The Sun and Earth model

Submitted by Andy on Tue, 20/11/2018 - 13:47

Most of us may know that the distance between the Sun and the Earth is one AU (Astronomical Unit: 150,000,000 km). However, due to the various online solar system images, many of us are not clear about how the Earth and Sun look like in space in the actaul scale. The VRMath2 Editor is a 3D modelling application, and is capable of modelling our solar system. Therefore, I did an experiment in modelling the Earth and Sun using actual parameters. The results are not as good as I expected, but they do make me appreciate the awe of the solar system, and the difficulties in modelling and comprehending the science of our solar system.

Hemnes Desk

Hemnes desk

The Hemnes desk is a simple design. It has a table top and three compartments for storage. The programming could be simple but because I tool a challenge to use egocentric movements only, so it takes more than two hours to complete. Another reason for the longer time taken was that during the construction, I actually found a bug in the VRMath2 Editor, which puzzled me with some strange behaviour of the turtle movement.

In Web3D '17 Conference, James showed me how to do particle effect in Unity, which is very very cool. Then I thought that I may be able to create similar effect in my VRMath2 Editor. It turned out that it is quite easy to program in VRMath2, but of course the visual is not as good as in Unity. The simple codes, however, may be worth seeing, so here we go.

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) .

Quartz Molecule

Quartz molecule

All matter in the world is compounded from basic units of measurements called atoms. Atoms are made up of protons and neutrons, making the nucleus in the centre and electrons, which are much lighter in rings around it. Elements are substances made from only one type of atom, although when different atoms combine, they form compounds, or molecules. In a compound the atoms are being held together with chemical bonds. In this blog, I will be talking about the structure and characteristics of the molecule quartz.

Sodium Flouride 3D Model

Submitted by cpark on Thu, 28/07/2016 - 22:51
My partner and I have choosen Sodium Flouride to base this blog on and create a virtual 3D model of it. In this blog I will show the 3D model of the Sodium Flouride made by using the VR maths program. Then I will give details on the composition, structure, and characteristics of the molecule. Further information, questions, interesting ideas and difficulties faced in the programming will be discussed. Links for the logo and code used will be provided.

The Potassium Atom

Submitted by Rangerence on Thu, 28/07/2016 - 13:00

Potassium is a chemical element classified the atomic symbol 'K' on the Periodic Table. As the seventh most abundant element on Earth (2.6% abundance in Earth's crust), potassium is found in a wide array of industries, despite being commonly known for its integral role as a mineral that allows human cell function and its presence in bananas. Some applications of potassium are (but not limited to) potassium-based fertilisers, pharmaceuticals and manufacturing. Discovered in 1807 by Sir Humphrey Davy, its abundance and simple atomic structure has allowed for exhaustive research and application regarding potassium.
