Ripple test

This is my first water ripple experiment. I found a function on Youtube and had a quick experiment. The ripple effect is not perfect but could be a good start for whoever is interested to refine it.

MERGA38 Presentation

This is my first attemp to create a 3D virtual world for a conference presentation. This presentation is for my paper titled "Mathematics, Programming and STEM" published in MERGA 38 conference proceedings.

Bouncing Spring

Bouncing is fun. A spring has potential (elastic?) energy that has many uses in our life. Can you think of any uses? I just had a front suspesion replace in my old car. There are two big springs (or perhaps 4, I did not check back wheels) on top of the two front wheels. The two springs make sitting in the car comfortable by obsorbing forces and only bouncing slightly when driving (on rocky road).

Interactive Earth Cross Section

Earth Cross Section 2

This is a slightly improve Earth Cross Section model of the previous one, with added animation and some interaction. Previously, the focus was on using VRMath2 Editor to construct the model. This time, the focus is on the learning about the Earth's geo structure. This is one of the main purpose of VRMath2 as a learning community for all to create, share, discuss and learn.

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.
