Rotating ElevationGrid

Rotating ElevationGrid

Someone asked about an ElevationGrid rotating about its center in the X3DOM User Mailling List, so I created this one using VRMath2 Editor to demonstrate that it is quite easy to create one. The idea in this demo is to have the center of ElevationGrid at 0,0,0 then move the ElevationGrid into an empty Transform node. The OrientationInterpolator is then applied on to the outer Transform node.

Linnmom Adils Table

Linnmom Adils Table

It has been a while that I have not looked into the Furniture Visualisation Challenge.  I have been reading a thesis and thought that I should take a break to play with creating 3D virtual world. I am getting better and better at creating a table, but perhaps I picked an easy one, so it only took me some 10 minutes or so to write a Logo program to create this LINNMON/ADILS table.

A simple angel. I used Andy Yeh's snowman to make this by changing the values in his code to learn the commands.

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)

Cube and Prism

This cube can be used in a classroom to demonstrate to students the differences between cubes and rectangular prisms.

This collection of shapes is the result of my learning the LOGO programming language.

3D Graphing

Submitted by Andy on Tue, 11/03/2014 - 14:59
3D Plot

There are many 3D visualisation software for mathematics. Most of them allow easy input of a function to create a 3D graph. VRMath2 also allows creation of 3D graphs. It may not be so easy if compared to other software. But I think that VRMath2 is better for learning because it provides more opportunities for construction throught programing. I call this the power of "Programming driven 3D modelling and visualisation".

Ice Cream Cone

Ice Cream Cone

Hello, I have created an ice cream cone and I would like to show you how I did it. This simple ice cream cone has a cone and a sphere. The cone and sphere will overlap (intersect) a little bit. In this virtual ice cream cone, I have used both the graphic user interfaces (GUIs) and the Logo programming. When I completed it, I saved the Logo program (.logo file), the 3D world (.x3d file), and a screenshot (.png file) so I can show you in this blog.
