Methane Molecule

This is my first and simple construction of a molecule. I chose to do Methane (CH4), one atom of carbon and four atoms of hydrogen, because it takes the shape of a tetrahedron. In this blog, I used a different but simple method to construct this tetrahedron shape. There is a special angle in tetrahedron. With this special angle, we can easily construct a tetrahedron.

Light with switch

Light with switch

After much thinking and planning, I have finally implemented an initial behaviour framework. Behaviour is different to animation. But it may also have effect of animation. In this blog, I have programmed a desk lamp -- a spotlight with a switch. You can click on the switch to switch on and off the light. When you do, you can also hear a switch sound, so have your speakers turned on to enjoy the virtual simulation of light, shadow and sound.

Sundial

Some weeks ago, I have implemented the lighting components in VRMath2 Editor. There are three different lights: point light, directional light, and spotlight. In this blog, I am using the directional light to simulate the sunlight for casting a shadow on a sundial.

Rotating Earth orbiting the Sun

Rotating Earth

This is a simple Earth and Sun model. This model is not to scale in terms of size and distance.

The rotation and revolution speeds are roughly to scale. The Earth in this model is rotating at 1 second per rotation. It is also revolving at 365 seconds per revolution.

The Earth has a tile of 23.5 degrees on its rotation axis to the orbiting plane. There are also some background stars (points). This model can be easily created using VRMath2 Editor. smiley

DNA model

It was Wednesday, 17th of July. I met with a visiting scholar Xie Zuo Ru from China.  Xie is an awarding-winning high school teacher in the area of technology education. His research interests focused on the use of interactive media to promote science, technology, engineering and mathematics (STEM) education.  The interactive media refers to the small computers such as Arduino and Raspberry Pi that are affordable, programmable, and capable of transforming virtually any objects into input and output devices.  A wide range of interactive media applications such as turning a drawing of keyboard into a real keyboard or remote control of household appliances makes the teaching and learning fun and creative. He is also an expert in robotics and programming.
