One Snow

For the Holiday Season Challenge, I thought of creating some animating (flying) snowflakes. So I started with creating one piece of snow. My idea is that this snow should fall from about 30 meters above ground. It should fall with some acceleration but not to fast because it is light. It should also spin a little while falling. For an easy beginning, I used a scaled rectangle to be the snow. If this works, this snow can be easily transformed into a more beautiful snowflake, and it can be multiplied to create many falling snowflakes.

Linnmon table

This is my second attempt at the Furniture Visualisation Design Challenges: The LINNMON Table. It took me less than an hour to create in the VRMath2 Editor. I think that I am getting better at mental visualisation and computation of scale, location, direnction of movement in 3D space. cheeky

Vika Byske Table

There are many design challenges set in the Furniture Visualisation Challenges page. I am very happy to be the first one to take on the first challenge. 

I chose the first furniture (Vika Byske Table) from the design challeges page. Because the dimemsions were already provided, there was no need to design this table. All I need was to follow the dimemsions given and try to create in the VRMath2 Editor.

Basic animation in VRMath2

Animating cube

Animation in VRMath2 is still in the development stage. I have created some Logo commands to achieve some basic animation. Animation in Logo can be very powerful because it is very easy to move the turtle around in 3D space and collect its position and orientation for animation.

Here is a basic introduction of animation in VRMath2. The whole animation framework will be revised and more GUI will be developed to enable easy creation of animations.

The infinite mobius space

Man walking in Mobius space

What if the world is a Mobius ring? Then would this man even walk to the end of the world?

A normal wrist band has inside and outside faces. If we cut the band, twist it 180 degrees then reconnect the band, then we have created a Mobius ring (or Mobius strip). A Mobius ring has only 1 face. You can observe the man walking continuously on the inside to outside, then inside, and outside again and again.....

Walking man

This is a test of animating an inline animation. In my previous walking man blog, I published an x3d file named walkman.x3d. In this blog, I tried to use the inline command to firstly insert the walkman.x3d as a single object (obj_0), then applied animation again onto this object.

The result is very succeesful. cool

Walking man

This is another test of animation in VRMath2. The construction of the man utilises basic 3D primitives including sphere, cone, sylinder, and cube. It is basically a trial and error approach to scale and apply material settings onto those 3D primitive objects. 

Animation is then applied to the arms and legs by careful considerations about their positions and orientations of movements.

Rotating Earth orbiting the Sun

Rotating Earth

This is a simple Earth and Sun model. This model is not to scale in terms of size and distance.

The rotation and revolution speeds are roughly to scale. The Earth in this model is rotating at 1 second per rotation. It is also revolving at 365 seconds per revolution.

The Earth has a tile of 23.5 degrees on its rotation axis to the orbiting plane. There are also some background stars (points). This model can be easily created using VRMath2 Editor. smiley

12 Tables

12 tables

In this blog, I am trying to use an existing LOGO program in VRMath2 called table.logo, then see if I can create a couple of tables using repeat command.
