The Sun and Earth model

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 model 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.

Earth Cross Section

Earth Cross Section

In the X3DOM mailing list, there was a discussion about constructing solid geometry. One application of solid geometry is to model the cross section of Earth. Unfortunately, solid geometry is not supported in X3DOM. However, the cross section can be achieved by using other geometry available in X3DOM. Here is an example.
