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.

A pot of plant

It is hot summer (in Australia), plants and grass are quite stressed with dry and heat condition. Some succullent plants can survive easier, and I happen to see a pot of Snake plant, and think that I can create a 3D version of it.

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.
