Find the angle of depression from a lighthouse beacon 112 m above the sea level to a boat that is at a horizontal distance of 1.5 km from the lighthouse". A picture (not to scale) may be given as the one on the right. But then, what if the scenario is in 3D?

A boat with a sail

Boat

A classic boat has a main body (hull) and a mast with a main sail. Using the build-in primative objects, there could be some possible boats contructed. In this blog, I used three objects: a SNOUT for the hull, a CYLINDER for the mast, and a 2D PIE for the sail. Of course these objects are scaled and textured with materials and images to be looking like (I hope blush) .

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.
