# Measurement

## Hemnes Desk

The Hemnes desk is a simple design. It has a table top and three compartments for storage. The programming could be simple but because I tool a challenge to use egocentric movements only, so it takes more than two hours to complete. Another reason for the longer time taken was that during the construction, I actually found a bug in the VRMath2 Editor, which puzzled me with some strange behaviour of the turtle movement.

## A pot of green

It is hot summer (in Australia), plants and grass are quite stressed with dry and heat condition. Some succullent plants can survive easier, and I happen to see a pot of Snake plant, and think that I can create a 3D version of it.

## Sea simulation

In junior high school maths, there are usually questions about measuring the angle of depression and/or distance using trigonometry. Common examples could be like "Find the angle of depression from a lighthouse beacon 112 m above the sea level to a boat that is at a horizontal distance of 1.5 km from the lighthouse". A picture (not to scale) may be given as the one on the right. But then, what if the scenario is in 3D?

## LITHIUM 9D

All the objects that surround us in our lives are made of extremely small particles invisible to the naked eye.

## Sodium Fluoride

Tis is my introduction

## Animated Atomic Model

Here is my first attempt at a transforming model, I found it useful to give the centre a texture to conceptualise what was "spinning".  I have not yet worked out how to roll up and tilt right at the same time (moving both axis').

## Bali Hut

In my backyard, there is a Bali Hut. Before purchasing this house, we liked this piece of outdoor structure, and thought we can enjoy some outdoor leisure there with family and friends. And we did. Our hut is a very solid architecture. We decorated with artificial turf and fences on the three sides of the hut. It has become a comfortable place for our weekend breakfast place and retreat anytime at home.

Because there is now furniture and fences, I thought I can make a 3D model to show what it looks like by itself.

## 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.

## Palm Tree Leaf

Outsite my office window, there are many palm trees. I thought about making one so it may be reused later to make a full tree.

## 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.
