Palm tree

Palm tree

This is a simple design and visualisation of a palm tree.  The palm leaves are borrowed from a previous blog. The new part is the tree trunk, which is an EXTRUSION object. Before the inclusion of EXTRUSION in VRMath2 Editor, tree stems or branches may be just cylinders. Using EXTRUSION, more irregular tree trunks can be achieved.

Spur gears

Spur gear set

Finally, not perfect at all but working gear set in 3D. Thanks to asplech's blog about involute gear and this Spur Gear document, I finally get to know better about these cogged wheels.

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.

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.

Hypercube - Tesseract

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

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.

Truncated cube

Truncated cube

I have created a truncated cube, I would like to tell you about the truncated cube and how I created it.

A shield or spider web?

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.

Truncated Icosidodecahedron

Image ALT text

The truncated icosidodecahedron is made up of 30 square faces, 20 regular hexagonal faces, 12 regular decagonal faces, 120 vertices and 180 edges. The dihedral angles for this Archimedean solid are as follows:

  • between a hexagonal face and a decagonal face: 142.62 degrees (6-10)

  • between a square face and a decagonal face: 148.28 degrees (4-10)

  • between a square face and a hexagonal face: 159.095 degrees (4-6)
