Gear 2D Prototype

gear2d prototype

Following the circle involute blog, I thought about creating a gear procedure for easy creation of different gears. The method used is quite differnt to the involute idea but the turtle geometry way of thinking and doing the gears. This prototype procedure utilised a simple regular poygon formula (repeat :sides [ fd 1 rt 360/:sides ]) and some built-in commands such as TOWARD and SETHEADING to rotate the turtle and get the directions needed.

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.

Bouncing spring

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.

Waves at sea

Sea surface

Following my previous blog about 3D function graphing, I did another experiment to animate the 3D graphs. In this blog, I used the same 3D function f(x,z) = x*z^3-z*x^3 to generate two sets of heights. Then a VECTORINTERPOLATOR (or VECINT) was used to animate this 3D graph. It looks to me like a wave on the sea surface. What do you think?

Analog clock

Analog clock

The TIMESENSOR of X3D is quite a complicated time mechanism to understand. As I have created some commands for easy animation, I thought that it would be interesting to test the TIMESENSOR with an analog clock.

The Tesseract has awaken....

I am always fascinated by the visualisation of 4th dimension or even n-th dimension in our 3D space. The 4th dimension here is not about time, but the beauty of the abstract geometrical dimensions that exist in the mathematical world.

Helium atom

Since version 0.9.1 of VRMath2 Editor, animation has become quite easy. I have previously made a hydrogen atom and now I can't resist to create the second one in the periodic table, the helium atom.

Hydrogen atom

I have been contemplating the animation framework and recently implemented a SPIN command to make spin animation easy for even young children. In order to show how to spin objects, I have created this hydrogen atom simulation to demonstrate the SPIN and a few new commands.

rotating cube frames

Some time ago, I have seen cube frame animation in a gif file. I am not sure how that was created and using what software, but to me it is quite easy to do in VRMath2 Editor. In this blog, I only did the rotation. If translation (change of location) is also animated it would be more interesting. But I think I will leave it to my future blogs.
